鉴于固定费用选址问题的一个重要局限是在运输成本的计算中,假设采用整车运输方式,其运输成本与考虑运输路径时的成本不同会影响选址决策.针对一个钢材销售企业的三级物流网络中的两级设施进行选址,采用多站式运输方式计算运输成本,问题为三级物流网络选址-路径问题.采用嵌入拉格朗日启发式算法的分枝定界方法来求解,并对该方法进行了实验测试,测试结果表明该方法是有效的.
In view of the fixed cost siting problem is an important limitation in the calculation of transport costs, assuming the use of vehicle transport mode, the transport costs and transport costs when considering the differences will affect the site selection decision.For a steel sales enterprise level 3 The two-level facilities in the logistics network are located, and the transportation cost is calculated by multi-stop transportation method.The problem is the location-path problem of the third-level logistics network.The branch-and-bound method of embedding Lagrange heuristic algorithm is used to solve the problem The experimental results show that the method is effective.
