The Research Of Inventory Control In Sales Network Based On Radio Frequency Identiifcation

Modern inventory involves in large variety of products. The inventory process management and structure is extremely complex, and often refers to large geographical span. Therefore, the request for accurate and timely information becomes much stricter than ever before. How to set appropriate stocks to reduce inventory costs, without affecting the normal production and customer service, is the first problem that the managers must consider in inventory management. How to build inventory to meet market demand is the important issues for managers to improve and optimize the enterprise supply chain.Nowadays, the consumption of perishable goods in China increase quickly. Because of the deteriorating and short life time characteristics of deteriorating items, it is important to research the inventory management for deteriorating items for the purpose of regulating demand and supply. In view of the reasons stated, this paper focuses on the deteriorating items, combine with the inventory control theory under RFID and bar technology to formulates two kinds of inventory models of perishable goods, assuming demand is deterministic while time is continuous. The paper also presents the methods of solving the above models and their respective optimal replenishment strategies, build the newsboy models of adoption of RFID with inaccurate information and also analyze the influence of inventory inaccuracy and demand uncertainty on the system.In this paper, we introduce the concepts and related theories of inventory, RFID, perishable goods. Also, we make a literature review about them, point out the problems of the study and give my ideas about the research. There are three main parts in this study as following.According to the types of demand and analysis of perishable products,the thesis formulates two kinds of inventory control strategies taking into account dynamic inventory levels for the perishable product. The inventory costs include: purchase cost, inventory holding costs and perishable costs, then establish inventory control models of costs and revenue, and solve it. Then, this paper makes a comparison among two models by a numerical example, and analyzes sensitivity of the parameters. Comparing the profit models with RFID and the one without RFID.Finally, the inventory is defined and classified. The newsboy models are built with RFID and without RFID. In this paper, we analyze the impacts of inventory inaccuracy, demand uncertainty and other factors on models, get the break-even RFID tag cost. The impacts of inventory inaccuracy and demand uncertainty on customer service level are also analyzed.
