集散区域快递物流车辆调度模型及其算法

摘要

在分析集散区域快递物流运输特点的基础上，研究了固定时间窗内多车型车辆往返运输的车辆调度问题，建立以运输总成本最小为目标的数学模型，并给出遗传算法求解办法。实例表明，该模型和算法能有效地满足物流车辆调度需求，降低企业的物流成本。%Based on the analysis of the characteristics of the express logistics transportation in distribution ar-ea,the multi-type vehicle scheduling problem is studied with time window. A mathematical model of the vehi-cle scheduling aiming at the minimal transportation cost is established,and a genetic algorithm for solving the model is presented. The examples show that the model and algorithm can solve the logistics vehicle scheduling problem and reduce the cost of logistics enterprises.
