In real life cases, there may be situations when the experts are not sure about the alternatives and may have oscillation between multiple values for an alternative. Hesitant Fuzzy Sets is used to represent the expert’s preferences. The fuzzy clustering for hesitant fuzzy sets is used to identify and manage the non-cooperative experts in the group. The application paradigms include publication paper selection. | ISSN:2249-5789 S Saranya, International Journal of Computer Science & Communication Networks,Vol 6(3),114-120 MANAGING NON COOPERATIVE BEHAVIOR IN LARGE-SCALE GROUP DECISION MAKING 1 , Department of Computer Science and Engineering, PSG College of Technology, Coimbatore, Abstract- Group decision making is one of the most common problems in many organizations. Consensus reaching process is the technique that attempts to reach a mutual agreement among the experts before taking a common decision. Today’s technological advancements demand large number of experts to participate in a group decision making. However, the traditional consensus model is not effective when the group decision making takes place in very large scale as in social networks. To identify the non-cooperative experts who change their preferences collectively against the consensus process Fuzzy clustering is used to group the experts according to their preferences, which are given as numeric values. In real life cases, there may be situations when the experts are not sure about the alternatives and may have oscillation between multiple values for an alternative. Hesitant Fuzzy Sets is used to represent the expert’s preferences. The fuzzy clustering for hesitant fuzzy sets is used to identify and manage the non-cooperative experts in the group. The application paradigms include publication paper selection, International processes like space shuttle related decisions, UN decisions, etc. Keywords— Group decision making, Fuzzy clustering, Fuzzy sets, Hesitant Fuzzy Sets I. INTRODUCTION Group decision making is one of the most common problems in every organization. In the past only the high officials of the organization participate in the decision making process but the situations are not the same due to the technology development. Social networks have enabled professionals from any place to participate in the decision making process without much effort. The .
