The use of Renewable Energy Resources (RER) is growing rapidly for energy generation and several studies indicate that these will have a huge contribution in the future. Selecting RER is a complex problem involving different criteria and alternatives. The first aim of the study is the development of an evaluation model to select the most appropriate RER in Turkey. Evaluation of RER alternatives can be seen as a multi criteria decision making (MCDM) problem that can be solved with flexible tools to handle complex situations and assist decision makers (DMs) in mapping out the situation. In this process, Group Decision Making (GDM) involves multiple DMs who have different goals or ways of thinking and can assess the decision process distinctively different from others. Linguistic interval fuzzy preferences with DEMATEL, ANP, TOPSIS integrated techniques are utilized to eliminate uncertainty and to better represent DMs' preferences. The originality of the paper comes from its ability to propose effective and comprehensive evaluation model for both Turkey and literature and apply to a real industrial problem to improve the RER selection process. Another contribution is to adapt integrated techniques including linguistic interval fuzzy preferences with DEMATEL, ANP, TOPSIS for the first time. (C) 2017 Elsevier Ltd. All rights reserved.
