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

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

Abstract 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 branch and bound is used to generate a list of candidate solutions for each period and then dynamic programming is used to find the optimal sequence of configurations over the multi-period planning horizon. Bounds commonly known in the location literature as delta and omega are used extensively to effectively reduce the total number of transshipment subproblems needed to be solved. The proposed algorithm is particularly effective when the facility reopening and closing costs are relatively significant in the multi-period problem. An example problem is included to illustrate the proposed solution procedure. Scope and purpose The literature on the facilities location problem is extensive with a wide variety of solution methods for addressing these problems. In this paper, an algorithm is proposed 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. We develop the decision rules to be employed in this algorithm and describe their rationale. Through an illustrative example, we offer insights on the solution algorithm and how it can be implemented to solve the composite problem.

A mixed‐integer programming approach for the international facilities location problem

Cem Canel; Basheer M. Khumawala

For many years, facilities location problems have attracted a great deal of attention in the literature. As a result, there is now a variety of methods for solving these problems. However, due to the recent interest, little research is found relating to the issues concerning international facilities location problems. Furthermore, in spite of the extensive modelling work done on facilities location, little modelling research exists on location problems. Provides a capacitated multi‐period, 0‐1 mixed integer programming formulation for the international facilities location problem and discusses its applications to an actual company case. This application is carried out to demonstrate not only how the model can be applied in practice but also to show its potential benefits when compared to other methods.

Just‐in‐time is not just for manufacturing: a service perspective

Cem Canel; Drew Rosen; Elizabeth A. Anderson

Confronting the challenges of global competition, companies are focusing more on the needs of customers to improve product quality and customer service. The manufacturing sector has long been aware of the need to reduce waste as a means to reduce costs and improve product quality. Just‐in‐time (JIT), the formalized process of waste reduction, has achieved a strong foothold in the manufacturing sector. The service sector, however, has not been as quick to recognize the benefits of JIT. Services are much like manufacturing in that both employ processes that add value to the basic inputs used to create the end product. JIT focuses on the process, not the product. It can, therefore, be applied to any process within manufacturing or service operations. This paper provides a framework for applying JIT to processes in the service sector, with the goal of investigating how JIT principles can be implemented in services.

Underlying dimensions of business location decisions

Fahri Karakaya; Cem Canel

Most previous studies dealing with business site selection decisions have been theoretical and mainly concerned with cost factors. There are many variables other than cost, some of which are qualitative and intangible in nature. This study attempts to provide empirical evidence on the importance of cost and other location‐related variables. The 84 fastest‐growing businesses in New England and New York were surveyed utilizing 27 variables associated with location decisions. Most of the 27 variables are industry‐specific and their importance varies from industry to industry. Factor analysis, using principal component extraction method and varimax rotation showed that there are six underlying dimensions considered in business site selection decisions. Cities and towns can benefit from utilizing the findings of this type of research in attracting new businesses and preventing the existing businesses from leaving for other locations.

International facilities location: A heuristic procedure for the dynamic uncapacitated problem

Cem Canel; Basheer M. Khumawala

It is now well known that most major companies no longer operate in a single market. To penetrate global markets and obtain their benefits, companies are under tremendous pressure to reduce the price of their products, and thus their production and material costs. When a foreign location is used, the components of a product are produced there and final assembly takes place either at the foreign location or at the parent domestic plant. This paper first presents the issues related to international facilities location (IFL) problems, and provides the framework required to deal with such problems. It then presents a heuristic algorithm for solving the IFL problem. Extensive computational experience was gained by solving a variety of IFL problems of different sizes.

Modeling global facility location decisions: integrating marketing and manufacturing decisions

Cem Canel; Sidhartha R. Das

Rapid changes in today’s global markets are forcing businesses to re‐examine and improve the ways they compete. Integration of facility location decisions in global marketing and manufacturing strategies provides an important means for firms to compete in global markets. This paper proposes that manufacturing utility can be related to marketing utility through facility location decisions. Consequently, it presents a mathematical model for global facility location that integrates marketing and manufacturing decisions in a global context. It also presents a four‐stage evolutionary model that can guide managers in making global facility location decisions.

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

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

Abstract 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 to individual operations and the machines are not arranged in a series. The results indicate that the FCM scheme has a batching advantage (i.e., it has to wait less time to batch components before assemble). This advantage dominated the balanced machine utilization benefit of the job shop (JS) layout scheme. The JS was only able to overcome the batching advantage when there were small batch sizes or large setup time magnitudes.

Designing service processes: a design factor based process model

Sidhartha R. Das; Cem Canel

The challenge of increased service quality and productivity in the service industry cannot be met by simply adapting the present product-oriented operations management techniques to a people-oriented endeavour. We must develop a new perspective, one that encompasses the uniqueness of service organisations while capturing the knowledge gained from manufacturing over the last hundred years. This paper explores how service processes can be designed from this new perspective. It identifies six major design factors that are to be used when designing service processes and discusses how they are related. It also describes a process model that uses these design factors for designing service processes.

Focused cellular manufacturing: an alternative to cellular manufacturing

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

This paper is aimed at comparing cellular manufacturing with focused cellular manufacturing. We define focused cellular manufacturing 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 to individual operations and the machines are not arranged in a series. In addition, this research includes batching and assemble times in its criteria which few researchers in this area have done. The results indicate that the focused cellular manufacturing scheme has a batching advantage. This advantage out‐weighed the set‐up time reduction advantage of the cellular manufacturing scheme for average end‐item completion times and average work‐in‐process inventory levels. The cellular manufacturing scheme overcame the batching advantage only when there were small batch sizes or large set‐up time magnitudes.
