Postal distribution network ensures the operation of the postal corporation,while both postal route planning and vehicle scheduling are important factors related to network *** the actual postal operations,this article studies the postal system's vehicle routing problem and builds a nonlinear programming model with time windows and capacity constraints in order to design the postal regional logistic distribution *** planning follows the step by step decision-making *** first step is to establish the region minimum costs model and the second step is to establish the county level minimum costs *** order to solve the postal route planning and vehicle scheduling problems with time and load capacity constraints,we combine the traditional optimization methods and the minimum spanning tree,tspalgorithm,Floyd algorithm and advanced greedy algorithm,and then build an improved *** the use of MATLAB,we get the optimal *** results also show that the algorithm can obtain higher quality solutions,and has theoretical value and practical significance.
