分布式OD运载网络中物流绿色轨迹监测系统的布局优化

Deployment of inspectors for green logistics in distributed OD carrier network

物流系统的能耗和污染等特征的监测是对其进行绿色评价、优化管理以及推进绿色化的基础,为此需要研究绿色物流监测器在运输网络中的布局问题,进一步提出OD运载网络之上的"绿色轨迹监测系统"及其配置优化。在同时考虑监测器覆盖量和线路相关性的基础上,建立一个多目标混合整数规划模型,并设计分布式OD运载网络中OD流最短路径的算法,旨在研究在监测设备有限的约束下提供一种兼具经济成本和环境效益的可行方案。通过仿真实验验证了模型和算法的有效性,并探讨了在此基础上新的研究机会。

Inspection for energy consumption and pollution of logistics system involves green evalua- tion, optimization and management, therefore the deployment of monitors for green logistics in distribu- ted OD carrier network is studied in the paper, and a green-track inspection system and its layout optimi- zation upon the OD carrier network are further proposed. Meanwhile, a mixed integer programming model is established, based on the consideration of monitor coverage quantity and line correlation, and an OD flow shortest path algorithm in distributed OD carrier network is designed. For the limited in- vestment of monitoring equipments, a feasible alternative solution is proposed with promising economic costs and environmental benefits. The model and algorithm are verified through simulation experiments, and some new research opportunities are analyzed.
