Evaluation of mixed‐model U‐line operational designs

Yunsook Hong, John K. Visich, Peter A. Pinto, Basheer M. Khumawala

International Transactions in Operational Research > 20 > 6 > 917 - 936

Often in lean manufacturing, multiple products are produced in U‐shaped manufacturing cells to simultaneously achieve product variety and production efficiency. We examine two design issues for mixed‐model U‐lines: work rules (a first‐come‐first‐serve rule and a crossover‐and‐return rule) and inventory flow choices (direct flow and buffered flow). Simulation results indicated that throughput and labor...

B2C Mass Customization in the Classroom

John K. Visich, Qiannong Gu, Basheer M. Khumawala

Decision Sciences Journal of Innovative Education > 10 > 4 > 521 - 545

The purpose of this article is to describe an internet‐based mass customization assignment in Operations Management/Supply Chain Management classes where students utilize the Web site of a company that offers a customized product. Students evaluate the user interface, judge the value proposition of the product they demonstrate, and discuss issues of product design, process design and scheduling, inventory...

An empirical comparison of Tabu Search, Simulated Annealing, and Genetic Algorithms for facilities location problems

Marvin A. Arostegui, Sukran N. Kadipasaoglu, Basheer M. Khumawala

International Journal of Production Economics > 2006 > 103 > 2 > 742-754

Algorithms to solve Facility Location Problems (FLP) optimally suffer from combinatorial explosion and resources required to solve such problems repeatedly as required in practical applications become prohibitive. In these cases heuristic methods are the only viable alternative. We compare the relative performance of Tabu Search (TS), Simulated Annealing (SA) and Genetic Algorithms (GA) on various...

A simulation study of focused cellular manufacturing as an alternative batch-processing layout

Fahad Al-Mubarak, Cem Canel, Basheer M. Khumawala

International Journal of Production Economics > 2003 > 83 > 2 > 123-138

This paper is aimed at studying focused cellular manufacturing (FCM). We define FCM as a layout scheme that groups components by end-items and forms cells of machines to fabricate and assemble end-items. It is not classified as a cellular manufacturing layout since it does not attempt to take advantage of process similarities. It also is not classified as a flow shop since there are no machines dedicated...

An algorithm for the capacitated, multi-commodity multi-period facility location problem

Cem Canel, Basheer M. Khumawala, Japhett Law, Anthony Loh

Computers and Operations Research > 2001 > 28 > 5 > 411-427

There are substantial number of exact and heuristic solution methods proposed for solving the facilities location problems. This paper develops an algorithm to solve the capacitated, multi-commodity, multi-period (dynamic), multi-stage facility location problem. The literature on such composite facility location problem is still sparse. The proposed algorithm consists of two parts: in the first part...

An improved algorithm for solving a multi-period facility location problem

Amir M. Hormozi, Basheer M. Khumawala

Location Science > 1996 > 4 > 4 > 286

An exact algorithm for the multi-period facility location problem is proposed that efficiently integrates mixed-integer and dynamic programming methods. Two simplification procedures are introduced to reduce the size of the general multi-period facility location problem substantially. Because the proposed algorithm utilizes dynamic programming to obtain the optimal sequence over the entire planning...

An efficient heuristic procedure for the single-item, discrete lot sizing problem

Cem Canel, Basheer M. Khumawala, Japhet S. Law

International Journal of Production Economics > 1996 > 43 > 2-3 > 139-148

This study looks at the single-item discrete lot sizing problem with backorders. Most of the studies in the literature on lot sizing problems do not allow for backordering. This paper modifies some of the heuristic rules developed originally for the facility location problems and applies them to the lot sizing problem. The heuristic rules are tested and evaluated for their efficiency. The findings...
