Based On Re-ordering The Payment Of The Supply Chain Inventory Optimization Strategy Research

With the social progress and economic development, people's material demand is grow increasingly improved. So, the upgrading of goods must be faster, and the market competition is becoming fiercer. In order to open the market of the new products, the sellers often shoulder the risk of trade credit and allow buyers to pay at the reorder point. Payment at the reorder point is one special form of permissible delay in payments, and the sellers allow that the buyers can pick up the goods first and pay at the reorder point in accordance with requirements. Therefore, Permissible delay payment at the reorder point not only alleviates the buyers'financial pressure, but also reduces the buyers'risks, and then stimulates buyers to try to order the new products.The study of the optimal ordering strategy in the supply chain inventory under permissible delay payment at the reorder point, can rich the theory of the optimal control of the supply chain inventory, and has high values of theoretic and economic significance for the enterprises'inventory control and allocation of funds.This paper, based on permissible delay payment at the reorder point and viewed from the retailers'standpoint, respectively studies the optimal control of the inventory under three different assumptions of considering perishable products,multiple periods and uncertain demand. The main contents of the article are summarized as follows:(1) Consider the optimal inventory control strategy of perishable products under permissible delay payment at the reorder point, and build the retailers'optimal ordering model, and analyze quantitatively the models;(2) Consider the optimal inventory control strategy with multiple periods under permissible delay payment at the reorder point, and build the retailers'optimal ordering model, and analyze quantitatively the models;(3) Consider the optimal inventory control strategy with uncertain demands under permissible delay payment at the reorder point, and build the retailers'optimal ordering model, and analyze quantitatively the models;...
