One of the mainly caused is each customer zone, which consist of several demand points, served by more than one warehouses. This policy causes high delivery cost and also makes what called marketing conflict. The objectives of this problem solving is determining number, location and distribution coverage of warehouse that could minimizing total logistic cost. Total logistic cost consist of delivery cost from warehouse to customer zone, storage and operation cost at warehouse and transportation cost from plant to warehouse. The best solution is achieved using heuristic approach and optimized using integer linear programming by examining the best configuration network offering the least total logistic cost.
