Ranking of recycling technologies metal components of end of life vehicles by using modified electre

The evaluation and selection of recycling technologies presents one of the most important operational manage- ment problems. In this paper, a new fuzzy model to evaluate recycling technologies with respect to numerous criteria, simultaneously, taking into account the type of each criteria and its relative importance. The relative im- portance of criteria and their values are modelled by interval triangular fuzzy numbers type-2. Determining the criteria weights is stated as a fuzzy group decision making problem. The ranking of considered recycling technolo- gies is obtained by applying modisied ELECTRE. A case study with real-life data which come from reverse supply chain existing in the Republic Serbia is presented to illustrate the proposed method. The presented solution en- ables the ranking of recycling technologies and provides base for successful improvement of reverse supply chain management.
