基于商业信用的供应链数量折扣协调策略

一个供应商和一个零售商构成的供应链中,由于供应商向零售商提供商业信用,会影响供应商与零售商各自的目标利润及供应链的总利润.为了解决这一问题,实现零售商和供应商对供应链总收益的合理分配,建立了随机需求下基于商业信用的数量折扣契约协调模型.分析了一定信用条件下数量折扣策略在供应链的收益分配及实现协调方面的作用,推导出实现供应链协调的最优契约参数.最后通过数值算例说明了所得结论的正确性.

Quantity Discount Policy Based on Trade Credit for Supply Chain Coordination

In a supply chain from a supplier to a retailer, the trade credit the former offered to the latter is possible to affect individually their target profit hence the total profit of the supply chain. To solve the problem, the total income from the supply chain should be shared rationally between the supplier and retailer, thus developing a contractual coordination model for quantity discount based on trade credit in random demand. Analyzing the effect of quantity discount policy on income sharing and coordination on the basis of a certain trade credit, the optimal contractual parameters are deduced to realize the coordination of the whole supply chain. A numerical example is given to demonstrate the correctness of the conclusion drawn from the coordination model and relevant analysis.
