Group Consensus Reaching Methods for Decision Making

Decision making is an essential part of our private and professional life. The consequences of our decisions are sometimes very simple, but very often our decisions affect our life and future significantly. Every decision making problem consists of three major components: the decision makers, the decision alternatives, and the consequences of our decisions. The decision maker can be a single person or a group of people. In real-life most of the practical decision making problems are GDM problems. It is the aim of this book to synthesize consensus reaching methods to solve of the multi-criteria group decision making (MCGDM) problems with the different preference representation formats, including fuzzy preference relations multiplicative preference relations, incomplete fuzzy preference relations, and some uncertain preference relations, etc.
