RESEARCH ON COORDINATION OF SUPPLY CHAIN CONTRACT TO TWO-STAGE SALES PROCESS OF PRODUCTS

摘要

In this paper, we study the two-stage sales problem of a class of short-life-cycle products, introduce supply chain contracts into the basic profit model, and analyze the impact of supply chain contracts on the coordination of two-stage sales of products. The sales process of commodities can be divided into three situations: centralized decision-making, decentralized independent decision-making and contract decision-making. The goal of supply chain coordination is to maximize the profit of the supply chain in centralized decision-making, and the interests of each member should not be damaged when achieving this goal. On the basis of previous studies, this paper introduces wholesale price variation parameters into supply chain contracts, and analyses the effects of repurchase contracts, price subsidy contracts and joint contracts on the sales process. By solving the model, the solution set related to system cost structure, contract parameters and market demand distribution is obtained.
