Fuzzy Multiattribute Decision-Making for Solid Waste Management with Technological Complications

Fuzzy set theory has been widely used to account for uncertainty in decision-making. This chapter provides an extended insight into the fundamentals of fuzzy set theory and existing fuzzy multiattribute decision-making problems. A case study in Portugal was carried out to explore possible applications of interval-valued fuzziness (IVF) in dealing with screening recycling alternatives in Setúbal region area. In this exercise, the essence of IVF was emphasized in solid waste management (SWM) decision-making. Recent challenges for SWM in Europe are intimately tied to the fulfillment of the prescribed recycling and organic waste recovery targets required by European Directives. The selection of waste management strategies to improve sustainability in the Amarsul system is a challenging issue particularly when trying to reach the targets at the national level as set by European Directives.
