Nowadays, tourism is found more attractive as an economic source in countries with cultural and travel destination background. One of the most important factors in attraction of international and domestic tourists is the required tourism facilities. ACCOMMODATION CENTERS are more important destinations through mentioned facilities. Therefore, correct positioning of these CENTERS can make an extension in tourism industry. In this study, Hamedan city was selected as a case study because of several tourist CENTERS and one of the distinguished tourism hubs. Then, GIS was used to analyze the effective factors in positioning of tourist CENTERS, and a layer was defined for each effective factor followed by weight determination for any created layer. Finally, all layers were analyzed and the results were merged using Analytical Hierarchy Process (AHP), and appropriate places for construction of ACCOMMODATION CENTERS were defined. Results were created in different degrees for Hamedan city, which means that regions with degree of 10 from 10 are the ones that have the most priority for constructing ACCOMMODATION CENTERS and vice versa.
