    摘要:

    研究变质品的订购、定价和保鲜技术投资联合决策问题.假设产品需求同时受价格和库存水平的影响,系统不允许缺货并放松期末库存水平为零的约束,零售商拥有有限的货架空间或存储空间,同时考虑零售商可以通过投资保鲜技术减低产品的变质率,以平均利润最大化为目标构建库存水平影响需求下变质品的订购、定价和保鲜技术投资联合决策模型.首先证明最优策略的存在性和唯一性,并给出零售商建立期末库存的条件;然后利用最优解的相关性质设计一个求解模型的多阶段迭代算法;最后通过具体算例验证展示模型和算法的可行性和实用性,并完成相关参数的敏感性分析,获得一定的管理启示.

    Abstract:

    This paper studies a joint ordering, pricing and preservation investment decision problem for perishable items. It is assumed that the demand rate is dependent on price and inventory level simultaneously, shortages are not allowed and the restriction of zero ending-inventory is relaxed. And meanwhile considering that the deterioration rate can be controlled by employing a certain preservation technology and the retailer has limited shelf space or storage space. The inventory model of the joint ordering, pricing and preservation investment decision for deteriorating items with inventory-level-dependent demand is proposed with the goal of maximizing the retailer's average profit. First, it is proved that the optimal policy not only exits but also unique, and we also provide the conditions for retailer to build up inventory. Then, an iterative algorithm is designed to find the optimal solution according to the relevant properties of the model. Finally, the numerical example is given to illustrate the feasibility and practicability of the model and algorithm, and the sensitivity analysis of relevant parameters is carried out and some managerial insights are derived.
