This research aims to prioritize the archetypal tourism regions situated on the Oramanat tourism pole in the North West of Kermanshah Province, based on their aptitude for investment. This study is an applied survey type research. Data were gathered through questionnaires and were analyzed using TOPSIS technique. Results indicate that archetypal tourism regions of Shamshir, Ghourighale, Noudeshe, Hajij and Veisolqarn are in the good level; Bouzinmarkhil with SL+i 0.48 is in medium level; the areas of Nowsoudeh, Sarabemamishan, Shervineh, Sarabesefidbarg, Ozgolebamu, Bidmiri and Dalani with SL+i of 0.2 to 0.4 are in the weak level, and Cheshmehrize region with SL+i 0.2 is evaluated to be in the very weak level. Based on the research findings, yielding of the archetypal tourism regions with low level of investment suitability, to investors, is only a mere waste of resources. Therefore, tourism planners are supposed to improve the potentiality of these areas for investment first, and then offer them to investors.
