Abstract

The purpose of this study is optimal location for waste disposal in Ilam city. A questionnaire and a survey of experts was used to conduct the research. For this purpose, three main criteria were considered: environmental, hydrology, access roads and population centers. For each main criterion, sub-criteria were considered. The data were then weighted based on the network analysis (ANP) process and used ArcGIS10.2 software to integrate the information layers. Based on the criteria and sub-criteria studied, 4 areas for waste disposal were suggested. By determining the weight and ranking of the criteria and the coefficient of each of the criteria and the formation of paired comparison matrix tables, the most appropriate option was selected among them for landfilling. The results show that area one with a weight of 0.419 and an incompatibility rate of 0.05 is more appropriate than the four selected options according to the criteria and sub-criteria studied such as main communication routes, vegetation and animal status, hydrological status and even geology.
