Loading vehicle line optimization method, device and equipment and storage medium

Abstract

The invention relates to the field of logistics transportation, and discloses a stowage vehicle line optimization method, device and equipment and a storage medium, which are used for improving the utilization rate of freight vehicle resources and reducing the freight cost. The method comprises the steps that a stowage vehicle line optimization model based on a tabu search algorithm is set, the stowage vehicle line optimization model comprises decision variables, optimization objectives and a tabu table, the decision variables comprise the number of distribution vehicles and driving paths, andthe optimization objectives enable the sum of the number of the distribution vehicles and the number of empty return vehicles to be minimum under the preset constraint condition; a tabu table is initialized, and an initial solution of a decision variable is generated; iterative operation is performed by taking the initial solution as a current solution of a decision variable; and the number of iterations of iterative operation is counted, when the number of iterations reaches a preset number, a latest update result of the current solution is obtained, and the latest update result is output asa stowage vehicle line optimization result.

Description

technical field [0001] The invention relates to the technical field of logistics transportation, in particular to a loading vehicle line optimization method, device, equipment and storage medium. Background technique [0002] With the continuous development of the logistics industry and e-commerce, the express delivery industry is on the rise, and the express delivery business is increasing year by year. How to control freight costs has become a common concern of logistics companies. [0003] Preventing empty vehicles from returning is an important part of express delivery business cost control. At present, logistics companies generally adopt the method of multi-logistics distribution point cooperation for express delivery, that is, set up corresponding logistics distribution points at different addresses, and the express package starts from the initial distribution point and passes through several transit distribution points. Finally, the courier will be transported to the...

AI Technical Summary

Problems solved by technology

With the explosive growth of express delivery business and the expansion of logistics distribution points, logistics companies have greatly increased the difficulty of planning and managing loading vehicle lines. Due to unreasonable vehicle line planning and other reasons, the phenomenon of empty vehicles returning from time to time occurs, which is undoubtedly It leads to the waste of freight vehicle resources and increases the freight cost
