需求依赖努力水平的农产品供应链期权契约优化

针对供应商和零售商组成的农产品供应链,研究市场需求受到努力水平影响的农产品供应链协调问题.由于双重边际效应,分散式供应链中的最优生产数量低于集中式供应链的情况,零售商努力水平也相对较低.引入期权契约时,在零售商主导期权契约的供应链中,研究得到零售商的最优初始订货量和最优期权价格,以及供应商的最优生产数量,实现供应链协调.数值分析证实了期权契约有助于提高零售商的努力水平以及整个供应链的利润.

Agricultural Product Supply Chain Optimization under Option Contract with Effort Level Dependent Demand

For an agricultural product supply chain consist of a supplier and a retailer;we study the agricultural product supply chain coordination in a market environment when demand is affected by the effort level.Owing to the double marginalization,the optimal production quantity in the decentralized supply chain is lower than that in the centralized system,and the effort level is also lower.When introducing the option contract,in the supply chain where the retailer is dominant in the option contract,we get the retailer's optimal initial order quantity and the optimal option price,as well as the supplier's optimal production quantity.The result shows that coordination can be reached.The data analysis verifies that the option contract can improve the effort level as well as the whole supply chain profit.
