Demand seasonality in the U.S. Imported Beer industry is common. The financial cycles of the past decade brought some extreme fluctuations to industry demand, which was trending upward. This research extends previous work in this area by comparing seasonal forecasting models for two time periods: 1999–2007 and 1999–2012. The previous study (Kros & Keller, 2010) examined the 1999–2007 time frame while this study extends their model using the new data. Models are developed within Excel and include a simple yearly model, a semi-annual model, a quarterly model, and a monthly model. The results of the models are compared and a discussion of each model’s efficacy is provided. While, the models did do a good job forecasting U.S. Import Beer sales from 1999 to 2007 the economic downturn starting in 2007 was deleterious to some models continued efficacy. When the data from the downturn is accounted for it is concluded that the seasonal models presented are doing an overall good job of forecasting U.S. Import Beer Sales and assisting managers in shorter time frame forecasting.}, booktitle={Advances in Business and Management Forecasting}, publisher={Emerald Group Publishing Limited}, author={Kros, John F. and Rowe, W.

This work investigates a regional hospital, which has an affiliated low-acuity emergency department (ED) facility that currently struggles to meet its service level goal (85% of its patients should be in the room in 60 minutes or less). A capability analysis using data from existing processes at this facility revealed that with the current processes and current level of resources, the facility is not capable of meeting existing service level goal. A simulation was developed to examine multiple alternatives that could improve patient flow at the facility. A set of scenarios were created that modified one or more of the resources such as doctors, nurses, and rooms by changing their schedules or their quantities. The impact of the response variables related to the facility’s service level goal was recorded for each scenario. Based on the results of the simulation, recommendations to the facility for alternative ways to schedule and allocate its resources in order to meet its current service level goal were given.}, booktitle={Applications of Management Science}, publisher={Emerald Group Publishing Limited}, author={Keeling, Kellie B. and Brown, Evelyn and Kros, John F.}, year={2013}, month={Nov}, pages={219–229} }

In this study, we investigate how appropriate these grouping quality measures are in determining cell formations that optimize factory performance.

These cell formations are then simulated to determine their impact on various factory measures, such as flow time, wait time, throughput, and machine utilization, among others. Results indicate that it is not always the case that a ''more efficient'' machine/part cell formation leads to significant changes or improvements in factory measures over a ''less efficient'' cell formation.

The scarce bandwidth is not only consumed by placing and receiving calls on a portable, but by performing routine control functions to ensure universal service and increased quality of service.

The registration area planning problem attempts to achieve this with minimal impact on the network's bandwidth. In this paper, we develop a grouping genetic algorithm to efficiently solve the registration area planning problem. The problem is NP-complete, therefore the literature has concentrated on heuristics to find good solutions in an acceptable time. The goal of registration area planning is to group wireless network cells into contiguous areas to minimize location update costs subject to paging bound and preset constraints. Therefore, the registration area planning problem is a grouping problem and grouping genetic algorithms, which have been shown to be a useful tool in solving these types of problems, are an applicable solution methodology. The proposed grouping genetic algorithm, GGARAP, has been extensively tested.

A code-division multiple-access network where the base stations are connected to the central station by fiber has been proposed to reduce the installation costs. To reduce the coordination costs and the number of handoffs, sectorization (grouping) of the cells is suggested. We propose a dynamic sectorization of the cells, depending on the current sectorization and the time-varying traffic.

We formalize the material ordering and cutting problem faced by this industry and propose a grouping genetic algorithm, called CPGEA, for efficiently controlling the relevant costs. We test the quality of CPGEA in various ways. Three sets of simulated problems with known optimal solutions are solved using CPGEA, and the gap between its solutions and optimal solutions is measured. The same problem sets are also solved with an expert system and a multi-start greedy heuristic. CPGEA solutions are found to be consistently lower cost than the competing methods. The difference in solution quality is most pronounced for difficult problems requiring multiple identical plates in the optimal solution. CPGEA is also tested using data from actual construction projects of a company faced with this problem. Since an optimal solution for the problems is not available, a lower bound is created. For the historical problems tested, the average percent difference between CPGEA solutions and the lower bound is 0.67%. To put this performance in context, the results of solving these problems with an expert system and using experienced engineers is also reported. Of these three methods, CPGEA achieves the best performance and the human experts the worst performance.}, number={4}, journal={Computers & Industrial Engineering}, publisher={Elsevier BV}, author={Hung, Chang-Yu and Sumichrast, Robert T. and Brown, Evelyn C.}, year={2003}, month={Apr}, pages={651–672} }

In particular, the crossover operator for a GGA involves the development of heuristic procedures to restore group membership to any entities that may have been displaced by preceding actions of the operator. In this paper, we present evidence that the success of a GGA is heavily dependent on the replacement heuristic used as a part of the crossover operator. We demonstrate this by comparing the performance of a GGA that uses a naive replacement heuristic (GGA0) to a GGA that includes an intelligent replacement heuristic (GGACF). We evaluate both the naive and intelligent approaches by applying each of the two GGAs to a well-known grouping problem, the machine-part cell formation problem. The algorithms are tested on problems from the literature as well as randomly generated problems. Using two measures of effectiveness, grouping efficiency and grouping efficacy, our tests demonstrate that adding intelligence to the replacement heuristic enhances the performance of a GGA, particularly on the larger problems tested. Since the intelligence of the replacement heuristic is highly dependent on the particular grouping problem being solved, our research brings into question the robustness of the GGA. Scope and purpose Our research investigates the significance of the replacement heuristic used as a part of the crossover operator in a grouping genetic algorithm (GGA). We test two GGAs and compare their replacement heuristics using test problems from the well-known machine-part cell formation domain. The purpose of our research is three-fold. First, we compare and contrast the GGA with standard GA to improve understanding of how they differ in problem representation and operation. Second, we provide evidence that GGA is limited not only to problems where the objective is to form groups, but also to problems where it is practical to incorporate a substantial amount of problem-specific information. Third, we estimate the impact that the GGA replacement heuristic has on performance. Results indicate that GGA performs up to 40% worse when problem-specific knowledge is not incorporated into the replacement heuristic.}, number={11}, journal={Computers & Operations Research}, publisher={Elsevier BV}, author={Brown, Evelyn C. and Sumichrast, Robert T.}, year={2003}, month={Sep}, pages={1575–1593} }
