Problems solved by technology

[0004] Existing vehicle routing problems have the problem that all vehicle cargoes are loaded without considering the associative constraints between cargoes
In general, the time-varying associated logistics vehicle routing problem with hard time windows has multiple constraints, so it is more difficult than the ordinary vehicle problem

Abstract

The invention discloses a method for solving a time-varying associated logistics transportation vehicle routing problem with a hard time window. The method includes the following steps: 1), building a math model of the time-varying associated logistics transportation vehicle routing problem with hard time window constraint; 2), designing an immune ant colony chaos taboo search algorithm to solve the problem. The method has the advantages that actual circumstances in the logistics transportation vehicle routing problem are reflected more accurately, so that a scheduling scheme formulated on the basis of the actual circumstances is more reliable; shortest vehicle traveling distance is taken as an optimization target, so that adapting requirements on the hard time window can be met better. The immune ant colony chaos taboo search algorithm is introduced, so that the method is enabled to have higher global and local optimization capability, and the method is enabled to have higher efficiency in solving large-scale problems.

Description

technical field [0001] The invention belongs to the field of logistics route planning and control, and in particular relates to a method for solving the route problem of time-varying associated logistics transport vehicles with hard time windows. Background technique [0002] Distribution is the core link of the logistics system, and it is an inevitable market behavior born with the market. With the increasingly fierce market competition and the continuous improvement of customer requirements, distribution will play a pivotal role in the future market competition. In the distribution business, the optimal scheduling of distribution vehicles involves a wide range of factors, and there are many factors to be considered. It also has a great impact on the distribution companies to improve service quality, reduce operating costs, and increase economic benefits. [0003] Scholars at home and abroad focus on the study of vehicle routing, mainly because it is the core issue of logis...
