On account of sustainable municipal solid waste (MSW) management, the determination of appropriate positions for MSW multi-directional landfill sites includes thought of geomorphological, topographical, hydrological, monetary and environmental parameters. Deciding these regions in a manner that limits ecological contamination and well-being dangers is a significant multi-criteria decision-making issue in the controls of land executives. A landfill site choice procedure has been completed utilizing three pure weighting techniques (rank sum, rank reciprocal and rank-order centroid) coordinated with geographical information system instruments. The outcomes demonstrate that 32,045 km 2 (87.4%) of the total area is inadmissible for landfill sites. This study compares the results of three subjective weighting methods at a large-scale regional planning scenario. The exhibited methodology helps chiefs in deciding safe areas for MSW landfill sites. The results show that in the early period of the spatial planning, simplified pure methods can be adequate. In this case, using more complicated methods will not definitely deduce different findings. However, when regional planning requires identifying the spatial scope of the favored specific sites, considering the intersection area proposed by three methods will be ideal.
