【摘要】：生鲜农产品是人类日常生活中不可或缺的消费品,其本身独有的鲜活性、易腐性、不易保鲜、流通损耗大、产出随机波动大、运输困难等特点,一直是困扰农产品产销体系的重要因素。生鲜农产品供应链也由于供应分散、分销损耗、缺乏协同等,一直以来存在投入大、运营效率低等问题。论文基于生鲜农产品分销过程中的变质损耗特性,分别在供应商实施保鲜努力投资和分销商实施促销努力两种情况下,讨论生鲜农产品的最优订购策略,并在不同的合作契约下分析供应链的协作与优化。论文首先假设市场需求受产品价格和新鲜度的双重影响,通过构建一个随时间呈指数形式衰减的新鲜度函数,以变质品库存模型为基础建立分销商库存模型,在考虑生鲜农产品变质损耗的基础上探讨分销商的最优订购策略。其次,论文从供应链系统的角度出发,考虑产品在流通过程中数量和质量的双重损耗,分别在集中决策和分散决策下讨论分销商的最优保鲜努力水平,并通过一个收益共享契约的引入来实现供应链的协调。进一步,论文将需求函数进行拓展,假设产品需求受市场价格、产品新鲜度、促销努力以及库存水平等多方面影响,并考虑分销商的产品促销努力,讨论分销商的最优促销努力水平和产品订购策略,最后分析并验证了供应商采用合适的数量转移支付契约能够实现供应链的协调。
[Abstract]:Fresh agricultural products are indispensable consumer goods in human daily life. They are unique to fresh activity, perishable, not easy to keep fresh, large circulation loss, large random fluctuation of output, difficult transportation and so on. It has been an important factor puzzling the production and marketing system of agricultural products. The supply chain of fresh agricultural products also has the problems of large investment and low operational efficiency due to the scattered supply, loss of distribution, lack of coordination and so on. Based on the characteristics of deterioration and loss in the distribution of fresh agricultural products, this paper discusses the optimal ordering strategy of fresh agricultural products under the conditions of supplier's investment in fresh-keeping efforts and distributors' promotion efforts. And analyze the cooperation and optimization of supply chain under different cooperation contracts. This paper first assumes that market demand is affected by product price and freshness. By constructing a freshness function with exponential decay over time, a distributor inventory model is established on the basis of deteriorating inventory model. On the basis of considering the deterioration loss of fresh agricultural products, the optimal ordering strategy of distributors is discussed. Secondly, from the point of view of supply chain system, considering the double loss of quantity and quality in the process of product circulation, the paper discusses the optimal level of fresh-keeping efforts of distributors under centralized and decentralized decisions, respectively. And through the introduction of a revenue sharing contract to achieve supply chain coordination. Furthermore, the paper expands the demand function, assuming that product demand is affected by market price, product freshness, promotion effort and inventory level, and considering the distributor's product promotion efforts. This paper discusses the optimal promotion efforts and product ordering strategies of distributors, and finally analyzes and verifies that the supplier can coordinate the supply chain by adopting the appropriate quantity transfer payment contract.
