Information Exchange in Group Decision Making: The Hidden Profile Problem Reconsidered
Group decision making provides a mechanism for channeling individual members’ knowledge into productive organizational outcomes.

We report a hidden profile experiment where we indu...

Decision processes for solving group decision making problems are composed of two phases: (i) aggregation and, (ii) exploitation. When experts that participate in the group decision making process are not able to express their opinions using a same expression domain, then the use of information assessed in different domains, i.e., heterogeneous information, is necessary. In these cases, the inf...
متن کاملINFORMATION MEASURES BASED TOPSIS METHOD FOR MULTICRITERIA DECISION MAKING PROBLEM IN INTUITIONISTIC FUZZY ENVIRONMENT
In the fuzzy set theory, information measures play a paramount role in several areas such as decision making, pattern recognition etc. In this paper, similarity measure based on cosine function and entropy measures based on logarithmic function for IFSs are proposed. Comparisons of proposed similarity and entropy measures with the existing ones are listed. Numerical results limpidly betoken th...
