| Inventory-transportation integrated optimization problem integrates inventory control problem and transportation problem into a system and use a objective function to depiction. From the research and application status, optimization of these two aspects to make for improving logistics system efficiency and saving costs. As early as mid-1980, overseas scholars had begun to study inventory-transportation integrated optimization problem. The model and algorithm had a number of studies, but the studies were rare in the domestic.FPP is a very effective method to study tactical level of inventory-transportation integrated optimization problem. The so-called FPP is dividing customs into different regions in advance, and assigning a vehicle to each region. Costs functions of FPP have its own unique structure characterization which makes model and algorithm design simpler. FPP has been widely used. It not only can be applied to VMI, but also to the non-integrated supply chain. Owing to the case of suppliers and retailers for different enterprises in our country, they do not take account of cooperating with other enterprises in order to maximize their own profits. Therefore, the studying inventory-transportation integrated optimization problem of non-integrated supply chain has more practical significance.Overall, this paper has done some research in the following two aspects:The first part analyses FPP's applying on VMI allowed out of stock. We determine a distribution plan for supplier and give the costs function of the whole system and an algorithm of solving the costs function.The second part analyses FPP's applying on non-integrated supply chain disallowed out of stock. We determine a distribution plan for supplier and give the profits function of the whole system and an algorithm of solving the profits function. Moreover, in order to ensure that suppler and retailers can accept this plan, we put forward a pricing strategy to realize the whole supply chain coordination. |
