Summary:Selection of suitable places for municipal solid waste landfilling can dispel environmental, social and economic concerns caused by waste expulsion. Regarding the importance of this issue, choosing a comprehensive technique for doing this process makes environmental planners and decision-makers assure the reduction of the deleterious effects of landfilling. The main objective of the present research is to select optimum places for waste sanitary landfill in Shahriar town in Tehran province using Multi- Criteria techniques of FAHP and Hierarchical Fuzzy TOPSIS (HFTOPSIS). First, main factors affecting landfill places were modified using related institutions data and then the data was collected and standardized using Geographical Information Systems. Next, factor weights were calculated using Fuzzy Analytic Hierarchy Process. After applying the weights to the corresponding criteria, using Fuzzy overlay functions, combinations of layers were done. Then, HFTOPSIS method was used to prioritize options. 31 suitable options were calculated through running the above-mentioned methods. Finally, one of these places was selected as the best place. The selected place was located in the south western part of Shahriar. Results showed that the selected sites are located in better places compared to the current one. Thus, this integrated approach showed better performance than that of the other approaches, for it takes into account the inexact nature of the phenomena.
