The Research of Route Programming and Scheduling of the Postal Cars in the Postal Transportation Network

We first establish a step-by-step planning graph theory model in the optimal target of the post-effective in transport network.Next,we solve the model step by step and optimize the answer gradually,using Floyd and Kruskal algorithm.And we get the answer by using Matlab,Lingo,SPSS software,then we give the postal route scheduling program in three different conditions.The step-by-step planning graph theory model has universal applicability in solving the problem of postal route schedule,TSP(Traveling Salesperson),MTSP(Multiple Traveling Salesperson),etc.
