| 摘 要： | 为解决生鲜类物流配送网络选址-路径优化问题,构建了基于服务质量最优化、物流节点建造成本及物流运营服务成本最小化的多目标两层级物流配送网络选址-路径优化问题数学模型,并通过改进遗传算法求解最优方案.对遗传算法中的算子进行优化,解决了传统遗传算法求解过程中无法求得全局最优解以及易陷入局部最优解的现象.通过选取通州区部分区域为背景进行模型验证,得出优化后成本节约了15.71%,说明该模型具有良好的参考价值.

| Abstract: | In order to solve the problem of location-routing optimization for fresh logistics distribution network,this paper put forward a location-routing optimization model of threelevel logistics distribution network for multi-objective of service qulity optimization,logistics node construction cost minimization,logistics operation service cost minimization.And improved genetic algorithm is applied to solve the model.Operators in genetic algorithm are optimized to solve the problem that traditional genetic algorithm is trapped in solution-free and local optimum,which improves the operation efficiency.The cost is 7.67 million,which is 15.71% less than that before optimization. |
