Abstract
Two-echelon logistics distribution routing problem is an important optimization problem of the logistics distribution networks. It is composed of distribution center location problem and distribution routing problem. Distribution center location problem aims to find the best locations of distribution centers from all the distribution points. Meanwhile, the distribution center needs to be assigned to serve the distribution points. The goal of distribution routing problem is to decrease the total cost of delivery. In this paper, an improved version, colliding bodies optimization with cue ball (CBCBO), is proposed to tackle two-echelon logistics distribution routing problem. The new algorithm improves the lack of the colliding bodies optimization (CBO) algorithm which the number of populations must be even. The new approach based cue ball enhanced exploration ability. A strategy, elite opposition strategy, is used to promote exploitation ability. In the last, the effectiveness of the new algorithm is tested by simulation experiment. The proposed approach demonstrates its capability to optimize two-echelon logistics distribution routing problem.
