Abstract

Provided is a logistics distribution path planning method based on regional multi-strategy. The method includes: firstly, encoding an optimization problem of a vehicle distribution path according to adistribution place and a vehicle, and converting the optimization problem to a variable with an algorithm capable of being optimized; then designing a differential evolutionary algorithm based on theregional multi-strategy for a distribution path optimization model, classifying similar individuals as one category through partitioning, selecting the individuals from different categories in a variation process to guide variation, generating test individuals of each individual by employing two different variation strategies, and selecting the superior test individual for update to improve the algorithm searching efficiency, increase the population diversity and avoid premature convergence; and finally decoding an optimal solution obtained through optimization according to an encoding rule to obtain an optimal distribution path scheme. According to the logistics distribution path planning method based on regional multi-strategy, the searching speed is fast, and results are reliable.

Description

technical field [0001] The invention relates to the field of logistics distribution, e-commerce, intelligent optimization and computer application, and in particular to a logistics distribution path planning method based on regional multi-strategy. Background technique [0002] With the rise of many new industries, modern logistics has become a new research hotspot in the field of academic research. The scientific development of the logistics industry helps to promote the rapid, healthy and scientific development of the regional economy and promote the adjustment of the industrial structure. Therefore, domestic cities focus on the construction of logistics distribution centers, and the corresponding infrastructure for logistics in each city is rationally allocated. Logistics distribution The scope and speed of logistics and distribution are unprecedented. In the logistics distribution system, the cost of the distribution route problem accounts for a large proportion of the ...
