Selection of logistics distribution center location for SDN enterprises

Abstract

The location selection of the logistics distribution center for a supply and demand network (SDN) enterprises directly affected the efficiency of the logistics system operation and the customer service level. In this paper, we present a location selection model of the logistics distribution center for SDN enterprises. In order to improve the optimization effectiveness of the traditional methods in solving the location selection problem, an improved firefly algorithm was presented. By introducing a coordination factor, the search step can be automatically adjusted, and the accuracy of the algorithm can be improved. By introducing a chaotic search strategy, the diversity of firefly populations and the global optimization ability of the algorithm can be improved. The simulation experiments showed that the improved firefly algorithm achieved a more favorable effectiveness than three other algorithms we tested.
