摘　　要：针对一条由1个占主导地位的制造商和多个供应商组成的二级供应链,考虑供应商生产过程的衰退,建立了生产批量与产品质量之间的关系.综合考虑制造商的采购成本和售后期望损失成本,并根据供应商决策其经济生产批量时考虑因素的不同,建立2种订单分配模型.该模型的约束条件包括供应商产能约束和供应商关系维持约束.通过遗传算法得到2种模型的优化解,并对2种模型进行分析比较.最后,基于联合决策模型对单一供应商的定价策略变动进行了灵敏度分析.This paper established the relationship between production batch and product quality considering suppliers＇ production process shift in a two-stage supply chain consisting of one dominant manufacturer and several suppliers.Based on the different considerations of deciding suppliers＇ economic production quantity,and thinking of the purchase cost and expected after-sale loss cost together,the paper builds two kinds of order allocation models.The constraint conditions include supplier capacity constraints and supplier relationship maintenance constraints.Then the models＇ superior solutions are obtained through the genetic algorithm.Finally,the paper gives the sensitivity analysis of pricing strategy changes of a single supplier based on the joint decision model.
