DEMAND STRUCTURE OF REGIONAL FACILITIES FROM THE VIEWPOINT OF SELECTION PROCESS BY USERS : Analysis of demand decline by distance using computer simulation

Abstract

This article investigates the demand structure of regional facilities from the viewpoint of selection process by users. To this end, demand decline by distance is analyzed by computer simulation of two cases. In the first case the users select the nearest facilities with vacancy. In the second case they select the nearest vacant facilities with the satisfaction level which meets a baseline formed through the selection process. The result shows that the decline curve by distance consists of high demand area in the proximity of facilities, flat demand area within the Voronoi region and exponential decline area outside.
