Location of Logistics Distribution Centers with Grey Demand based on Hybrid PSO

摘要

In the location of logistics distribution centers there is a lot of grey information, which are helpful to the location of logistics distribution. The principal purpose of this paper is to develop a method for the location of logistics distribution centers with grey demand, and a grey programming model of distribution location with grey sales demand is proposed. Because the grey location model is NP-hard, grey chance-constrained programming and algorithm based on hybrid particle swarm optimization have been proposed to solve it. An example shows that the model and algorithm are effective for dealing with the grey sales demand in location of logistics distribution centers.
