二层信用策略下部分延期支付的多物品EPQ模型

An EPQ Model for Multi-item Under two Levels of Trade Credit Policy and Partial Permissible Delay in Payments

基于二层信用策略的EPQ模型中,绝大多数的模型是考虑单物品的情形,由于需求的多样性,多物品库存模型越来越受库存管理者的关注.在二层信用条件下,假设零售商仅提供给它的顾客部分货款延期支付,建立了部分延期支付的多物品EPQ模型,并证明了模型存在唯一的最优解,最后给出数值例子验证模型的有效性.

The EPQ model based on two levels of trade credit policy,the vast majority of the model is considered the single item.Because of the diversity of demand,the inventory model for multi-item is being more and more inventory management attention.We assume that the retailer is only provided to the customer part of his/her payment deferred payment under the condition of two levels of trade credit.An EPQ model for multi-item under retailer partial deferred payment is established.It proves that the model has a unique optimal solution.Finally,numerical examples are given to illustrate the validity of this model.
