Problems solved by technology

It mainly has the following deficiencies: (1), the singularity of the algorithm research for solving the optimization problem of the logistics distribution route, which makes the solution of the problem also specific and singular; (2), in the algorithm for solving the optimization problem of the logistics distribution route, some The effect is good, but the computational complexity is high; some computational complexity is low, but the effect is not ideal; (3), when many algorithms solve the logistics route optimization problem, they are often prone to problems such as "stuck in local optimum"

Abstract

The invention relates to a route optimizing method for a logistic distribution vehicle. The method comprises the following steps: one, parameter setting and initializing; two, if Nc is less than or equal to Nmax, judging whether the iteration number reaches the maximum iteration number or not, if so, ending circulation and performing step seven; and otherwise, performing step three; three, merging and regulating a logistic distribution route; four, restructuring, inserting and regulating; five, evaluating the cost; six, selecting an optimal logistic distribution route scheme; and seven, obtaining the optimal route scheme for the logistic distribution vehicle. The method for optimizing the logistic distribution route improves the convergence property of the logistic distribution route optimization and can efficiently obtain the optimal logistic distribution route scheme through an abstract enterprise merging action and a merging method consisting of merging operation, restructuring operation and the like.

Description

(1) Technical field [0001] The invention relates to a route optimization method for logistics distribution vehicles, in particular to a method based on this patent [0002] The method is a time window constrained logistics distribution and vehicle routing optimization method. (2) Background technology [0003] The logistics distribution route optimization problem, that is, the vehicle routing problem (Vehicle Routing Problem, VRP), was proposed by Dantzig and Ramser in 1959. Specifically, according to the known conditions and target constraints of logistics distribution, find the most suitable distribution route to minimize the cost of logistics distribution. With the development and prosperity of the market economy, the proportion of logistics distribution in the cost of goods transportation is also increasing. Therefore, how to reduce the cost of logistics transportation and improve the efficiency of logistics transportation has become increasingly important and has beco...
