考虑保鲜技术投资的多品补货与定价联合决策

Joint Replenishment and Pricing Decision of Multi-item Considering the Investment of Fresh Preservation Technology

生鲜产品易损耗、不易存储,保质保鲜是生鲜冷链运作的典型特征和基本要求。对冷链流通企业来说,采用不同保鲜技术会影响库存商品的保鲜周期,而保鲜周期与商品定价息息相关,最终反映到企业利润上。现实决策中,多种产品的差异性又加剧了决策复杂度。在多品情景下,保鲜技术投入与产品收益之间的平衡关系有待分析。因此,在综合考虑多品补货、库存商品非立即变质周期和定价的基础上,通过引入保鲜技术投资参数,构建了基于保鲜技术投资的生鲜品的联合补货与定价模型,提出了一种自适应差分进化算法(adaptive differential evolution algorithm,ADEA)对模型进行求解,验证了算法的有效性,并对参数进行了敏感度分析。实验结果表明,合理的保鲜技术投资有利于减少产品变质损失,使企业获得更高的利润。

There are great challenges in storing fresh products with quality fast deterioration features.Thus,quality retention and fresh preservation are typical characteristics and basic requirements in routine fresh cold chain operations.For cold chain logistics enterprises,the adoption of different preservation technologies would affect the preservation cycle of fresh items.In contrast,the length disturbance of the preservation cycle is closely related to item pricing,which would ultimately be reflected in the profits of enterprises.In practical operations,various items are usually replenished simultaneously.It aggravates the complexity of decision-making.Therefore,it is urgent to initiate novel research on balancing the investment cost in fresh preservation technology and the pricing of fresh items.Under such a background,by comprehensively considering the multi-item replenishment and non-immediate deterioration cycle,a joint replenishment and pricing model was constructed to investigate the preservation technology investment effects via the introduced investment parameters.An adaptive differential evolution algorithm(ADEA)was proposed to solve the model.The effectiveness of ADEA was tested and the sensitivities of the parameters were analyzed.The results show that reasonable investment in preservation technology can reduce the loss of product deterioration and help enterprises gain more profits.
