Research on Logistics Nodes Dynamic Layout Optimization Problem under the Conditions of Green Logistics

根据绿色物流的相关特点,在分析物流节点的内涵基础上,根据物流节点系统结构,构建绿色物流条件下不同时期不同节点系统动态布局最优模型,考虑绿色物流中绿色运输、绿色流通加工等约束,并根据模型特点设计了一个基于最小费用最大流和遗传算法相结合的混合遗传算法来求得最优解。最后通过实例验证了模型与算法的可行性,为物流节点动态布局提供了科学的理论与方法。

According to the relevant characteristics of green logistics, logistics nodes in connotation on the basis of the analysis, according to the logistics node system architecture, the optimal model to build dynamic layout node system at different times un- der different conditions of green logistics, green logistics to consider green transportation, green distribution and processing con- straints and the characteristics of the model based on the design of a hybrid genetic algorithm for maximum flow and minimum cost combination of genetic algorithm to obtain the optimal solution. Finally, an example examples demonstrate the feasibility of the model and algorithm, provides a scientific theory and method for logistics node dynamic layout.
