| 目的 研究基于供应商管理库存模式下，由一个供应商和多个零售商组成的二级供应链配送系统的库存路径优化问题，确定计划期内各配送周期的长度、数量，对供应链中库存策略与配送方案问题进行协调优化，使系统总成本最低。方法 考虑的成本包括库存持有成本、缺货成本和配送成本。为降低供应链系统的总成本，提出全新的周期可变策略。结果 采用遗传算法求解得出最佳方案。将不同策略的算例结果进行对比分析，结果表明周期可变策略与周期固定策略相比，系统总成本最低节约比例为1.7%，最高节约比例为42.3%。结论 通过对计划期内各配送周期的长度及数量进行划分调整可以有效地节约系统总成本，同时，采用多车型的配送方案明显优于采用同车型的配送方案。 |

| The work aims to study the inventory routing optimization of a two-level supply chain distribution system consisting of a supplier and multiple retailers based on the vendor-managed inventory model, determine the length and quantity of delivery cycle in the planning period, coordinate and optimize daily sales volume to inventory strategies and distribution plans in the supply chain, so as to minimize the total cost of the supply chain system. The costs considered included inventory holding cost, out of stock cost and distribution cost. In order to minimize the total cost of the supply chain system, a new strategy with variable cycle was proposed. The genetic algorithm was used to solve the optimal scheme. The results of different strategies were compared and analyzed. The results showed that, compared with the fixed cycle strategy, in the variable cycle strategy, the lowest saving ratio of the total system cost was 1.7% and the highest saving ratio was 42.3%. The total cost of the system can be effectively saved by dividing and adjusting the length and quantity of each distribution cycle in the planning period. Meanwhile, the distribution scheme with multiple vehicle types is obviously better than that with the same vehicle types. |
