研究了非一体化供应链环境下的库存路径问题,给出改进的最邻近算法。针对由单一供应商和多零售商组成的两层供应链系统,通过降低运输费用,提高供应链的整体利润;通过价格策略,重新分配供应链利润,实现供应商和各零售商多赢,从而促进供应链协调。给出算例及其计算结果,并通过实验对算法的性能进行了分析,实验结果表明该算法对于促进供应链协调是有效的。
The inventory routing problem in non-integrated supply chain is studied, and the improved nearest neighbor algorithm is given. For a two-tier supply chain system consisting of a single supplier and multiple retailers, the overall profit of the supply chain can be increased by reducing transportation costs; the supply chain profit can be redistributed through the price strategy to achieve win-win for suppliers and retailers Promote supply chain coordination. An example is given and its calculation results are given. The performance of the algorithm is analyzed through experiments. The experimental results show that the algorithm is effective to promote supply chain coordination.
