【摘要】：在对资源共享模式下的整车物流路径优化问题进行分析的基础之上,提出了共享车辆和共享车辆分拨中心两种资源共享模式下的整车物流路径优化网络,构建了以整车运输总成本最小为目标的数学优化模型,并设计了基于遗传算法的启发式算法用于求解该问题。结合华晨宝马、上海通用及广州本田的整车物流运输实例求解,认为文中所提出的资源共享模式可以节约总成本30%,能有效降低运营成本。对不同公路重载单位运输成本下最优成本的变化情况进行了比较分析。结果表明:单位运输成本越大,采用传统单独运输的成本越大,越应采用共享运输模式;但若公路重载运输单位成本与铁路和水路运输的成本越接近,则共享模式的优势越弱,成本节省率也就越低。
[Abstract]:Based on the analysis of vehicle logistics path optimization in resource-sharing mode, the vehicle logistics path optimization network based on shared vehicle and shared vehicle distribution center is proposed. A mathematical optimization model aiming at the minimum total cost of vehicle transportation is constructed, and a heuristic algorithm based on genetic algorithm is designed to solve the problem. It is considered that the resource sharing mode proposed in this paper can save 30% of the total cost and reduce the operating cost effectively. The variation of the optimal cost under the unit transportation cost of different highways is compared and analyzed. The results show that the higher the unit transportation cost is, the more the unit transportation cost is. The higher the cost of traditional transportation alone, the more sharing transport mode should be adopted, but if the unit cost of highway heavy haul transportation is close to the cost of railway and waterway transportation, the advantage of sharing mode is weaker and the cost saving rate is lower.
