green supplier evaluation by using an integrated fuzzy ahp-vikor approach

In recent years, depletion of fossil fuel reserves and environmental challenges such as air and water pollution, global warming, and greenhouse-gas emissions have increased environmental concerns considerably. subsequently, one of the most practical and useful solutions to decrease environmental pollutants is to deploy green purchasing and use of clean energies by organizations or even governments. thus, construction of renewable-energy power plants and, consequently, green supplier selection for equipment of these plants have become increasingly more important. in this respect, this article presents a novel approach to assess and select green suppliers of a solar power plant. the proposed approach integrates fuzzy analytic hierarchy process and vikor methodologies. the results demonstrate the efficiency of the suggested approach as a practical tool to assist managers and ceos of electric power industry in assessing suppliers for their required equipment.
