摘要
首先针对不同类型、数量乘用车的物流运输问题,构建整数线性规划模型,并对模型进行逐层优化求解,通过MATLAB编写通用程序实现计算;在此基础之上,为解决不同目的地的运输要求,采用启发式逐层优化算法进行求解;最后考虑多因素的实际问题,建立分层划分模型,提出构造型分层划分启发式算法求解.计算表明,所建模型计算结果良好,实现了对乘用车物流运输计划问题的优化.
Firstly, this paper work out the different types, the number of Vehicle Logistics Transportation plan built integer linear programming model, and solved by step by step opti- mization algorithm, designed the general program by MATLAB. On this basis, the modal is built by step by step heuristic optimization algorithms to solve the existence of different destinations for transportation requirements. Finally, Considering multiple factors of the actual problem, a hierarchical division model is established by the hierarchical division of heuristic Mgorithm. Calculations show that the model is well, achieving the optimize plan for Vehicle Logistics Transportation.
