Theory and Approaches of Unascertained Group Decision-Making

The question of how to aggregate structural uncertainties of multiple variables to determine the group preference, on the basis of the complexity of group decision-making, is a problem that urgently waits for a resolution. This book expresses the complexity existing in each group decision-making process by employing complex networks and studying various methods of aggregating preference information from various unascertained, time-series based decision-making groups structures. It covers the decision-making mechanism of unascertained preference information, aggregation of unascertained preference information, and various methods of aggregating preference information in dynamic environments.
