Abstract
Landfill location selection is a multi-criteria decision problem and has a strategic importance for many regions. The conventional methods for landfill location selection are insufficient in dealing with the vague or imprecise nature of linguistic assessment. To resolve this problem, fuzzy multi-criteria decision-making methods are proposed. The aim of this paper is to use fuzzy TODIM (the acronym for Interactive and Multi-criteria Decision Making in Portuguese) and the fuzzy analytic hierarchy process (AHP) methods for the selection of landfill location. The proposed methods have been applied to a landfill location selection problem in the region of Casablanca, Morocco. After determining the criteria affecting the landfill location decisions, fuzzy TODIM and fuzzy AHP methods are applied to the problem and results are presented. The comparisons of these two methods are also discussed.
Highlights
Landfill location selection of Municipal Solid Waste (MSW) is the determination of a geographic site for a region’s operations concerning waste management
This paper presents a comparative analysis of the methods fuzzy TODIM and fuzzy analytic hierarchy process (AHP) applied to the problem of landfill location selection
The third section, we describe a process of landfill location selection and the main requirements of multi-criteria decision-making methods used in this context
Summary
Landfill location selection of Municipal Solid Waste (MSW) is the determination of a geographic site for a region’s operations concerning waste management. Despite the many researches proposing the use of fuzzy multi criteria decision-making methods, there are no comparative studies of these methods when applied to the problem of landfill location selection. According to the MCDM method and the number of alternatives and criteria, the quantity of preferences required to collect all the data can make the landfill location selection process very long. Different studies in the literature use the fuzzy AHP method (Donevska et al 2011) and other fuzzy multi-criteria decision-making (FMCDM) methods (Beskese et al 2015; Önüt and Soner 2008; Liu et al 2014b) for landfill location selection.
