Extension of Fuzzy ELECTRE based on VIKOR method

• An extended ELECTREI method based on VIKOR is introduced.
• consider ELECTREI partial ranking problem and try to mitigate this problem with regard to relations between VIKOR and ELECTRE.
• The proposed method considers the fuzziness in the decision data and group decision making process.

Many decision problems in real-world deal with conflicting criteria, uncertainty and imprecise information. Some also allow a group of decision makers (DMs) to make their opinions independently. Multi-criteria decision making (MCDM) is a well known decision method that can make the quality of group multiple criteria decisions better by creating a more explicit, rational and efficient process. A group of MCDM models known as “outranking methods” have been used to rank a set of alternatives. ELECTRE I is an outranking method which is simple, but provides partial ranking. So we consider VIKOR and try to mitigate this problem with regard to relations between VIKOR and ELECTRE. The objective of this paper is to extend ELECTRE I method based on VIKOR to rank a set of alternatives versus a set of criteria to show the decision maker’s preferences.
