Abstract

The invention discloses a parallel computing-based logistics transportation scheduling method, device and equipment and a readable storage medium. For logistics transportation scheduling, the fireworks algorithm is adopted to search the optimal path, on one hand, the fireworks algorithm searching capability is improved through the parallel operation strategy, on the other hand, the fireworks algorithm is optimized through the multi-group cooperative strategy and the novel evolution strategy, local convergence of the algorithm is effectively prevented from occurring too early, and the robustness and stability of the algorithm are improved. The scheme has the characteristics of high operation speed, high convergence capability and high optimization efficiency in the process of realizing logistics transportation scheduling.

Description

technical field [0001] The present application relates to the field of logistics transportation scheduling, in particular to a method, device, equipment and readable storage medium for logistics transportation scheduling based on parallel computing. Background technique [0002] Internationally, the logistics industry is regarded as the basic industry for the development of the national economy, and its development degree is one of the important symbols to measure the degree of national modernization and comprehensive national strength. [0003] The operation of logistics not only determines the overall operating cost of business enterprises, but also directly affects the stability and balance of the operation of the entire business system, so logistics transportation scheduling is one of the core activities of logistics. However, the traditional logistics and transportation scheduling schemes have the problems of low operating speed, weak convergence ability, or low optimiz...
