摘　　要：研究了考虑保鲜技术投资成本、允许缺货且缺货量部分延迟订购的非即时腐败品的库存和定价联合决策问题.首先,在保鲜期小于库存持有周期和保鲜期大于等于库存持有周期两种情况下分别构建了相应的库存和定价联合决策模型,证明并得到模型解的存在性和唯一性条件.最后,通过两种情况下的算例展示了模型的有效性,并对重要参数的灵敏度进行了分析.结果表明:保鲜技术投资和保鲜期都对定价和订购策略以及利润具有重要影响,与库存水平相关的保鲜技术投资的增加将使服务水平和利润先增加后减少,而产品保鲜期的延长使服务水平和平均利润均有显著提高.The inventory and pricing problem of non-instantaneously deteriorating products incorporating preservation technology investment and partial backlogging was studied in this paper. First, inventorypricing models were established both in the cases of the inventory period longer than the shelf-time and the inventory period shorter than the shelf-time. Then, the conditions under which the unique solution existed were obtained. Finally, some numerical examples were taken to illustrate the effectiveness of the model and some sensitive analyses on the main parameters were conducted. The results show that parameters, such as preservation technology investment and shelf-time, could exert significant effects on the inventorypricing strategy as well as the average profit. Specifically, the increase of the preservation technology related to the inventory could first raise the service rate and then reduce it, as is the case for the average profit. The increase in shelf-time has positive effects on both rate service and average total profit.
