The selection of equipment for recycling by using fuzzy COPRAS method

Abstract

The aim of this study is to propose a new fuzzy multi-criteria to evaluate recycling equipment with respect to numerous criteria, simultaneously, taking into account the type of each criteria and its relative importance. The all existing uncertainties into the criteria weights and their values are described by pre-defined linguistic expressions which are modeled by fuzzy sets theory. Fuzzy assessments of the criteria weights are performed in direct way. Determining the criteria weights is based on method for comparison of fuzzy numbers. The rank of possible recycling equipment is obtained by applying modified Fuzzy COPRAS (Complex Proportional Assessment of alternatives) technique. The proposed model is illustrated by example with real-life data come from reverse supply chain existing in the Republic of Serbia. The presented solution provides base for successful improvement of reverse supply chain management.
