考虑客户满意度的多配送站低碳物流路径规划

Multi-depot Low-carbon Logistics Vehicle Routing Considering Customer Satisfaction

  • 摘要: 针对电商物流路径规划设计问题,首先,基于综合模态排放模型(CMEM),建立包含多个配送站的碳排放量模型,将碳税成本作为物流配送过程中的一部分.其次,考虑到客户的时间窗限制,构建客户时间窗扰乱罚金函数,根据客户时间窗限制和碳排放量模型,建立考虑客户满意度的多配送站低碳物流路径规划模型.再次,在算法设计阶段,考虑到问题的NP-Hard特性,设计了矩阵编码方式和贪婪启发式初始化策略,设计了多个果蝇种群同时进化的多种群进化机制,并设计了子种群个体之间的交流互动机制.最后,通过实例验证了模型和多种群果蝇优化算法的有效性,并就物流成本、环境保护、客户满意度三者之间的均衡关系进行了探讨.

     

    Abstract: To address the design problems of e-commerce logistics path planning, in this study, we use the comprehensive modal emission model to establish a carbon emission model that includes multiple distribution stations, and take the carbon tax cost as part of the logistics distribution process. Secondly, considering the limited time window of the customer, we construct a customer-time-window-disturbance penalty function, and establish a low-carbon station-distribution logistics path planning model that considers customer satisfaction based on the time window limit and carbon emission mode. Thirdly, in the algorithm design stage, considering the NP-hard characteristics of the problem, we design a matrix coding method, a greedy heuristic initialization strategy, and a multi-species evolution mechanism for the simultaneous evolution of multiple drosophila populations, and design a communication-interaction mechanism between sub-species individuals. Finally, we use examples to verify the effectiveness of the model and the multi-species drosophila optimization algorithm, and discuss the relationship equilibrium between logistics cost, environmental protection, and customer satisfaction.
