公路零担物流企业末端配送路径优化

The terminal distribution routing optimization of road LTL logistics enterprises

针对公路零担物流企业末端配送货源的不确定性和广泛性、单位运输成本较高等特点,以及存在的配送网络体系不健全、配送路径规划不当等问题,建立相应的配送路径优化数学模型。将JOPT(配送路径优化和移动资源调度算法包)作为优化具体配送路径的手段,进行仿真流程设计、优化参数设定,并进行仿真求解,获得最优的配送路径。结合具体实例,将JOPT算法优化后的配送路径与原路径进行比较,发现配送里程相对缩短,配送成本相应降低。

This paper establishes a mathematical model of corresponding distribution path optimization to solve the problems of the uncertainty and wideness of the goods delivered by the LTL logistics companies,the high cost of the unit transport,the unsound distribution network system and improper distribution route planning.JOPT（Distribution Path Optimization and Mobile Resource Scheduling Algorithm Package）is used as a method to optimize the specific distribution path,design the simulation process,set optimization parameters and perform simulation to get the best distribution path.Combined with examples,the comparison of the distribution path optimized by the JOPT algorithm with the original path shows that the distribution mileage is relatively shortened and the cost is also reduced accordingly.
