Penentuan lokasi gudang dan rute pendistribusian menggunakan integer programming

Abstract

Distributing is one of important activities in a company. The efficiency of distribution costs can increase company profits. In this context the problems faced by the company are to reduce distribution costs including the determination of the warehouse location and the distribution route. In this paper, two mathematical models are studied. Those are the model for determining the warehouse location and the distribution route. Models are formulated in term of integer programming. In implementation, we considera logistic company which has 1 distribution center, 2 warehouses, 3 suppliers, 40 customers, and 24 trucks with different capacities. The company plans to establish at most 3 new warehouses. It is demonstrated that, by using the models, two new locations of warehouse are recommended and an optimal distribution route is provided.
