Use of GIS in Applying Fuzzy, Boolean and AHP Algorithms in Landfill Location (Municipal Landfill Location Study)

Sustainable development (SD) can be defined as the right and correct usage of various resources to promote the quality of life. Using productive resources and recycling them properly plays an important and effective role in health and growth of a society. Waste, which because of its large amount and being returnable to the nature considered as a productive resource, is one of the most environmental problems. The present study tries to examine different factors effecting on landfill sites and the value of each while introduces usage of new algorithms to site selection and decision making practices. Optimal areas for burying municipal wastes were selected by Boolean, fuzzy and analytic hierarchy process (AHP) methods using the GIS techniques. Effective factors in landfill were generally classified into 4 main and 15 secondary criteria. Site selection in the area carried out by different algorithms, then final results were extracted and AHP method selected with respect to field inspections, volume evaluation of place, and value of local land rather than Boolean and fuzzy ones. Site selection on the one hand and careful management of landfill operation on the other hand reduce the pollution caused by this natural cycle to the lowest possible level. Thus, minimizing waste disposal and maximizing material recycling must take priority over all other municipal waste management plans
