Convenience stores have become important in urban communities' lives. In addition to selling convenience products in daily life, it also sells simple and diverse special meals. Other than purchasing, collecting and handling public affairs, mail, and parcels are performed on behalf of others. Convenient living services are provided for residential areas and temporary passers-by in the area. Therefore, in urban communities with large populations, establishing business bases has become an inevitable choice for convenience store chains of various brands. There are many brands and fierce competition has become an important decision-making issue for chain convenience stores. Thus, using the Delphi method and fuzzy logic theory, a multi-attribute decision-making model is established based on quantitative analysis. The result provides an effective and objective analysis for the establishment of business bases.
