Abstract
Selecting landfill site is an important component of waste management process. Inappropriate selection of a site can engender environmental damage, economic inefficiency, and social and political conflict. These concerns indicate that environmental, economic, and social factors should be considered simultaneously when selecting the landfill sites. The site selection of landfill is a complex and multicriteria decision making process, which requires evaluation of several factors where many different attributes are taken into account. The purpose of this study is to examine a decision making process for site selection. First, we identified potential sites through preliminary screening based on exclusionary criteria. Secondly, data layers were created by collecting data and estimating spatial distribution for environmental, economic and social factors. Finally, after evaluating them based on siting criteria, the data layers were combined by fuzzy gamma operator to select candidate sites. Fuzzy analytic hierarchy process (FAHP) was also used to make pairwise comparisons and assign weights to decision criteria.
