A Study On Inventory Control Of Seasonal Goods In Supply Chain

With the development of network technology, human society economic development enters a new age. In the Twentieth Century because of electronic commerce promotion, the trend of logistics in China appears an unprecedented upsurge. The generation and application of logistics brings great commerce benefits for national economy and enterprise production management. It is shown that logistics modernization has been the lever of economic development in China.Global economy and manufacturing integrated impels competitions among enterprises to become more and more aggravating. These competitions have been changed among from all single enterprises to supply chains which are composed of a series of upstream and downstream enterprises. So the supply chain management becomes the corn content of the enterprise management. And inventory management is the corn content of the supply chain management. The loss brought by overstock and shortage cost can weaken profit ability and market competitiveness of the enterprise greatly. It can restrict not only the cost of the node enterprise but also the comprehensive cost, whole performance and competitive advantage of the whole supply chain. Therefore, the corn problem the enterprises is how to get the balance of production and sale, how to establish an effective inventory control system and how to realize the spatial value and time value of the products.This paper demonstrates a new management mode in supply chain-Vender Management Inventory (VMI) and studies on the process of seasonal goods. First, this paper introduces some theories about supply chain management and inventory. Second, it builds a model with seasonal exponential smoothing and shows the model is feasible to forecast demand by empirical analysis. Third, according to some characteristics about the seasonal goods, it puts forward an optimal inventory replenishment model between wholesaler and retailer by building two-echelon inventory system. Then the paper demonstrates this model can greatly reduce the logistic costs of all partners in supply chain, increase profit, implement all partners win-win, and then enhance competitive ability of the whole supply chain. Last, the paper assumes some modes and methods about multi-item seasonal goods. To sum up, all of above show that VMI can not only realize the balance between inventory controlling and supply-demand properly but also meet the requirements of customers who are upstream and downstream partners in the supply chain. So, it makes the upstream suppliers have the right to make some decision about supply-demand of goods for the downstream partners. Basing on the cooperative partnership, this management model is focusing on information sharing, revenue sharing, and risk sharing. It realizes an integrated environment among all partners in supply chain which can promote the supply chain smoothly.
