青岛保税港区物流企业货运路线优化研究

Research on Freight Transport Route Optimization of Logistics Enterprises in Qingdao Bonded Port Area

基于现有的研究理论及其研究成果,结合青岛保税港区A公司的运输现状,针对A公司货运路线具有一个配送中心、多个配送点、时间窗限制、开环的VRP等货运特点,在同时满足运输路径、运输时间、运输载重、车辆需求等约束条件下,以总运输成本最低为目标,构建了青岛市保税港区A公司货运路线VRP模型,采用节约里程法进行货运线路优化,优化后的线路可以提高货运效率、服务满意率并降低货运成本,为青岛保税港区A公司货运决策提供了科学参考。

In this paper, based on existing theories and research findings, combined with the transportation status of a company A in the Qingdao Bonded Port Area, in light of the characteristics of the freight transport route of the company such as single distribution center,multiple distribution points, time window restrictions and open-loop VRP, etc., and aiming to minimize the total transportation cost while simultaneously meeting the constraints of transportation route, transportation time, transportation load, and vehicle demand, we built the VRP model of the freight transportation routes of the company, and used the mileage-saving method to optimize them which could improve the freight efficiency and service satisfaction, and reduce the freight cost of the company.
