Optimally locating new bank branches is a strategic decision in banking industry in order to stay competitive. The importance of this issue is primarily due to the fact that locating branches in appropriate sites is one of the main factors in absorbing and satisfying bank customers. This results in a core benefit for banks, particularly in a vibrant competition. In addition, without a set of well-chosen selection criteria and their prominence, the goal of locating suitable sites for bank branches would not be efficiently achieved. In this research, six most widely used criteria for bank branch location consideration are obtained from the literature review. These criteria include demographic attributes, access to public facilities, transportation, competition, cost and flexibility. In order to prioritize these criteria, an integrated methodology of the intuitionistic fuzzy set theory as well as Decision Making Trial and Evaluation Laboratory Model (DEMATEL) technique (i.e. IFDEMATEL) are utilized. The DEMATEL technique considers interrelationships between criteria. Furthermore, the intuitionistic fuzzy set theory, which has some advantages over fuzzy set theory, to include the vagueness and imprecision of subjective judgments of specialists is applied. As a case study, a well-known Iranian public bank in the city of Rasht, Iran is considered. Consequently, the obtained ranks from the integrated method provide useful information for bank managers in determining efficient locations of their new branches.
