Abstract
       In this research a Decision Support System (DSS) has been used to support decision makers for policy making regarding the landslides which typically take place around villages. Definite software was utilized to design a model which include three strategies: landslide stabilization, village relocation, and risk acceptance. The model introduces the optimal strategy considering four effects (i.e., cost, reduction of fatalities, peoples and local manger point of views). To determine the cost of stabilization, in the first step the stabilization method should be selected. This is also is performed using the other DSS system. In the next step, the cost of stabilization is computed. The cost for the other alternatives is also assessed. The other effects are evaluated for the other alternatives. The user can select the optimal method for a certain landslide after completing the designed questionnaires regarding engineering geological characteristics, reduction of fatalities, people and local manger point of views. The Barikan landslide in Taleghan region was studied using the model. The stabilization method was selected as the most appropriate strategy for the landslide. The selected alternative is in a good agreement with those presented as the results of site investigation.
