文章针对单一供应商和多零售商组成的非一体化供应链,研究了零售商市场需求依赖于其当前库存水平情形下的库存路径问题(inventory routing problem,IRP);在分散式系统下,建立了供需双方的利润模型,给出了改进的最邻近算法,降低了运输费用,提高了供应链的整体利润,再通过价格策略实现了供应商和各零售商多赢,促进了供应链的协调;并给出算例对模型进行了仿真计算与分析。 This paper studies the inventory routing problem (IRP) under the condition of the retailer’s market demand depends on the current stock level for the non-integrated supply chain consisting of a single supplier and multiple retailers. In a decentralized system, The profit model of both supply and demand sides is given, the improved nearest neighbor algorithm is given, the transportation cost is reduced, the overall profit of the supply chain is increased, and the win-win situation is achieved through the price strategy between suppliers and retailers and the supply chain coordination is promoted The examples are given to simulate and analyze the model.
