含残次品及价格折扣的双层延期支付策略研究

考虑含有部分残次品的三级供应链模型。在该模型中,供应商和零售商均采用延期支付策略,供应商为先支付一部分货款的零售商提供一个价格折扣。基于极大化零售商的利润建立了零售商的库存模型,同时给出了寻求最优补货决策和最佳货款支付方式的算法,并通过数值算例来说明模型的有效性。

The Study for Two Levels of Trade Credit Policy with Defective Items and Price Discount

In this paper,a three-level supply chain model containing a portion of defective items is considered.In this model,both the supplier and the retailer adopt trade credit policy.The supplier offers a price discount for those retailers who pay part of payments for goods first.Based on maximizing the re-tailer's profit,the retailer's inventory model is developed.Meanwhile,an algorithm to find the optimal re-plenishment decision and the best way of delay in payments are presented.At last,numerical examples are made to illustrate the validity of this model.
