FACILITIES LOCATION MODEL TO MAXIMIZE THE SUM OF REALIZED DEMAND

摘要

In this paper, facilities location model based on Spatial Interaction Models (SIM) is concerned. Initially outlines of SIM and location problem based on SIM are described. Secondly, a new model of SIM which is developed from Non-constraint type of SIM is proposed. In this model a new concept Maximum Realized Demand is applied. Next a location problem to maximize the sum of realized demand is proposed which is based on developed SIM.A method of solution based on Stochastic Descent Method and Stochastic Approximation Method is presented, and the effectiveness of presented method is confirmed through numerical analyses. Finally, 3 simulations of optimal location analyses are shown, and characteristics of presented location model are examined.
