A GIS - Based Location Selection Method for Prefabricated Component Factory

With the promotion of prefabricated buildings in our country, the number of prefabricated buildings and prefabricated component factories has increased year by year, and some areas have appeared the phenomenon of overcapacity or short supply. In order to avoid the huge losses caused by the above situation, based on the general product demand forecast, combined with literature review and research, this study will use GIS technology to conduct spatial analysis from the market, transportation and cost factors, and obtain the best centralized demand point through buffer analysis and weighted overlay analysis, then predict the demand of the demand point. Based on the determination process of prefabricated component demand point in the main urban area of Xining city, the demand area of prefabricated components is centralized to make the demand area more accurate. The results show that the method has high accuracy and good applicability, which can provide help and reference for the location decision of prefabricated plant in this area.
