An Inventory Model for Deteriorating Items with Conditional Trade Credit under Shortage

研究了库存短缺期内需求完全拖后下供应商给予零售商延期支付权限依赖于其订购量的易变质产品库存模型,其中零售商也允许顾客延期支付货款.根据实际把问题划分为6种子情形来构建相应的模型,并通过模型分析确定最优解存在与唯一性的条件.最后通过算例分析考察主要参数对库存系统的影响.

This paper studies the inventory model of deteriorating items under shortage,in which the supplier gives the retailer deferred payment authority depending on its order quantity,and the retailer also allows the customer to delay payment.According to the reality,the problem is divided into six sub-cases.After constructing the corresponding model,the conditions for the existence and uniqueness of the optimal solution are determined.Finally,the influence of the main parameters on the inventory system is analyzed by examples.
