AB - Abstract This article discusses the routing and wavelength assignment (RWA) problem in optical networks employing wavelength division multiplexing (WDM) technology. Two variants of the problem are studied: static RWA, whereby the traffic requirements are known in advance, and dynamic RWA in which connection requests arrive in some random fashion. Both point‐to‐point and multicast traffic demands are considered.

AB - We consider the problem of traffic grooming in WDM path, star, and tree networks. Traffic grooming is a variant of the well-known logical topology design problem, and is concerned with the development of techniques for combining low speed traffic components onto high speed channels in order to minimize network cost. Our contribution is two-fold. In the first part of the paper we settle the complexity of traffic grooming in path and star networks by proving that a number of variants of the problem are computationally hard. Since routing and wavelength assignment in these two topologies is trivial, these results demonstrate that traffic grooming is itself an inherently difficult problem. Our results have implications for ring and other more general topologies, which we explore. In the second part, we design practical grooming algorithms with provable properties. Specifically, for all three topologies, we obtain a series of lower and upper bounds which are increasingly tighter but have considerably higher computational requirements; the series of upper bounds form an algorithm for the traffic grooming problem with strong performance guarantees. We also present corresponding heuristics with good performance. Our work is a first step towards a formal and systematic approach to the grooming problem in general topologies that builds upon results and algorithms for more elementary networks.

AU - Aytug, H.

T2 - International Journal of Production Research
AB - In automated manufacturing systems, deadlock avoidance policies guarantee deadlock-free operation while performance controllers, such as dispatching rules, attempt to achieve performance thresholds. In an automated system, dispatching rules must work within the constraints imposed by the deadlock avoidance policy in order to assure continuing system operation, and thus, the deadlock avoidance logic defines the decision space over which the dispatching rule can work. This paper investigates the interactions that arise between deadlock avoidance flexibility and the effectiveness of dispatching rules in achieving good system performance. Two major findings are that the positive effects of intelligent dispatching are highly influenced by the flexibility of the deadlock avoidance policy, and that a naÿve dispatching rule can sometimes achieve better system performance under an inflexible deadlock avoidance policy.

AB - Work centre-based decomposition approaches, especially variants of the Shifting Bottleneck algorithm, have been very successful in solving job-shop-scheduling problems. These methods decompose the problem into subproblems involving a single work centre (usually a single machine), which they solve sequentially. We propose new measures of subproblem criticality and show via computational experiments that several of these provide solutions comparable in quality with those obtained from previous work in substantially less central processing unit time.

AU - Li, Zhilin
AU - Lin, Xiaobiao

T2 - Methods and Applications of Analysis
AB - The weighted minimal surface problem in heterogeneous media is studied in this paper. The solution to the weighted minimal surface problem is continuous but the derivatives have a jump across the interface where the medium property is discontinuous. The jump condition of the derivatives derived in this paper generalized the Snell's law in geometric optics to weighted minimal surfaces of co-dimension one in any dimensional space. A numerical method based on the gradient flow and the maximum principal preserving immersed interface method is developed to solve this nonlinear elliptic interface problem with jump conditions. Numerical computations are presented to verify both the analysis and the numerical algorithm. 1. Introduction. The minimal surface problem, that is, the problem of finding the surface of the least area among all surfaces having fixed boundary data, has been extensively studied. A recent workshop on minimal surfaces presented the latest re- search on minimal surface applications in chemistry and biology (5). Many phenomena that occur in nature relate to this problem which has been a motivation for devel- oping new mathematical theories and techniques to solve the problem analytically and numerically. Minimal surfaces were shown to be important in various chemical micro-structures and their corresponding phase transitions (5). Computer graphics and image analysis use minimal surfaces frequently for boundary detection, and to construct surfaces that are visually appealing (2), (15). Soap films and other mem- branes passing through a fixed boundary provide mechanical examples of minimal surfaces (14). A related concept is the idea of capillary surfaces, which result from surface tension in liquids. These surfaces are closely related to minimal surfaces (6). For a precise mathematical description of the minimal surface problem we refer, for example, to the classical treatises (7) and (16). The minimal surface problem can be described in two different ways, using the parametric or the non-parametric formulation. In the non-parametric setting the candidate surfaces are graphs of functions, while in the parametric setting the surfaces are treated as boundaries of sets (7). The former is usually seen in more physically- based treatments of the problem, whereas the later provides an excellent framework for the mathematical analysis of minimal surfaces. When the medium is homogeneous, the energy density at each point is constant, and therefore the surface energy is equivalent to the surface area. This is the standard minimal surface problem. In this paper, we consider the weighted minimal surface problem in a heterogeneous medium in which the energy density is piecewise smooth. For example this is the case for capillary interfaces in porous media or composite materials. In particular we derive a jump condition for the weighted minimal surface at the interface between two different media. The jump condition can be regarded as a generalized Snell's law which describes the refraction of minimal surfaces instead of light rays in geometric optics.

AB - The Malcolm Baldrige National Quality Award (MBNQA) has become a model for the deployment of quality programmes. While the framework underlying the award has been used extensively by organisations, both for award and self-assessment purposes, little empirical evidence exists regarding its validity as a predictor of organisational performance. This research presents a structural equation model that explicitly tests the relationships between strategic and operational quality planning implied by the framework, and their impact on performance. Results support the theory underlying the Baldrige award. Specifically, the strategic quality planning process, mediated by the effective use of information and analysis, is the driver of operational quality planning. Positive business results are the outcome of this planning process. Results also show that customer and market focus is a crucial input to strategic quality planning, the commitment of senior leadership is critical in securing a customer and market focus, and operational level business processes are driven by a strategic commitment to human resource management.

AB - Recently an approach for multi-model identification and failure detection in the presence of bounded energy noise over finite time intervals has been introduced. This approach involved offline computation of an auxiliary signal and online application of a hyperplane test. This approach has several advantages but as presented, observation over the full time interval was required before a decision could be made. In this paper it is shown how to modify this approach to permit early decision making with the hyperplane test.

AB - Development of the next generation of RF devices is in progress with research on sheet beam and multiple beam devices on-going at several institutions. Analysis of inherently three dimensional devices requires a new set of analytical tools to model the electromagnetic fields and the behavior of electron and ion beams. Existing codes, such as HFSS and MAFIA, are widely used to model the electromagnetic fields in these devices, but there is a need for simple, accurate, and efficient codes to model the behavior of charged particles in 3D geometries and fields. Calabazas Creek Research, Inc. (CCR) is funded by the U.S. Department of Energy to develop a finite element, charged particle, analysis code suitable for the next generation of RF devices. The principle feature of the new program is adaptive meshing, which removes the burden for mesh generation from the user and assigns responsibility to field solver and particle pusher routines.

T2 - Third IEEE International Vacuum Electronics Conference
AB - Calabazas Creek Research, Inc. is funded by the U.S. Department of Energy to develop an advanced charged particle code using adaptive meshing. One of the tasks in that program is to model secondary and reflected electrons in collectors. The Center for Research in Scientific Computing (CRSC) received a subcontract to develop a 3D Monte Carlo technique for modeling these electrons. Taking into account the energy and direction of an incident electron, as well as the atomic number, atomic mass and density of the solid, the program calculates a statistically reasonable path for the electron through the solid via Monte Carlo techniques. When applied to large numbers of electrons, the algorithm provides statistically accurate results. The success of the effort resulted in a stand-alone code that could be use to investigate the effect of various materials and coatings to reduce the emission and there by achieve higher depressed collector efficiencies.

T2 - Lecture Notes in Computer Science
AB - We are developing an approach for P2P information systems, where the peers are modelled as autonomous agents. Agents provide services or give referrals to one another to help find trustworthy services. We consider the important case of information services that can be cached. Agents request information services through high-level queries, not by describing specific objects as in caching in traditional distributed systems. Moreover, the agents autonomously decide whom to contact for a service, whom to provide a service or referral, whether to follow a referral and whether to cache a service. Thus the information system itself evolves as agents learn about each other and the contents of the caches of the agents change. We study here the effect of caching on service location and on the information system itself. Our main results are that, (1) even with a small cache, agents can locate services more easily; (2) since the agents that cache services can act like service providers, a small number of initial service providers are enough to serve the information needs of the consumers; and (3) agents benefit from being neighbours with others who have similar interests.

AB - While the traditional data envelopment analysis (DEA) requires precise input and output data, available data is usually imprecise and vague. “Fuzzy DEA” integrates the concept of fuzzy set theory with the traditional DEA by representing imprecise and vague data with fuzzy sets. In this paper, a credibility approach is proposed as a way to solve the fuzzy DEA model. The approach transforms a fuzzy DEA model into a well-defined credibility programming model, in which fuzzy variables are replaced by “expected credits” in terms of credibility measures. It is shown that when the membership functions of fuzzy data are trapezoidal, the credibility programming model becomes a linear programming model. Numerical examples are given to illustrate the proposed approach and results are compared with those obtained with alternative approaches.

AB - The virtual factory is a job shop scheduling tool that was developed at NC State. It has been found to provide near-optimal solutions to industrial-sized problems in seconds. Recently, the virtual factory was expanded to include interfactory transportation operations, which enabled the detailed scheduling of entire multifactory manufacturing supply chains. Separately, a rolling horizon procedure was developed to test the virtual factory for single factory problems. This procedure allowed us to more accurately predict how the virtual factory would perform in industry. Consequently, the rolling horizon procedure was extended to multifactory settings to gauge industrial performance and eliminate transient effects found in previous multifactory experimentation. Experimental results, under a variety of different scenarios, indicate that the virtual factory also performs well in multifactory, rolling horizon settings.

AB - Scheduling any complicated job shop becomes increasingly more difficult when the cycle time is reduced. We discuss the implementation of a simulation-based scheduling system that properly schedules parts in a two-plant operation. The system has allowed the company to reduce the cycle time by at least a week from two/three weeks to one/two weeks. As part of the project, the generation of the input data needed to drive the simulation is also discussed since this data did not exist in the correct form. The model generation, simulation development, and experimentation will be discussed. The system that is described is currently being used to generate the schedules.

T2 - Lecture Notes in Computer Science
AB - Commitments are a powerful representation for modeling multiagent interactions. Previous approaches have considered the semantics of commitments and how to check compliance with them. However, these approaches do not capture some of the subtleties that arise in real-life applications, e.g., e-commerce, where contracts and institutions have implicit temporal references. The present paper develops a rich representation for the temporal content of commitments. This enables us to capture realistic contracts and institutions rigorously, and avoid subtle ambiguities. Consequently, this approach enables us to reason about whether and when exactly a commitment is satisfied or breached and whether it is or ever becomes unenforceable.

T2 - Lecture Notes in Computer Science
AB - Protocols for multiagent interaction need to be flexible because of the open and dynamic nature of multiagent systems. Such protocols cannot be modeled adequately via finite state machines (FSMs) as FSM representations lead to rigid protocols. We propose a commitment-based formalism called Nonmonotonic Commitment Machines (NCMs) for representing multiagent interaction protocols. In this approach, we give semantics to states and actions in a protocol in terms of commitments. Protocols represented as NCMs afford the agent flexibility in interactions with other agents. In particular, situations in protocols when nonmonotonic reasoning is required can be efficiently represented in NCMs.

AB - A method has been developed to estimate single cotton fiber tensile properties from load-elongation curves of slack fiber bundles. The method is applied to bundle load- elongation curves from HVI tests to estimate the averages of fiber breaking strength, elongation, and crimp. The estimated values are compared with single fiber tensile properties obtained from a Mantis® single fiber tester.

TI - The future of agent communication
AU - Singh, Munindar P.
T2 - Lecture Notes in Computer Science
AB - This short note discusses trends in computing environments where agent communication will have the most value. The main emerging trend in computing is toward openness, that is, toward large systems with dynamically changing, autonomous, heterogeneous components. This trend speaks the end of architecture in the traditional sense. More importantly, it emphasizes on declaratively specified interactions, that is, arms-length relationships, among independent components. Agents and multiagent systems provide key abstractions for computing in open settings. In particular, agent communications will be a key means for structuring distributed computations.

AB - Abstract Let ( α n , β n ) denote the Gauss–Newton estimator of the parameter (α,β) in the autoregression model Zij=αZi−1,j+βZi,j−1−αβZi−1,j−1+eij. It is shown in an earlier paper that when α=β=1, {n 3/2 ( α n −α, β n −β)} converges in distribution to a bivariate normal random vector. A two-parameter strong martingale convergence theorem is employed here to prove that n r ( α n −α, β n −β)→ 0 almost surely when r 3 2 .

AB - In this paper, we investigate the universal approximation property of Radial Basis Function (RBF) networks. We show that RBFs are not required to be integrable for the REF networks to be universal approximators. Instead, RBF networks can uniformly approximate any continuous function on a compact set provided that the radial basis activation function is continuous almost everywhere, locally essentially bounded, and not a polynomial. The approximation in L(p)(micro)(1 < or = p < infinity) space is also discussed. Some experimental results are reported to illustrate our findings.

AB - The National Spherical Torus Experiment (NSTX) is a low aspect-ratio fusion research facility whose research goal is to make a determination of the attractiveness of the spherical torus concept in the areas of high-β stability, confinement, current drive, and divertor physics. Remarkable progress was made in extending the operational regime of the device in FY 2002. In brief, βt of 34% and βN of 6.5 were achieved. H-mode became the main operational regime, and energy confinement exceeded conventional aspect-ratio tokamak scalings. Heating was demonstrated with the radiofrequency antenna, and signatures of current drive were observed. Current initiation with coaxial helicity injection produced discharges of 400 kA, and first measurements of divertor heat flux profiles in H-mode were made.

T2 - Journal of Intelligent Material Systems and Structures
AB - This paper provides a theory for quantifying the hysteresis and constitutive nonlinearities inherent to piezoceramic compounds through a combination of free energy analysis and stochastic homogenization techniques. In the first step of the model development, Helmholtz and Gibbs free energy relations are constructed at the lattice or domain level to quantify the relation between the field and polarization in homogeneous, single crystal compounds which exhibit uniform effective fields. The effects of material nonhomogeneities, polycrystallinity, and variable effective fields are subsequently incorporated through the assumption that certain physical parameters, including the local coercive and effective fields, are randomly distributed and hence manifestations of stochastic density functions associated with the material. Stochastic homogenization in this manner provides low-order macroscopic models with effective parameters that can be correlated with physical properties of the data. This facilitates the identification of parameters for model construction, model updating to accommodate changing operating conditions, and control design utilizing model-based inverse compensators. Attributes of the model, including the guaranteed closure of biased minor loops in quasistatic drive regimes, are illustrated through examples.

AU - Jackson, LE

T2 - IEEE TRANSACTIONS ON PARALLEL AND DISTRIBUTED SYSTEMS
AB - We simplify the periodic tasks scheduling problem by making a trade off between processor load and computational complexity. A set N of periodic tasks, each characterized by its density /spl rho//sub i/, contains n possibly unique values of /spl rho//sub i/. We transform N through a process called quantization, in which each /spl rho/i /spl isin/ N is mapped onto a service level s/sub j/ /spl isin/ L, where |L| = l /spl Lt/ n and /spl rho//sub i/ /spl les/ s/sub j/, (this second condition differentiates this problem from the p-median problem on the real line). We define the periodic task quantization problem with deterministic input (PTQ-D) and present an optimal polynomial time dynamic programming solution. We also introduce the problem PTQ-S (with stochastic input) and present an optimal solution. We examine, in a simulation study, the trade off penalty of excess processor load needed to service the set of quantized tasks over the original set, and find that, through quantization onto as few as 15 or 20 service levels, no more than 5 percent processor load is required above the amount requested. Finally, we demonstrate that the scheduling of a set of periodic tasks is greatly simplified through quantization and we present a fast online algorithm that schedules quantized periodic tasks.

TI - Delay-based congestion avoidance for TCP
AU - Martin, J

AU - Rhee, I
T2 - IEEE-ACM TRANSACTIONS ON NETWORKING
AB - The set of TCP congestion control algorithms associated with TCP/Reno (e.g., slow-start and congestion avoidance) have been crucial to ensuring the stability of the Internet. Algorithms such as TCP/NewReno (which has been deployed) and TCP/Vegas (which has not been deployed) represent incrementally deployable enhancements to TCP as they have been shown to improve a TCP connection's throughput without degrading performance to competing flows. Our research focuses on delay-based congestion avoidance algorithms (DCA), like TCP/Vegas, which attempt to utilize the congestion information contained in packet round-trip time (RTT) samples. Through measurement and simulation, we show evidence suggesting that a single deployment of DCA (i.e., a TCP connection enhanced with a DCA algorithm) is not a viable enhancement to TCP over high-speed paths. We define several performance metrics that quantify the level of correlation between packet loss and RTT. Based on our measurement analysis we find that although there is useful congestion information contained within RTT samples, the level of correlation between an increase in RTT and packet loss is not strong enough to allow a TCP/Sender to reliably improve throughput. While DCA is able to reduce the packet loss rate experienced by a connection, in its attempts to avoid packet loss, the algorithm will react unnecessarily to RTT variation that is not associated with packet loss. The result is degraded throughput as compared to a similar flow that does not support DCA.

AU - Petersen, KJ
AU - Handfield, RB
AU - Ragatz, GL
T2 - JOURNAL OF PRODUCT INNOVATION MANAGEMENT
AB - In many industries, firms are looking for ways to cut concept-to-customer development time, to improve quality, and to reduce the cost of new products. One approach shown to be successful in Japanese organizations involves the integration of material suppliers early in the new product development cycle. This involvement may range from simple consultation with suppliers on design ideas to making suppliers fully responsible for the design of components or systems they will supply. While prior research shows the benefit of using this approach, execution remains a problem. The processes for identifying and integrating suppliers into the new product development (NPD) process in North American organizations are not understood well. This problem is compounded by the fact that design team members often are reluctant to listen to the technology and cost ideas made by suppliers in new product development efforts. We suggest a model of the key activities required for successful supplier integration into NPD projects, based on case studies with 17 Japanese and American manufacturing organizations. The model is validated using data from a survey of purchasing executives in global corporations with at least one successful and one unsuccessful supplier integration experience. The results suggest that (1) increased knowledge of a supplier is more likely to result in greater information sharing and involvement of the supplier in the product development process; (2) sharing of technology information results in higher levels of supplier involvement and improved outcomes; (3) supplier involvement on teams generally results in a higher achievement of NPD team goals; (4) in cases when technology uncertainty is present, suppliers and buyers are more likely to share information on NPD teams; and (5) the problems associated with technology uncertainty can be mitigated by greater use of technology sharing and direct supplier participation on new product development teams. A supplier’s participation as a true member of a new product development team seems to result in the highest level of benefits, especially in cases when a technology is in its formative stages.

AB - Semi–smooth Newton methods are analyzed for a class of variational inequalities in infinite dimensions. It is shown that they are equivalent to certain active set strategies. Global and local super-linear convergence are proved. To overcome the phenomenon of finite speed of propagation of discretized problems a penalty version is used as the basis for a continuation procedure to speed up convergence. The choice of the penalty parameter can be made on the basis of an L∞ estimate for the penalized solutions. Unilateral as well as bilateral problems are considered.

We apply an eight-tuple extended finite state machine (EFSM) model to formally specify the protocol. Using the EFSM model, we define the communication between a source client node and a destination client node through an ingress and one or multiple intermediate switches. We work on on-the-fly and persistent unicast connections. The communication between the EFSMs is handled through messages.

T2 - Lecture Notes in Computer Science
AB - Web services have been gathering an increasing amount of attention lately. The raison d'etre of Web services is that we compose them to create new services. For Web services to be effectively composed, however, requires that they be trustworthy and in fact be trusted by their users and other collaborating services. In our conceptual scheme, principals interact as autonomous peers to provide services to one another. Trust is captured as a composite relationship between the trusted and the trusting principal. Principals help each other discover and locate trustworthy services and weed out untrustworthy players. The interactions of the principals combined with the needs of different applications induce interesting structures on the network.We apply multiagent systems techniques to model interactions among the principals.
By varying the requirements of different applications, the needs of different principals, the existence of special principals such as trusted authorities, and the mechanisms underlying the interactions, we draw attention to a variety of important settings where Web services would be composed. One, leading to superior methods through which trust can be evolved and managed in realistic service-composition settings. Two, studying the relationships between aspects of trust forWeb services and the evolution of Web structure.

AB - In this paper, numerical methods are proposed for some interface problems in polar or Cartesian coordinates. The new methods are based on a formulation that transforms the interface problem with a nonsmooth or discontinuous solution into a problem with a smooth solution. The new formulation leads to a simple second order finite difference scheme for the partial differential equation and a new interpolation scheme for the normal derivative of the solution. In conjunction with the fast immersed interface method, a fast solver has been developed for the interface problems with a piecewise constant but a discontinuous coefficient using the new formulation in a polar coordinate system.

AB - Current software development practices are often “business-driven” and therefore tend to encourage testing approaches that reduce verification and validation activities to shorten schedules. In this chapter, we focus on efficiency of testing and resulting software quality (reliability) in such an environment. We use a resource constrained testing model to analyze data from several projects. Our results indicate that in a practical resource constrained environment there is little room for improving testing during the actual process. Furthermore, there is likely to be considerable variability in the quality of testing, within a testing phase, that may stem from a variety of sources such as the human element, software development practices and the structure of the software itself. However, it is interesting to note that there are experimental results showing that testing efficiency can be improved over longer periods of time through process improvement, and that software quality does appear to be positively correlated with an increase in the average testing efficiency that stems from process improvements.

Based on a simple, single-machine dynamic scheduling problem, state dependent scheduling rules for the single machine problem are developed and tested using Markov Decision Processes. Then, a generalized scheduling policy for the job shop problem is established based on a characterization of the optimal policy. The policy is combined with a 'forecasting' mechanism to utilize global shop floor information for local dispatching decisions. Computational results show that performance is significantly better than that of existing alternative policies.

Each inclusion region has a diameter related to the singular values of a restriction of the matrix to a subspace and dependent on either an eigenvector condition number or the departure of the matrix from normality. The inclusion regions are optimal for normal matrices. Similar considerations lead to inclusion bounds based on relative distances expressed analogously in terms of appropriately defined generalized singular values.

T2 - IEE PROCEEDINGS-CONTROL THEORY AND APPLICATIONS
AB - The analysis and state-feedback synthesis problems for linear parameter-varying systems with parameter-varying time delays are addressed. It is assumed that the state-space data and the time delays are dependent on parameters that are measurable in real-time and vary in a compact set with bounded variation rates. We explore the stability, L2 gain performance and L2 - to- L∞ gain performance for these systems using parameter-dependent Lyapunov functionals. In addition, the design of parameter-dependent state-feedback controllers that guarantee stability and desired induced norm performance are examined. Both analysis and synthesis conditions are formulated in terms of linear matrix inequalities that can be solved via efficient interior-point algorithms.

TI - Distributed control for interconnected linear parameter dependent systems
AU - Wu, F
T2 - IEE PROCEEDINGS-CONTROL THEORY AND APPLICATIONS
AB - Stability analysis and performance control problems for a class of interconnected parameter-dependent systems with linear fractional parameter dependency are considered. The time and spatially varying parameters are assumed measurable in real-time for controller use. The distributed controller inherits the spatial structure of the plant, which is implementable through parallel computation. The stability of the interconnected parameter-dependent systems is established using a distributed Lyapunov function. Moreover, the synthesis condition of distributed parameter-dependent control gain is formulated as a convex optimisation in the form of a linear matrix inequality. An explicit distributed controller formula is also provided by exploiting the connection between the continuous and the discrete interconnected system descriptions.

TI - A note on unifying absolute and relative perturbation bounds
AU - Ipsen, ICF
T2 - LINEAR ALGEBRA AND ITS APPLICATIONS
AB - Perturbation bounds for invariant subspaces and eigenvalues of complex matrices are presented that lead to absolute as well as a large class of relative bounds. In particular it is shown that absolute bounds (such as those by Davis and Kahan, Bauer and Fike, and Hoffman and Wielandt) and some relative bounds are special cases of `universal' bounds. As a consequence, we obtain a new relative bound for subspaces of normal matrices, which contains a deviation of the matrix from (positive-) definiteness. We also investigate how row scaling affects eigenvalues and their sensitivity to perturbations, and we illustrate how the departure from normality can affect the condition number (with respect to inversion) of the scaled eigenvectors.

AB - New finite element methods based on Cartesian triangulations are presented for two dimensional elliptic interface problems involving discontinuities in the coefficients. The triangulations in these methods do not need to fit the interfaces. The basis functions in these methods are constructed to satisfy the interface jump conditions either exactly or approximately. Both non-conforming and conforming finite element spaces are considered. Corresponding interpolation functions are proved to be second order accurate in the maximum norm. The conforming finite element method has been shown to be convergent. With Cartesian triangulations, these new methods can be used as finite difference methods. Numerical examples are provided to support the methods and the theoretical analysis.

T2 - Fuzzy Sets and Systems
AB - Evaluating the performance of activities or organizations by traditional data envelopment analysis (DEA) models requires crisp input/output data. However, in real-world problems inputs and outputs are often imprecise. This paper develops DEA models using imprecise data represented by fuzzy sets (i.e., “fuzzy DEA” models). It is shown that fuzzy DEA models take the form of fuzzy linear programming which typically are solved with the aid of some methods to rank fuzzy sets. As an alternative, a possibility approach is introduced in which constraints are treated as fuzzy events. The approach transforms fuzzy DEA models into possibility DEA models by using possibility measures of fuzzy events (fuzzy constraints). We show that for the special case, in which fuzzy membership functions of fuzzy data are of trapezoidal types, possibility DEA models become linear programming models. A numerical experiment is used to illustrate the approach and compare the results with those obtained with alternative approaches.

AU - Wu, F.
AU - Jaramillo, J. J.
T2 - Asian Journal of Control
AB - In this paper, a frequency-weighted optimal H∞ model reduction problem for linear time-invariant (LTI) systems is considered. The objective of this class of model reduction problems is to minimize H∞ norm of the frequency-weighted truncation error between a given LTI system and its lower order approximation. A necessary and sufficient solvability condition is derived in terms of LMIs with one extra coupling rank constraint, which generally leads to a non-convex feasibility problem. Moreover, it has been shown that the reduced-order model is stable when both stable input and output weights are included, and its state-space data are given explicitly by the solution of the feasibility problem. An efficient model reduction scheme based on cone complementarity algorithm (CCA) is proposed to solve the non-convex conditions involving rank constraint.

T2 - EUROPEAN JOURNAL OF OPERATIONAL RESEARCH
AB - Abstract The purpose of this paper is to present a flexible genetic-based framework for solving the multi-criteria weighted matching problem (mc-WMP). In the first part of this paper, we design a genetic-based framework for solving the ordinary weighted matching problem. We present an extensive analysis of the quality of the results and introduce a methodology for tuning its parameters. In the second part, we develop a modified genetic-based algorithm for solving the mc-WMP. The algorithm generates a significant and representative portion of the Pareto optimal set. To assess the performance of the algorithm, we conduct computational experiments with two and three criteria. The potential of the proposed algorithm is demonstrated by comparing to a multi-objective simulated annealing algorithm.
