基于供应链网络的建立与道路破坏的定量评估

Based on the Establishment of the Supply Chain Network and Quantitative Evaluation Model of Road Damage

针对49个城市中作为供应点城市的定量分析和道路破坏后最佳路径的评估,以总费用最小和供应点不变为切入点,通过分支定界、比较等方法,分别建立了0-1整数线性规划模型、费用增量优先度模型。运用Matlab、Lingo11软件得出了8个最佳供应城市和使对方总费用增加25%时所破坏的6条道路。

For 49 as outlets in the city urban problems and analysis, and the best path of roads damaged, with the minimum total cost and the supplier does not become a breakthrough point, through the branch and bound, comparative method, respectively, established a 0- 1 integer linear programming model, the incremental cost priority model. Using Matlab, Lingo11 software it is concluded that the eight best supply the city and make each other a 25 % increase in total cost when 6 road.
