Abstract: Location-allocation is a important research area in transportation problem,and P-Hub median is widely used in aviation,communication,post system and so on.Many heuristic methods are applied to find optimal solution in P-Hub median problem,such as GA,SA,Hopfield Network etc.With the number of customers and service centers known,this article presents the solution method based on artificial neural network SOFM,which uses self-learning of neurons to get optimal location and cluster.

Key words: location-allocation problem, P-Hub median problem, SOFM
