Evaluation and Choosing of Recycling Technologies by Using FAHP

Abstract

The evaluation and ranking of recycling technologies for each treated waste with respects to many different criteria has important results for the management team of any recycling center. Improvement of business strategy is based on the obtained rank of recycling technologies. It represents a key success factor for a recycling center in dealing with crisis. Uncertainties in: relative importance of evaluation criteria and priority of recycling technologies under each criterion are described by triangular fuzzy numbers. Relative importance of evaluation criteria is stated by fuzzy pair-wise comparison matrices. Determining of elements values of these matrices can be considered as a fuzzy group decision making problem. Aggregation of individual opinions into group consensus is performed by using fuzzy averaging method and Fuzzy Ordered Weighted Aggregation (FOWA,) Operator Fuzzy Analytic Hierarchy Process (FAHP) is used for determination of rank of recycling technologies with respects to evaluation criteria and its weights. Proposed model is tested by example with real life data.
