Applying value analysis and fuzzy logic to select areas for installing waste fills.
This article discusses a methodology for assessing and ranking a predefined universe of objects to assist in the selection of suitable areas for the construction of sanitary landfills. The methodology is, in principle, for universal application. Its development was initially based on the 'Value Analysis' methodology and then on the 'Fuzzy Eigenvector Method', or 'Fuzzy Logic' as it is sometimes referred to. The focus of the study herein is on the comparative appraisal of a group of elements which are part of the guidelines to be adopted when determining the choice of the most suitable site for a sanitary landfill. This set of guidelines includes technical, economical, environmental, social and political aspects. As an example of the methodology proposed, four different areas were chosen. They were studied to determine which is the most appropriate site for the development of a new solid waste fill site. The results for these four areas, together with the functions chosen and function weights, are presented here.
