Abstract

Sustainable suitability analysis for landfill sites is an important and necessary issue for authorities of solid waste planning in the fast growing zones, due to the increasing complexity coming from dealing with various disciplines and requirement and the needy of satisfaction. A combination of geographic information systems including spatial analysis, and artificial neural network ANNs were employed in this study for decision-makers in the sustainable suitability analysis problems in Malaysia and GIS was used to manipulate and present spatial data. The GIS analysis reveals three distinct groupings based on actual conditions of the case study area, environmental factors, economic factors and social factors which are reflection of different factors contributing to the sustainable development. The result shown that ANNs has good information extraction and evaluation functions of the suitability value based on the exact relationship between the input criteria and the output landfill site data with high coefficient of determination (R2) which help decision-makers to analysis sustainable suitability for landfill sites.
