部分延期付款且考虑非瞬间变质物品的库存模型

An inventory model for non-instantaneous deteriorating items with partial permissible delay in payments

针对具有一定保鲜期的物品,在零售商享有供应商提供的全额信用期而仅提供给其顾客部分信用期的假设条件下,建立非瞬间变质物品的库存模型。通过分析,给出了描述模型最优解的存在性和唯一性的三个定理,数值例子验证了模型的理论结果,重要参数的灵敏度分析给零售商决策订货策略提供理论建议。

Based on the items with some freshness-keeping period, an inventory model for non-instantaneous deteriorating i-tems will be established under the conditions of the assumption that the retailer can obtain a full credit period offered from the suppli-er, and offers a partial trade credit to his/ her customer. By analysis, three theorems are established to describe the optimal solution which is not only existence but also uniqueness. The numerical examples are given to illustrate all these theorems, and sensitive a-nalysis of the major parameters is provided for the theoretical suggestions of the retailer ordering strategy.
