This paper formulates the selection of high-technology project alternatives as a multicriteria group decision making problem, and presents a group decision making method for effectively solving the high-technology project selection problem under hesitant fuzzy environment. Hesitant fuzzy set is used to deal with the conditions where the decision makers hesitate among several values in evaluating the...
Intuitionistic Fuzzy TOPSIS (IFT) is an effective decision making technique for fuzziness nature of linguistic assessments. This paper proposes a novel methodology for Multiple Attribute Group Decision Making (MAGDM) problems in intuitionistic fuzzy environment. The proposed methodology is based on utilizing the hesitancy degree to determine decision makers' weights distinctively and, a non-linear...
The decision making is the most important activity for every organization. Group decision making (GDM) is the main method in the decision making process.

This paper presents a new decision making tool when the decision data are not crisp data and the decision maker(s) want(s) to rank the alternatives during an interactive process. In this paper, we propose an interactive method which uses qualitative data to calculate weights of criteria and rank the selected alternatives. Because of existence of linguistic terms in the decision matrix and the weight...
