Abstract: Considering the effect of the preservation technology investment on product deterioration rate, a joint decision-making model for pricing, inventory and preservation investment has been developed for non-instantaneous deterioration items with price-dependent demand, aiming to maximize the average total profit per unit time. Based on the proof of the existence and uniqueness of the optimal solutions, two iterative algorithms are designed to solve the inventory decision model for two cases, where the replenishment occurs before and after deterioration, respectively, and the characteristics of the global optimal solution are further analyzed to simplify the solving process. Finally, the application of the model is demonstrated by numerical examples. The experimental results show that the investment of preservation technology is beneficial to reduce the loss caused by product deterioration and increase the total profit of the retailer. Moreover, the investment of preservation technology is more effective for products with higher deterioration rate.

Key words: non-instantaneous deteriorating items, preservation technology investment, pricing, inventory

摘要： 考虑保存技术投资对产品变质率的影响，构建了一类需求取决于价格的非立即变质品定价、库存和保存投资联合决策模型，目标是使平均总利润最大。在证明最优解存在性和唯一性的基础上，分别设计出迭代算法以求解变质前补货和变质后补货两种情况下的库存决策模型，并进一步分析全局最优解的特征，以简化求解步骤。最后，通过具体的数值案例展示模型的应用性。实验结果表明：零售商通过采用保存技术的投资有利于减少产品变质带来的损失，增加零售商的总利润；并且投资保存技术对于变质率高的产品更加有效。
