One of the approaches for enhancing a business’ success among its competition is by satisfying its customers’ demands. Coordination across business units in a same company and different organizations has been used to achieve this goal. Supply-chain management focuses on how to integrate a series of organizations to achieve cooperation and improve the competitive capabilities of the whole chain. As for supply chain management, the distribution structure associated with a supply chain’s facilities and the flow of materials and goods among the supply chain system plays an important role in the supply chain’s performance. Thus, finding a way to design distribution networks has been catching plenty of attention over the years.
This paper deals with a three-echelon supply chain system with multi-period, multi-product and multi-shipping channels. The supply chain system is composed of multi-suppliers, multi-wholesalers and multi-retailers. In this system, the suppliers can satisfy retailers’ demands through the supplier-retailer channels or through the supplier-wholesaler-retailer channels. With the supplier-retailer channels, the suppliers directly ship products to retailers. With the supplier-wholesaler-retailer channels, the retailers’ demands are satisfied by wholesalers whose products are shipped from the suppliers. Most of the previous researches assume that the transportation cost is counted on the basis of per-unit transport charge. However, many practices also show that transportation cost may be counted on the basis of per-truck or per container charge. Under the per-truck transportation cost basis, this paper aims to minimize total shipping costs over a finite time planning period by determining the amount of each product, which should be shipped between two locations in each period of time. A constrained mixed integer programming model was formulated to develop the related decisions. Several examples are used to illustrate the insight into the problem. In addition, sensitivity analysis was also conducted to illustrate the impact of variation within the parameters on the computational results.
