TL;DR: A fuzzy multicriteria decision-making methodology is suggested for the selection among energy policies, based on the analytic hierarchy process (AHP) under fuzziness, which determines the best energy policy for Turkey.
Abstract: Since the correct energy policy affects economic development and environment, the most appropriate energy policy selection is excessively important. Recently some studies have concentrated on selecting the best energy policy and determining the best energy alternatives. In most of these studies, multicriteria and fuzzy approaches to energy policy making are frequently used. The fuzzy set theory is a powerful tool to treat the uncertainty in case of incomplete or vague information. In this paper, a fuzzy multicriteria decision-making methodology is suggested for the selection among energy policies. The methodology is based on the analytic hierarchy process (AHP) under fuzziness. It allows the evaluation scores from experts to be linguistic expressions, crisp or fuzzy numbers. In the application of the proposed methodology, the best energy policy is determined for Turkey.

TL;DR: In this article, the authors introduce concepts of entropy of interval valued fuzzy set which is different from the entropy on intuitionistic fuzzy sets and on interval-valued fuzzy sets, and discuss their relationship between similarity measure and entropy of intervals valued fuzzy sets in detail.

TL;DR: The outranking methods as a special subgroup of MCDM methods are particularly suitable for integral decision making through the notion of weak preference and incomparability, which better represent the real decision situation, as demonstrated in this paper.
