Considering non-normative extension and too much development of cities, the lack of accurate model of consumption, increasing waste production, the most logical and most economical method for disposal of municipal waste is sanitary landfill. Given that, to identify areas prone to waste landfilling requires application of comprehensive techniques. The main objective for the present research is to select optimum place for waste sanitary landfill using Multi-Criteria techniques of FAHP(fuzzy analytic hierarchy process) and fuzzy TOPSIS(Fuzzy Technique for Order Preference by Similarity to Ideal Solution). First, determinant factors affecting landfill place from various institution were identified, collected and were standardized using geographical information system. Then by using fuzzy analytic hierarchy process, weights are calculated. After applying the weights on the corresponding criteria, using Fuzzy overlay functions combination of layers were done. Then, FTOPSIS method was used to prioritize options. Number of thirty one suitable options were calculated through running above mentioned methods. Then, one options were considered as the best as per prioritization located at south western of Shahriar city. Results showed that suitable elite options are located at better landfill compared to current one. So, this integrated approach, showed better performance than others due to taking inexact nature of phenomena.
