Study Of The Inventory Control In Supply Chain Management

In recent years, with the development of global economy and the enlargement of enterprise, supply chain management has attracted many scholars at home and abroad. Supply chain management is the oversight of materials, information, and finances as they move in a process from supplier to manufacturer to wholesaler to retailer to consumer. Supply chain management involves coordinating and integrating these flows both within and among companies. It is said that the ultimate goal of any effective supply chain management is to reduce inventory. Three chapters are included in this thesis.In the first chapter, we describe the research situations of the supply chain management, basic background of the inventory management, some useful knowl-edge and the main results obtained in this thesis.In the second chapter, we consider a two-echelon inventory lot-sizing prob-lem with multi-mode shipments between the upper and the lower echelons, and each mode has a fixed set-up cost structure. We present an optimal polynomial algorithm for this problem. The aim is to determine the replenishment amounts for distribution center and retailer respectively in order to minimize the trans-portation cost and inventory cost.In the third chapter, we consider an inventory model for non-instantaneous deteriorating items with special stock-dependent demand and partial backlogging. The backlogging rate is an non-increasing function of the waiting time for the next replenishment. An optimal replenishment policy for this model is established. The solution procedure is illustrated with some numerical examples.
