Extension of the ARAS Method for Decision-Making Problems with Interval-Valued Triangular Fuzzy Numbers

This paper proposes an extension of the ARAS method which, due to the use of interval- valued fuzzy numbers, can be more appropriate for solving real-world problems. In order to over- come the complexity of real-world decision-making problems, the proposed extension also includes the use of linguistic variables and a group decision making approach. In order to highlight the pro- posed methodology an example of a faculty websites evaluation is considered.
