AB - We present an approximate analytical method to evaluate efficiently and accurately the call blocking probabilities in wavelength routing networks with multiple classes of calls. The model is fairly general and allows each source-destination pair to service calls of different classes, with each call occupying one wavelength per link. Our approximate analytical approach involves two steps. The arrival process of calls on some routes is first modified slightly to obtain an approximate multiclass network model. Next, all classes of calls on a particular route are aggregated to give an equivalent single-class model. Thus, path decomposition algorithms for single-class wavelength routing networks may be readily extended to the multiclass case. This article is a first step towards understanding the issues arising in wavelength routing networks that serve multiple classes of customers.

AB - The understanding of what constitutes a “good” production schedule is central to the development and evaluation of automated scheduling systems and their implementation in real-world factories. In this paper, we provide a definition of a schedule and discuss potential uses for a schedule within the organization. We then describe a number of different considerations that must be taken into account when assessing the quality of a schedule, and discuss their implications for the design and implementation of scheduling systems.

TI - Quantifying the benefits of cycle time reduction in semiconductor wafer fabrication
AU - Nemoto, K.

T2 - IEEE Transactions on Electronics Packaging Manufacturing
AB - In recent years, semiconductor manufacturing has become increasingly complex due to device size reduction. Hence the manufacturing cycle time, also called turn around time (TAT), which is defined as the time required from wafer input through probing test, becomes longer year by year. This renders the delay between the occurrence of process defects and their detection a significant problem. On the other hand, customer demands for faster delivery are increasing as product life cycles are getting shorter. Hence, TAT reduction is important for semiconductor manufacturers not only to satisfy customer requirements, but also to remain competitive in their market. This paper examines the financial benefits of TAT reduction in ramping up a new process using stochastic simulation. Results indicate that reducing TAT in the ramp-up phase is important, and that even small reductions can have significant effects over the life cycle of a process.

TI - Performance of decomposition procedures for job shop scheduling problems with bottleneck machines
AU - Uzsoy, Reha
AU - Wang, Cheng-Shuo
T2 - International Journal of Production Research
AB - Decomposition procedures for job shop scheduling problems, such as the shifting bottleneck (SB) procedure, have shown promising results for a variety of shop environments. However, they have primarily been tested using problems where all machines are identical in terms of processing time distribution. Many practical scheduling problems involve bottleneck machines which become the focus of scheduling efforts, as suggested by the theory of constraints. In this paper we examine the performance of several variants of SB, some of which can be interpreted as naive implementations of the TOC approach to scheduling. Our results show that both the solution time and quality of SB methods improve markedly when bottleneck workcentres are present. However, scheduling bottleneck machines optimally and using simple rules at other machines leads to poor performance unless the workload of the bottlenecks significantly exceeds that of the non-bottleneck machines.

AB - Abstract Drawing on the basic ideas of soft computing, we propose a fuzzy rule quantification method. It describes decision factors by membership functions of corresponding fuzzy sets and decision-making rules by fuzzy logic operations. The rule-based inference engine can be easily embedded into other quantitative computation methods for solving complicated problems. The method has been combined with genetic algorithms for application to two optimization problems in manufacturing systems, resource allocation in the Fuzzy Due-Date Bargainer (FDDB) and partner selection for virtual enterprises. Satisfactory results have been achieved.

T2 - International Journal of Production Research
AB - Since its introduction in 1987, the Malcolm Baldrige National Quality Award (MBNQA) has come to have a major influence in the assessment of quality efforts and systems. Many public and private institutions, for example, use the measures derived from this award programme to carry out self-assessments. Many programmes at the local, state and international levels are based on the MBNQA. Implicit in this evidence is the assumption that the MBNQA adequately captures the major dimensions of Total Quality Management. This study empirically assesses this assumption. Specifically, it assesses the extent of fit between the factors of the MBNQA and their measures. It also evaluates the extent to which these factors really do capture this important higher-level construct known as TQM. The results reported in this study are based on a field survey consisting of responses gathered from 526 plant managers within the US automotive industry. The assessment is carried out using confirmatory factory analysis and structural equation models.

AB - Over the past ten years, intense global competition has forced many firms to examine their business practices and to evaluate how to meet the challenges economic globalization has presented. Underlying these efforts has been an examination of strategic priorities and in particular recognition of the need to improve product and process quality. While quality improvement has become a pervasive element of business strategy, allowing some companies to respond to increasing competitive pressures, it has not been universally effective. This study uses a survey of over 300 senior quality personnel to identify the challenges businesses face from globalization and how strategic initiatives, and in particular, quality improvement efforts, are used to respond to them.

T2 - IEEE Transactions on Engineering Management
AB - This paper explicitly examines the relationship that exists between total quality management (TQM) and environmentally responsible manufacturing (ERM) systems. It has been presumed in numerous past studies that such a relationship does exist. It has been argued that those firms that have successfully implemented a TQM system are better positioned to successfully implement an ERM system. This relationship, however, has not yet been statistically and empirically evaluated. In this study, the authors evaluate this relationship using a large-scale survey of plant managers as the data source and confirmatory factor analysis and structural equation modeling as the statistical tools. The study develops a series of measures for various aspects of both TQM and ERM. The results show that there is indeed a strong relationship between TQM and ERM. In many ways, ERM is conditioned by the presence of TQM. Furthermore, ERM systems have a parallel structure when compared to TQM systems.

AU - Mcdermott, C.

T2 - Journal of High Technology Management Research
AB - Concurrent development activities and strategic supply chain management have become staples of the new product development (NPD) process over the last 15 years. Although this is beneficial, often the advice given comes in a “generic” form, based on the assumption that the similarities among NPD efforts are more important than the differences between them. However, variation in the radicalness of projects can make a significant difference in the way that they should be managed. This paper explores the processes associated with the development of radical new products. Based on interviews with project managers and engineers in the United States and Japan, this paper puts forth three propositions, which we summarize in a model aimed to help managers decide whether the “degree of radicalness” of the product may require changes in the organization's NPD process.

We view an e-commerce community as a social network, which supports reputations both for expertise (providing good service) and helpfulness (providing good referrals). We study the small-world phenomena such as the emergence of subcommunities, and pivot vertices (which link different subcommunities) in the social network, and discovered that the quality of the network improves with the presence of a pivot.

AB - Protocols represent the allowed interactions among communicating components. Protocols are essential in electronic commerce to constrain the behaviors of autonomous entities. Traditional representations of protocols include actions, but not their content, which limits their applicability in settings where autonomous entities must flexibly interact to handle exceptions and exploit opportunities. We develop a commitment-based representation, which provides a content to the protocols, enabling flexible execution. We show how an existing protocol can be systematically enhanced to yield a protocol that allows the given actions as well as other legal moves.

AB - The integration of forest plantations, sustained yield regulation of industrial wood fiber, and market responses of private forest landowners determine sustainable forest management for timber. The world has approximately 3.4 billion ha of forests; 230 million ha of all types of forest plantations; and 40 million ha of industrial wood plantations. A sample of private and public forestry analysts in the world indicated that they use a variety of timber harvest regulation approaches. These include Model I and Model II model formulations; Simplex and heuristic model solution approaches; sustained yield harvest constraints; and ecological constraints. An analysis of the forest plantation area and timber supply situation in the U.S. South indicated that intensive forest management can balance softwood timber inventories and timber harvests, at slightly increased real timber prices. The data on forest plantations and growth rates, as well as our survey of harvest regulation, indicate that the forest products industry and other forest owners have the means to achieve and modeling capabilities to measure and implement sustainable timber management. If this potential is realized, increased productivity in managed forests will lessen timber harvesting pressures and enhance the protection of natural forests.

AB - Abstract A large number of heuristic search algorithms are available for function optimization. Each of these heuristics, e.g., simulated annealing, genetic algorithms, tabu search, etc., has been shown to be effective at finding good solutions efficiently. However, little work has been directed at determining what are the important problem characteristics for which one algorithm is more efficient than the others. By examining two problems, the location-allocation problem and the quadratic assignment problem, characteristics of successfil tabu search are illustrated. A tabu search for the location-allocation problem is described and implemented. The results of this tabu search are compared against a genetic algorithm. For the quadratic assignment problem, tabu search has been shown more effective than genetic algorithms; however, for the location-allocation problem, the genetic algorithm finds better solutions more efficiently than tabu search. To. investigate what characteristics of the location-allocati...

T2 - Journal of the Chinese Institute of Industrial Engineers
AB - Abstract Global competition is demanding innovative ways of achieving manufacturing flexibility and reduced costs. One approach is through cellular manufacturing, an implementation of the concepts of group technology. The design of a cellular manufacturing system requires that a part population be at least minimally described by its use of process technology (padmachine incidence matrix) and partitioned into part families and that the associated plant equipment be partitioned into machine cells. At the highest level, the objective is to form a set of completely autonomous units such that inter-cell movement of parts is minimized. This paper presents a stochastic global optimization technique utilizing genetic algorithms (GAS) and local improvement procedures (LIPs) to solve the cell design problem. The combination of LIPs with GAS is shown to improve the performance of the GA in terms of solution quality and computational efficiency. Several different methods of incorporating these procedures into the GA are investigated. The concepts used in these hybrid techniques can easily be extended to other variations of the cell design problem as well as to other LIPs.

T2 - DECISION SCIENCES
AB - Much of the research on quality practices and performance reflects a resource-based perspective of the firm, dealing primarily with internal issues of managerial and technological competence in developing and executing an effective TQM strategy. The neoclassical perspective on the influence of the competitive environment on quality practices and performance remains conspicuously absent in the empirical quality literature. Our study aims to address this gap by examining the contingent role of international competition on quality management and performance. We develop and test an integrative framework of quality management, consisting of high involvement work practices, quality practices, quality performance, and firm performance. We then examine the contingent effects of international competition on the constructs and relationships of the framework. International competition was found to moderate the relationship between quality practices and customer satisfaction performance, as well as the relationship between high involvement work practices and firm performance. The moderator effects suggest interesting implications for quality theory and practice.

AB - In Part I of this series we described a set of computer-simulation models of the various components of the apparel-supply complex. Here we summarize the results obtained by exercising the models, with the main emphasis placed on whether or not the upstream operations of spinning, fabric production, and dyeing and finishing were capable of meeting Quick Response (QR) requirements for response time and service levels. In carrying out this work, questions arose about the kind of information systems required to link the various entities in the supply chain, alternative scheduling procedures, the possibility of interactive management-information systems that would allow rapid responses to the concerns of senior managers, and user-friendly means for technology transfer. We have also begun to explore the use of fuzzy mathematics to model the uncertainty and vagueness inherent in most supply-chain decision-making. Work on these topics is discussed here in Part II.

T2 - JOURNAL OF THE TEXTILE INSTITUTE
AB - Abstract In Part I of the series, we describe stochastic computer models that simulate operations in the spinning, knitting, weaving, dyeing and finishing, and cut/sew sectors of the textile industry. The models are scaled to represent a supply chain designed to feed a garment-manufacturing operation involving four or five plants, i.e. part of each plant's output is ‘dedicated’ while simultaneously providing yarns and fabrics to the industry at large. Each of the sector models is unique because of the very different types of processing technology employed. The models are linked by means of streams of fabric orders from the manufacturing plants that make a range of garment types requiring many different fabrics for Basic (year-round sales), Seasonal (two or three seasons per year), and Fashion (shelf lives of 8–12 weeks) goods in a broad range of colors. In addition to each plant's product ranges and order sizes and frequencies, particular attention is paid to the machine-scheduling algorithms, although the models are deliberately kept at a ‘high’ as opposed to a ‘shop-floor’ level. The purpose of this modeling is to allow senior management to answer broad questions about the plants' ability to operate in a Quick Response environment. The various model outputs reflect this, having a heavy emphasis on on-time shipments, back-order levels, and service levels. In Part II of the series, we shall present the QR-related operating results to date, a description of a master-scheduling procedure to orchestrate the operations of the supply chain, ideas on an improved scheduling method, and an account of the construction of neural-network decision surface models as a decision support tool. We also overview ongoing efforts in technology transfer and in using ‘fuzzy’ mathematics to model the vagueness and uncertainty inherent in the supply- chain decision-making environment. The research effort of which this is a part is ongoing. We present these results in the hope of encouraging others to help carry the investigations forward.

AB - Abstract Under the assumption that one of two given models is the real underlying model of the system, a proper auxiliary signal is defined as an input signal that allows one to select the correct model. It is assumed that there is no knowledge prior to the beginning of the application of the auxiliary signal and that detection is to be done within a specified detection horizon. Under the assumption that the noise energy is bounded, the separability index is defined as the least energy of a proper auxiliary signal. A method for computation of this index is presented.

T2 - JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA
AB - Four anhysteretic polarization models that have been used in the literature to evaluate data acquired from lead magnesium niobate (PMN) are analyzed and compared. Derivations of two of the models from assumed spatial distributions of dipole energy states, using first physical principles, are presented. A third model is derived from a suitable integral averaging calculation. These derivations are used as the basis for developing an integral equation for determining an energy-state distribution that produces a fourth model, which was not originally formulated in terms of an assumed distribution. A new polarization function is also presented. Excellent approximations to each of the four polarization functions of interest can be deduced from this new polarization function by adjusting the numerical value of just a single parameter. An application of two of the models to data is presented. It is shown that it can be necessary to consider a sample to be an admixture of two distinct species of poles, in the sense that two polarization functions must be added together in order to accommodate the data.

TI - On state constraint representations and mesh-dependent gradient projection convergence rates for optimal control problems
AU - Dunn, JC
T2 - SIAM JOURNAL ON CONTROL AND OPTIMIZATION
AB - Two distinct nonlinear programming formulations are investigated for ODE optimal control problems with pointwise state and control constraints. The first formulation treats the differential equations of state as an equality constraint in the conventional manner. The second formulation employs a different equality constraint entailing the integrated state transition map. Related convergence rate estimates are developed for augmented gradient projection methods and discrete-time approximations to a large representative class of ODE control problems. In the first formulation, the rate estimates are mesh-dependent, and the predicted number of inner loop gradient projection iterations needed to achieve a fixed small deviation from the optimal value of the augmented Lagrangian is inversely proportional to the square of the mesh width. In the second formulation, the convergence rates and predicted iteration counts are mesh-invariant. The computational costs-per-iteration in the two formulations are comparable. These estimates elucidate previously published numerical experiments with augmented gradient projection% AGP methods and constrained regulator problems.

T2 - EUROPEAN TRANSACTIONS ON TELECOMMUNICATIONS
AB - We consider the problem of supporting multipoint communication at the MAC layer of broadcast WDM networks. We first introduce the midticcut rhroughprrt as the performance measure of interest and we show that it depends on two measures that have previously been considered in isolation, namely, the efficient use of channel bandwidth and wavelength throughput. We then present a new technique for the transmission of multicast packets based on the concept of a Lzirninl receiver, a set of physical receivers which behave identically in terms of tuning. We also demonstrate that the number of virtual receivers naturally captures the performance of the system in terms of multicast throughput. Consequently, we focus on the problem of optimally selecting the virtual receivers to maximize multicast throughput, and we prove that it is Ji'P-complete. Finally, we present four heuristics of varying degree of complexity for obtaining a set of virtuat receivers that provide near-optimal performance in terms of multicast throughput.

We present the systematic formulation of Gaussian filters and develop efficient and accurate numerical integration of the optimal filter. We also discuss the mixed Gaussian filters in which the conditional probability density is approximated by the sum of Gaussian distributions. A new update rule of weights for Gaussian sum filters is proposed. Our numerical tests demonstrate that new filters significantly improve the extended Kalman filter with no additional cost, and the new Gaussian sum filter has a nearly optimal performance.

AU - Wu, F
AU - Grigoriadis, KM

T2 - INTERNATIONAL JOURNAL OF CONTROL
AB - In this paper, we seek to provide a systematic anti-windup control synthesis approach for systems with actuator saturation within a linear parameter-varying (LPV) design framework. The closed-loop induced L2 gain control problem is considered. Different from conventional two-step anti-windup design approaches, the proposed scheme directly utilizes saturation indicator parameters to schedule accordingly the parameter-varying controller. Hence, the synthesis conditions are formulated in terms of linear matrix inequalities (LMIs) that can be solved very efficiently. The resulting gain-scheduled controller is non-linear in general and would lead to graceful performance degradation in the presence of actuator saturation non-linearities and linear performance recovery. An aircraft longitudinal dynamics control problem with two input saturation non-linearities is used to demonstrate the effectiveness of the proposed LPV anti-windup scheme.

AB - The linear-quadratic (LQ) control problem is considered for a class of infinite-dimensional systems with bounded input and output operators, that are not exponentially stabilizable, but only strongly stabilizable. A sufficient condition for the existence of a minimizing control and of a stabilizing solution to the associated LQ Riccati equation is given. The main contribution of this paper is the convergence of the stabilizing solutions of a sequence of finite-dimensional Riccati equations to the strongly stabilizing solution of the infinite-dimensional Riccati equation. The result is applied to a model of propagation of sound waves in a one-dimensional wave-guide.

Previous semantics have largely been mentalistic in their orientation and are based solely on the beliefs and intentions of the participating agents. Such semantics are not suitable for most multiagent applications, which involve autonomous and heterogeneous agents, whose beliefs and intentions cannot be uniformly determined. Accordingly, we present a social semantics for ACLs that gives primacy to the interactions among the agents. Our semantics is based on social commitments and is developed in temporal logic. This semantics, because of its public orientation, is essential to providing a rigorous basis for multiagent protocols.

TI - A general mixture model approach for mapping quantitative trait loci from diverse cross designs involving multiple inbred lines
AU - Liu, YF
AU - Zeng, ZB
T2 - GENETICAL RESEARCH
AB - Most current statistical methods developed for mapping quantitative trait loci (QTL) based on inbred line designs apply to crosses from two inbred lines. Analysis of QTL in these crosses is restricted by the parental genetic differences between lines. Crosses from multiple inbred lines or multiple families are common in plant and animal breeding programmes, and can be used to increase the efficiency of a QTL mapping study. A general statistical method using mixture model procedures and the EM algorithm is developed for mapping QTL from various cross designs of multiple inbred lines. The general procedure features three cross design matrices, W , that define the contribution of parental lines to a particular cross and a genetic design matrix, D , that specifies the genetic model used in multiple line crosses. By appropriately specifying W matrices, the statistical method can be applied to various cross designs, such as diallel, factorial, cyclic, parallel or arbitrary-pattern cross designs with two or multiple parental lines. Also, with appropriate specification for the D matrix, the method can be used to analyse different kinds of cross populations, such as F 2 backcross, four-way cross and mixed crosses (e.g. combining backcross and F 2 ). Simulation studies were conducted to explore the properties of the method, and confirmed its applicability to diverse experimental designs.

AB - This study employs structured interviews in a field setting to develop an in-depth understanding of how a specific human resource decision affected manufacturing performance at 30 plants using advanced manufacturing technologies. Initial results suggested that there is no relationship between the skill level of operational employees and the level of performance of the installations. When a measure of “fit” between environmental characteristics and skills was employed, however, there was a significant relationship between the fit measure and performance.

A probabilistic model is developed to predict the different CV values obtained from the different instruments, and the results are compared with experimental values.

Incontrast to the star plot, this plot allows statistical inferences to be made for treatment and for factor effects. In contrast to ANOM, this plot is good for comparison in multiresponse experiments, a scenario becoming more commonplace in toxicology with the advent of increasing numbers of chemical mixture studies. An example of a 2 3 factorial chemical exposure experiment is considered here.

T2 - Journal of Intelligent Material Systems and Structures
AB - This paper addresses the modeling of strains and forces generated by magnetostrictive transducers in response to applied magnetic fields. The magnetostrictive effect is modeled by considering both the rotation of magnetic moments in response to the field and the elastic vibrations in the transducer. The former is modeled with the Jiles-Atherton model of ferromagnetic hysteresis in combination with a quartic magnetostriction law. The latter is modeled through force balancing which yields a PDE system with magnetostrictive inputs and boundary conditions given by the specific transducer design. The solution to this system provides both rod displacements and forces. The calculated forces are used to quantify the magnetomechanical effect in the transducer core, i.e., the stress-induced magnetization changes. This is done by considering a “law of approach” to the anhysteretic magnetization. The resulting model provides a representation of the bidirectional coupling between the magnetic and elastic states. It is demonstrated that the model accurately characterizes the magnetic hysteresis in the material, as well as the strains and forces output by the transducer under conditions typical of engineering applications.

AB - A number of computational methods have been proposed in the literature to design and synthesize feedback controls when the plant is modeled by nonlinear dynamics. However, it is not immediately clear which is the best method for a given problem; this may depend on the nature of the nonlinearities, size of the system, whether the amount of control used or time needed for the method is a concern, and other factors. In this paper, a comprehensive comparison study of five methods for the synthesis of nonlinear control systems is carried out. The performance of the methods on several test problems are studied, and some recommendations are made as to which feedback control method is best to use under various conditions.

AB - The issue of fairness has new prominence in multi-service networks where the diverse service characteristics can result in a very unfair resource allocation unless the issue is considered explicitly at the design stage. In this paper, we study the fairness issue of a Packet Routing Server (PRS) architecture based on the Dynamic synchronous Transfer Mode (DTM) access technology. DTM provides a dynamic bandwidth allocation scheme to support various types of telecommunications applications. However, this flexibility also promotes within DTM a lack of fairness concerning medium utilization as no enforcement scheme has been implemented in the DTM access technology. We demonstrate the unfairness of the DTM access scheme and provide resource reservation schemes to ensure that each type of traffic has its relatively fair share of the medium. Our results show that the dynamic resource reservation achieves a better medium utilization and a fair access of the resource in the DTM PRS.

AB - Various approaches to buffer size and management for output buffering in ATM switches supporting delay sensitive traffic are reviewed. Discrete worst case arrival and service functions are presented. Using this format, bounds are developed for buffer size under zero cell loss for leaky bucket constrained sources. Tight bounds are developed for the case of discrete arrival functions with fluid servers and fluid arrival functions with discrete servers. A bound on the buffer size is also proposed for the case of discrete arrival and service process. While this bound is not exact, the maximum gain that could be achieved by a tighter bound is bounded. In some cases it is possible to reduce the buffer size requirements through over allocation of link bandwidth. Feasibility conditions for this scenario are developed.

AB - Sharp fronts with rapid changes in fluid saturations over short distance and timescales often exist in multiphase flow in subsurface systems. Such highly nonlinear problems are notoriously difficult to solve, and standard solution approaches are often inefficient and unreliable. We summarize four existing and one new transformation method (IT2) for solving Richards'; equation within a common framework and compare performance for a range of medium properties and simulation conditions. The new IT2 transform is defined as a linear combination of volumetric water fraction of the aqueous phase and integrated hydraulic conductivity terms. We show that transformation methods can significantly improve solution efficiency and robustness compared to standard solution approaches; optimal transformation parameters depend upon auxiliary conditions, medium properties, and spatial and temporal discretization and are difficult to evaluate a priori; and IT2 compares favorably with existing transforms.

AB - We consider the problem of coordinating access to the various channels of a single-hop wavelength division multiplexing (WDM) network. We present a high performance reservation (HiPeR-ℓ) protocol specifically designed to overcome the potential inefficiencies of operating in environments with non-negligible processing, tuning, and propagation delays. HiPeR-ℓ differs from previous reservation protocols in that each control packet makes reservations for all data packets waiting in a node's queues, thus significantly reducing control overhead. Packets are scheduled for transmission using algorithms that can effectively mask the tuning times. HiPeR-ℓ also uses pipelining to mask processing times and propagation delays; parameter ℓ of the protocol is used to control the degree of pipelining. We use Markov chain theory to obtain a sufficient condition for the stability of the protocol. The stability condition provides insight into the factors affecting the operation of the protocol, such as the degree of load balancing across the various channels, and the quality of the scheduling algorithms. The analysis is fairly general, as it holds for MMBP-like arrival processes with any number of states, and for non-uniform destinations.

AB - We study a class of circuit-switched wavelength-routing networks with fixed or alternate routing and with random wavelength allocation. We present an iterative path decomposition algorithm to evaluate accurately and efficiently the blocking performance of such networks with and without wavelength converters. Our iterative algorithm analyzes the original network by decomposing it into single-path subsystems. These subsystems are analyzed in isolation, and the individual results are appropriately combined to obtain a solution for the overall network. To analyze individual subsystems, we first construct an exact Markov process that captures the behavior of a path in terms of wavelength use. We also obtain an approximate Markov process which has a closed-form solution that can be computed efficiently for short paths. We then develop an iterative algorithm to analyze approximately arbitrarily long paths. The path decomposition approach naturally captures the correlation of both link loads and link blocking events. Our algorithm represents a simple and computationally efficient solution to the difficult problem of computing call-blocking probabilities in wavelength-routing networks. We also demonstrate how our analytical techniques can be applied to gain insight into the problem of converter placement in wavelength-routing networks.

T2 - OPTIMAL CONTROL APPLICATIONS & METHODS
AB - We propose the use of proper orthogonal decomposition (POD) techniques as a reduced basis method for computation of feedback controls and compensators in a high-pressure chemical vapour deposition (HPCVD) reactor. In this paper, we present a proof-of-concept computational implementation of this method with a simplified growth example for III–V layers in which we implement Dirichlet boundary control of a dilute Group III reactant transported by convection and diffusion to an absorbing substrate with no reactions. We implement the model-based feedback control using a reduced order state estimator based on observations of the flux of reactant at the substrate centre. This is precisely the type of measurements available with current sensing technology. We demonstrate that the reduced order state estimator or compensator system is capable of substantial control authority when applied to a high-order system. In principle, these ideas can be extended to more general HPCVD control situations by including multiple species with gas-phase reactions and surface reactions.

T2 - APPLIED MATHEMATICS AND COMPUTATION
AB - Mathematical models of the human respiratory control system have been developed since 1940 to study a wide range of features of this complex system. The phenomena collectively referred to as periodic breathing (including Cheyne–Stokes respiration and apneustic breathing) have important medical implications. The hypothesis that periodic breathing is the result of delay in the feedback signals to the respiratory control system has been studied since the work of F.S. Grodins, J. Gray, A.I. Norins, R.W. Jones [J. Appl. Physiol. 1 (1954) 283–308] in the early 1950s. The purpose of this paper is to extend the model presented by M.C.K. Khoo, R.E. Kronauer, K.P. Strohl, A.S. Slutsky [J. Appl. Physiol. 53 (3) (1982) 644–659] in 1991 to include variable delay in the feedback control loop and to study the phenomena of periodic breathing and apnea as they occur during quiet sleep in infant sleep respiration at around 4 months of age. The nonlinear mathematical model consists of a feedback control system of five delay differential equations. Numerical simulations are performed to study instabilities in the control system and the occurrence of periodic breathing and apnea in the above case which is a time frame of high incidence of sudden infant death syndrome (SIDS).

T2 - IEEE TRANSACTIONS ON MAGNETICS
AB - This paper addresses the modeling of hysteresis in magnetostrictive transducers in the context of control applications that require an accurate characterization of the relation between input currents and strains output by the transducer. This relation typically exhibits significant nonlinearities and hysteresis because of inherent properties of magnetostrictive materials. The characterization considered here is based on the Jiles-Atherton mean field model for ferromagnetic hysteresis in combination with a quadratic moment rotation model for magnetostriction. As demonstrated by comparison with experimental data, the magnetization model very adequately quantifies both major and minor loops under various operating conditions. The combined model can then be used to accurately characterize output strains at moderate drive levels. The advantages of this model lie in the small number (six) of required parameters and its flexibility under a variety of operating conditions.

The work of several researchers has raised the following questions that led to research in a related direction: How must one go about partitioning the global coefficient matrix into blocks when the system is NCD and a two-level iterative solver (such as block SOR) is to be employed? Are block partitionings dictated by the NCD form of the stochastic one-step transition probability matrix necessarily superior to others? Is it worth investigating alternative partitionings? Better yet, for a fixed labeling and partitioning of the states, how does the performance of block SOR (or even that of point SOR) compare to the performance of the iterative aggregation-disaggregation (IAD) algorithm? Finally, is there any merit in using two-level iterative solvers when preconditioned Krylov subspace methods are available? We seek answers to these questions on a test suite of 13 Markov chains arising in 7 applications.

TI - An overview of relative sin Theta theorems for invariant subspaces of complex matrices
AU - Ipsen, ICF
T2 - JOURNAL OF COMPUTATIONAL AND APPLIED MATHEMATICS
AB - Relative perturbation bounds for invariant subspaces of complex matrices are reviewed, with emphasis on bounding the sines of the largest principal angle between two subspaces, i.e. sinΘ theorems. The goal is to provide intuition, as well as an idea for why the bounds hold and why they look the way they do. Relative bounds have the advantage of being better at exploiting structure in a perturbation than absolute bounds. Therefore the reaction of subspaces to relative perturbations can be different than to absolute perturbations. In particular, there are certain classes of relative perturbations to which subspaces of indefinite Hermitian matrices can be more sensitive than subspaces of definite matrices.

TI - The superposition of discrete-time Markov renewal processes with an application to statistical multiplexing of bursty traffic sources
AU - Elsayed, K. M. F.
AU - Perros, H. G.
T2 - Applied Mathematics and Computation
AB - The main contribution in this paper is the introduction of a methodology for approximately characterizing the superposition process of N>=2 arbitrary (and possibly heterogeneous) discrete-time Markov Renewal Processes (MRP). In this model, the superposition process is characterized by a MRP with a state space that grows exponentially with N. We consider an on/off traffic source model, where the distribution of the on and off periods is arbitrary, as a special case of the general MRP. Subsequently, a queueing model for a FIFO finite-buffer multiplexer with arbitrary on/off input sources is analyzed. We provide numerical results for testing the algorithms introduced in the paper. We also study the effect of some of the statistical properties of on/off input sources on the multiplexer's performance.

We also report on numerical experiments that show how an implementation of implicit filtering that exploits these new results can improve the performance of the algorithm.

AB - A cutting plane type algorithm for solving a system of infinitely many fuzzy inequalities with piecewise linear membership functions is proposed. In each iteration, we solve a finite nonlinear optimization problem and add one or two more constraints. The iterative process ends when an optimal solution is identified. A convergence proof, under some mild conditions, is given. An efficient implementation based on the concepts of constraint surrogation and maximum entropy is included.

T2 - IEEE TRANSACTIONS ON AUTOMATIC CONTROL
AB - Reduced-order models employing the Lagrange and popular proper orthogonal decomposition (POD) reduced-basis methods in numerical approximation and feedback control of systems are presented and numerically tested. The system under consideration is a thin cylindrical shell with surface-mounted piezoceramic actuators. Donnell-Mushtari equations, modified to include Kelvin-Voigt damping, are used to model the system dynamics. Basis functions constructed from Fourier polynomials tensored with cubic splines are employed in the Galerkin expansion of the full-order model. Reduced-basis elements are then formed from full order approximations of the exogenously excited shell taken at different time instances. Numerical examples illustrating the features of the reduced-basis methods are presented. As a first step toward investigating the behavior of the methods when implemented in physical systems, the use of reduced-order model feedback control gains in the full order model is considered and numerical examples are presented.

AB - When an activity-on-arc (AoA) project network is to be constructed, one typically seeks to minimize the number of dummy arcs. Recent investigations have shown, however, that the computational effort of many network-oriented project management techniques depends strongly on the so-called complexity index (CI) of a network. We show other justifications for minimizing the CI rather than the number of dummy arcs. We also present a polynomial time algorithm for constructing an AoA network with the minimum CI in the class of all AoA networks having the minimum number of nodes. © 2000 John Wiley & Sons, Inc.

AB - Advances in the engineering and design of advanced electro-optical materials require sensors and control strategies that allow tight control over thickness and composition of multilayered structures. In response to this demand, we developed and applied p-polarized reflectance (PR) for real-time optical characterization and control of heteroepitaxial GaP/GaInP growth under pulsed chemical beam epitaxy conditions. For closed-loop control, we applied nonlinear control algorithms (based on nonlinear Kalman filtering) that utilizes the PR signals to adjust the source flows involved in the heteroepitaxial growth of Ga1−xInxP on Si(001). A reduced order surface kinetics model has been formulated to establish the linkage between the surface reaction kinetic and its optical response. These data are linked to compute the compositional and thickness change per time unit, utilizing the monitored PR signals for validation. This allows the establishment of feedback control algorithms, able to control both the growth rate and composition of Ga1−xInxP heterostructures.

T2 - JOURNAL OF MANUFACTURING SYSTEMS
AB - Abstract A new micropositioning system based on the kinematic coupling principle is shown to offer advantages with respect to resolution, accuracy, precision, and position repeatability while maintaining full two-dimensional motion control. This new system is shown to have a mechanical amplification (leverage) that can allow up to several times increase in the effective positioning resolution of the actuators driving the kinematic coupling mechanism. However, the magnitude of the leverage is not homogeneous over the entire working envelope of the mechanism. Furthermore, in some areas, the magnitude of the leverage is shown to be very sensitive to perturbations in the design parameters. This paper provides a discussion of the parameter design analysis for the proposed system using a methodology based on design of experiments and nonlinear mathematical programming. Using an indicator developed for this purpose, a response surface for the mechanical advantage is obtained and optimal design areas are identified. More importantly, this analysis proves to be flexible enough in searching for the set of parameters that would achieve any particular target on the level of performance, while presenting the least sensitivity to manufacturing noise. This allows for manufacture of variations of the proposed mechanism within feasible manufacturing tolerances and costs. A case study is also presented as an illustration of one real application in manufacturing design. Additionally, potential areas of implementation, such as precision assembly and rapid prototyping, have been identified.

TI - An empirical approach to characterizing trunk muscle coactivation using simulation input modeling techniques
AU - Mirka, GA

AU - Wilson, , JR
T2 - JOURNAL OF BIOMECHANICS
AB - Accurately describing trunk muscle coactivation is fundamental to quantifying the spine reaction forces that occur during lifting tasks and has been the focus of a great deal of research in the spine biomechanics literature. One limitation of previous approaches has been a lack of consideration given to the variability in these coactivation strategies. The research presented in this paper is an empirical approach to quantifying and modeling trunk muscle coactivation using simulation input modeling techniques. Electromyographic (EMG) data were collected from 28 human subjects as they performed controlled trunk extension exertions. These exertions included isokinetic (10 and 45 degrees /s) and constant acceleration (50 degrees /s/s) trunk extensions in symmetric and asymmetric (30 degrees ) postures at two levels of trunk extension moment (30 and 80Nm). The EMG data were collected from the right and left pairs of the erector spinae, latissimus dorsi, rectus abdominis, external obliques and internal obliques. Each subject performed nine repetitions of each combination of independent variables. The data collected during these trials were used to develop marginal distributions of trunk muscle activity as well as a 10x10 correlation matrix that described how the muscles cooperated to produce these extension torques. These elements were then combined to generate multivariate distributions describing the coactivation of the trunk musculature. An analysis of these distributions revealed that increases in extension moment, extension velocity and sagittal flexion angle created increases in both the mean and the variance of the distributions of the muscular response, while increases in the rate of trunk extension acceleration decreased both the mean and variance of the distributions of activity across all muscles considered. Increases in trunk asymmetry created a decrease in mean of the ipsi-lateral erector spinae and an increase in the mean of all other muscles considered, but there was little change in the variance of these distributions as a function of asymmetry.

AB - This paper addresses the modeling of strains generated by magnetostrictive transducers in response to applied magnetic fields. The measured strains depend on both the rotation of moments within the material in response to the field and the elastic properties of the material. The magnetic behavior is characterized by considering the Jiles-Atherton mean field theory for ferromagnetic hysteresis in combination with a quadratic moment rotation model for magnetostriction. Elastic properties must be incorporated to account for the dynamics of the material as it vibrates. This is modeled by force balancing, which yields a wave equation with magnetostrictive inputs. The validity of the resulting transducer model is illustrated by comparison with experimental data.

AB - Intelligent transportation systems (ITS) represent a major initiative to improve roadway and travel conditions, not by building roads, but by drawing on new technologies in computing, sensing, and communications. However, these technologies are extremely complex and, while some demonstration projects have tested stand-alone systems, the broader architectural and standardization issues are still under development. The use of complex technologies in a safety-critical system such as ITS and at the scale envisioned requires a very careful study of the interaction between its various subsystems. This paper describes an approach for modeling the temporal aspects of ITS systems as well as their logical coordination using finite state verification tools. The approach is demonstrated by verifying safety properties of an automated traffic signal at a road intersection.

T2 - JOURNAL OF THE AIR & WASTE MANAGEMENT ASSOCIATION
AB - ABSTRACT Designing air quality management strategies is complicated by the difficulty in simultaneously considering large amounts of relevant data, sophisticated air quality models, competing design objectives, and unquantifiable issues. For many problems, mathematical optimization can be used to simplify the design process by identifying cost-effective solutions. Optimization applications for controlling nonlinearly reactive pollutants such as tropospheric ozone, however, have been lacking because of the difficulty in representing nonlinear chemistry in mathematical programming models. We discuss the use of genetic algorithms (GAs) as an alternative optimization approach for developing ozone control strategies. A GA formulation is described and demonstrated for an urban-scale ozone control problem in which controls are considered for thousands of pollutant sources simultaneously. A simple air quality model is integrated into the GA to represent ozone transport and chemistry. Variations of the GA formulation for multiobjective and chance-constrained optimization are also presented. The paper concludes with a discussion of the practicality of using more sophisticated, regulatory-scale air quality models with the GA. We anticipate that such an approach will be practical in the near term for supporting regulatory decision-making.

The third section analyzes an existing database to test for differences in cycle time and manufacturing performance between union and nonunion firms. Finally, we discuss the implications of the study for future operations strategy research and note how a different form of union-management relationships is beginning to evolve.

The design specifications are formulated as optimization constraints. The objective function is chosen to be the weight of the inductor. Optimization results are presented to demonstrate the efficiency of the proposed design methodology.

T2 - INVERSE PROBLEMS
AB - A variational approach for the robust inversion of linear smoothing operators is discussed. We employ and generalize the enhancement techniques based on BV- and Perona-Malik-type regularization methods. The problem is cast as the minimization of a cost functional consisting of a data fitting and a restoration energy criterion for multiscale objects consisting of edge, flat and grey regions. An iterative algorithm for finding the restored object that minimizes the cost functional is developed and analysed. It is based upon a fixed-point iteration combining a time-marching and successive substitution method for finding a solution to a quasi-elliptic partial differential equation. Global convergence is proved. Numerical examples illustrate the proposed approach.

TI - A revised simplex search procedure for stochastic simulation response surface optimization
AU - Humphrey, DG
AU - Wilson, , JR
T2 - INFORMS JOURNAL ON COMPUTING
AB - We develop a variant of the Nelder-Mead (NM) simplex search procedure for stochastic simulation optimization that is designed to avoid many of the weaknesses encumbering similar direct-search methods—in particular, excessive sensitivity to starting values, premature termination at a local optimum, lack of robustness against noisy responses, and computational inefficiency. The Revised Simplex Search (RSS) procedure consists of a three-phase application of the NM method in which: (a) the ending values for one phase become the starting values for the next phase; (b) the step size for the initial simplex (respectively, the shrink coefficient) decreases geometrically (respectively, increases linearly) over successive phases; and (c) the final estimated optimum is the best of the ending values for the three phases. To compare RSS versus NM and procedure RS+S9 due to Barton and Ivey, we summarize a simulation study based on four selected performance measures computed for six test problems that include additive white-noise error, with three levels of problem dimensionality and noise variability used in each problem. In the selected test problems, RSS yielded significantly more accurate estimates of the optimum than NM or RS+S9, and both RSS and RS+S9 required roughly four times as many function evaluations as NM.

AB - We analyze a multilayered queueing network that models a client-server system where clients and servers communicate via synchronous and asynchronous messages. The servers are organized in groups such that they form a multilayered hierarchical structure. The queueing network is approximately analyzed using a decomposition algorithm. Numerical tests show that the approximation algorithm has a good accuracy.

AU - Ito, K

AB - Newton's method for optimal control of highly nonlinear partial differential equations is analyzed using a 2-norm technique. We consider the case where neither the linearization of the equality constraint e characterizing the differential equation is surjective nor a second order sufficient optimality condition holds for the topology on which e is well defined. Such problems occur, for instance, in optimal control of semilinear elliptic equations or for parameter estimation problems. Despite the above mentioned difficulties, sufficient conditions for second order convergence are obtained.

AB - In this paper we consider a matrix-free path following algorithm for nonlinear parameter-dependent compact fixed point problems. We show that if these problems are discretized so that certain collective compactness and strong convergence properties hold, then this algorithm can follow smooth folds and capture simple bifurcations in a mesh-independent way.

T2 - LINEAR ALGEBRA AND ITS APPLICATIONS
AB - A closed form representation is given for the matrix S that sweeps out a single column. This includes the integer as well as the unitary and regular cases. The closed form is built up from the 2×2 case. The product rule for adjoints is used to show that the dual of this procedure is precisely the completion procedure, which completes a single column to a matrix B such that SB=BS=diagonal. This construction underlines the fact that the completion and elimination processes are complementary. By permuting rows suitably, the matrices may be assumed to be in lower Hessenberg form.

TI - Conditions for noise reduction and stable encoding of spatial structure by cortical neural networks
AU - Gutkin, BS
AU - Smith, CE
T2 - BIOLOGICAL CYBERNETICS
AB - Cortical circuits have been proposed to encode information by forming stable spatially structured attractors. Experimentally in the primary somatosensory cortex of the monkey, temporally invariant stimuli lead to spatially structured activity patterns. The purpose of this work is to study a recurrent cortical neural network model with lateral inhibition and examine what effect additive random noise has on the networks' ability to form stable spatially structured representations of the stimulus pattern. We show numerically that this network performs edge enhancement and forms statistically stationary, spatially structured responses when the lateral inhibition is of moderate strength. We then derive analytical conditions on the connectivity matrix that ensure stochasticly stable encoding of the stimulus spatial structure by the network. For stimuli whose strength falls in the near linear region of the sigmoid, we are able to give explicit conditions on the eigenvalues of the connection matrix. Finally, we prove that a network with a connection matrix, where the total excitation and inhibition impinging upon a neural unit are nearly balanced, will yield stable spatial attractor responses.

TI - Absolute and relative perturbation bounds for invariant subspaces of matrices
AU - Ipsen, ICF
T2 - LINEAR ALGEBRA AND ITS APPLICATIONS
AB - Absolute and relative perturbation bounds are derived for angles between invariant subspaces of complex square matrices, in the two-norm and in the Frobenius norm. The absolute bounds can be considered extensions of Davis and Kahan's sin θ theorem to general matrices and invariant subspaces of any dimension. The relative bounds are the most general relative bounds for invariant subspaces because they place no restrictions on the matrix or the perturbation. When the perturbed subspace has dimension one, the relative bound is implied by the absolute bound.
