A Bi-criteria Distance Reduction Approach for Simple Plant Location Problem

Workspace location decision is considered as a complex problem that requires a detail evaluation and analysis approach. The determination process of a location position should be based on various factors and criteria in order to take into consideration all the requirements of the supply chain that are influencing the efficiency and the general performance of the workspace. The role of the workspace can be viewed differently according to the decision-maker preferences and the nature of business area. In this project, we propose an innovative resolution approach for the single workspace location problem in a polygonal area. Our objective is to locate the facility so as to minimize the total distance between the facility, the customers and the suppliers. Our bi-criteria approach is based on the consideration of the distance and the importance factor of each customer and supplier. We used the A-distance measurement and the aggregation methods to represent the real traveled distance as part of the mathematical modeling of the problem. The aim of the study is to determine the workspace location coordinates that put forward the economic, commercial, and ecological efficiency of the supply chain.
