Foundation of Assisted Analysis Model for Site Selection of Supermarket and System Development

Assisting analysis model of supermarket site-selecting is established by combining GIS technology and gray appraisal theory. The model includes the sub-models of location-fitness analysis, candidate-site selecting-optimizing and GIS-assisting analysis. Based on the models or sub-models, assisting decision-making system of supermarket site-selecting has been developed. Eventually, the practice has proved that the assisting decision-making system is totally superior to the traditional ones. The function of powerful data managing and analyzing of GIS lets the policy-makers make decisions according to most abundant data. Visualized manifestation of GIS could make the policy-makers find out where the problems are, and how to raise the decision-making level. The establishment of supermarket assisting decision-making system makes the site-selecting more direct, more scientific, and easier to operate, which can improve decision-making efficiency, and reduce its risk degree.
