Problems solved by technology

[0003] The logistics distribution vehicle route planning problem is an NP-hard problem. The initial heuristic method to solve the VRP problem takes a long time to solve the problem. The wiring staff waits a lot of time for the wiring results to return, which makes it difficult for the intelligent wiring to be implemented, and the solution method is serialized. , resulting in the solution of a single solution cannot be iteratively optimized
At the same time, the solution found also has unscientific business operation dimensions and unavailable lines

Abstract

The invention discloses an intelligent route arrangement method for logistics distribution vehicles. The method is characterized by comprising the following steps of: 1, carrying out vehicle construction according to an input order, and generating a distance-time matrix according to road network and road condition data so as to set a cost matrix; 2, establishing a target function through simulating a heuristic strategy of annealing and set soft and hard constraints; and 3, carrying out repeated iteration to find an optimum route of an order set. According to the intelligent route arrangement method for logistics distribution vehicles, the solution efficiency is improved, the problem solution time is shortened in multiples, the transportation routes are optimized, better global optimum solutions are obtained, and the logistics costs of companies or customers are reduced.

Description

technical field [0001] The invention belongs to the application field of computer technology, and in particular relates to an intelligent wiring method for logistics distribution vehicles. Background technique [0002] VRP problem (Vehicle Routing Problem, VRP) solution algorithm is divided into precise algorithm, traditional heuristic algorithm and intelligent optimization algorithm. The exact algorithm can find the global optimal solution of the problem, but the amount of computation increases exponentially with the scale of the problem, so it is not suitable for solving VRP problems of a certain scale. The traditional heuristic is an innovation based on the precise algorithm, but it is still subject to certain limitations. The intelligent optimization algorithm is a better solution, more suitable for solving large-scale VRP problems, and when the simulated annealing algorithm solves the path problem, it not only accepts the state that improves the objective function, but...
