Research On The Inventory Control Policy Based On Reversed Logistics

Global economic and the fast development productive forces bring the enormous social product and people's material life have been satisfied massively .However, there exists long time game between them and backflow product processing of commodities, as well as has overdevelopment to the renewable resources' and to the environmental protection pressure. At present, to realize the economical sustainable development, various governments have established the backflow product processing laws and regulations policy to their own countries. As an outstanding management idea, reverse logistics has already become the emerging research area in recent years.The inventory control and the management are an important subsystem in logistics management. The holding cost of stock has occupied 20% to 40% of the product cost. The repaired returned products of reverse logistics can be the necessary additional item to the inventory Therefore, it is a big economic significance to study stock problems of reverse logistics. Under the above background, this article proposed inventory control theory based on the reverse logistics, by establishment reverse logistics inventory control model, then formulation effective management strategy for reverse logistics.According to the product demand and the backflow characteristic, this article divides the reverse logistics inventory control model into the deterministic model and the stochastic pattern model. In the deterministic model situation, We discusses situations of permit stock out and non-permit stock out, proposed mathematical models that have certain theory and the use value; In the stochastic pattern model situation, the article discuss the single-cyclical and the multi-cyclical stock order strategy. To improve single-cyclical inventory control based on the classical newsboy model; because the multi-cycle inventory model is the typical multi-policy-making question, this article applies the dynamic programming theory to carry on the solution to it, analyzes the different parameter to the influence of inventory cost. The research indicated that the models which established have the great use value to the realization.
