关于信用期内含缺陷产品EOQ模型

Economic Order Quantity Model with Imperfect Items and Trade Credit

考虑到在实际中供应链上游供应商提供给下游零售商的信用支付期通常为一个订货周期,建立了缺陷率服从一定分布的缺陷产品在信用支付策略下的最优订货批量模型.模型中允许缺货发生并且以最大期望利润为目标函数,通过分析得到模型最优解.最后给出仿真实验,并且分析了模型参数变化对最优解的影响.

Taking into account that the supply chain upstream suppliers usually give a credit payment order cycle to the downstream retailers in practice the economic order quantity （EOQ） model with defective rate obey a certain distribution was studied in this paper,and the EOQ model is in the trade credit period that of the retailer offer to his/her customers. By assuming that shortage is completely backordered,the model of inventory with the objective of the maximum expected profit was developed. At last, numerical example is presented and the effects of parameters are also given to illustrate the proposed model.
