Evaluating recovery options by a mathematical model integrated with fuzzy multimoora method

Product recovery option has been one of the strategic decisions for the reverse logistic systems. The decision requires analyzing multi-dimensional and conflicting a variety of factors as well as considering lack of information with regard to time, quantity and quality of the returning products. Because of these reasons, the study is constructed under fuzzy environment. In the study, fuzzy MULTIMOORA method, including three approaches namely Ratio system, Reference point and Multiplicative form methods, is applied by means of generalized interval-valued trapezoidal fuzzy numbers. A hierarchical model with 7 criteria "Product, Economic, Business, Operations, Environment, Market, Legal & Politics" and 20 sub-criteria such as "Technical characteristics, demand, quality, and complexity of processes", are evaluated in the analysis. A real life case study is applied to check the feasibility of the method and a mathematical model is presented.
