在生产物流系统中,最基本、最重要的功能就是运输功能,运输成本在整个生产物流成本中,占有相当大的比例。因此,研究物流运输车辆的路线优化问题,对降低物流成本具有重要的实际意义。一汽集团可借鉴丰田本地集荷便的车辆调度方法,对各主机公司的零部件入厂物流进行总体规划。集荷便调度是指运输车辆从主机厂出发,按顺序去多个零部件供应商处取货后,再 In the production of logistics system, the most basic and most important function is the transport function, transport costs in the logistics costs of production, occupy a large proportion. Therefore, studying the route optimization of logistics transportation vehicles has important practical significance to reduce the logistics cost. FAW Group can learn from the local Toyota set the load scheduling method of vehicles, the host company’s parts into the factory logistics for overall planning. Set load scheduling refers to the transport vehicles starting from the OEM, in order to go to multiple parts suppliers pick-up, and then
