This book is intended for researchers and postgraduates who are interested in the consensus reaching process in group decision-making problems. It puts forward new optimization-based decision support approaches to help decision-makers find roadmaps to consensus with minimum adjustments. Simulation experiments and comparison analysis are subsequently conducted to assess the validity of the proposal. After reading this book, readers will possess a number of valuable tools for building consensus with minimum adjustments in the context of group decision-making. Further, the proposed approach can effectively reduce costs in consensus building.​

The first book of its kind to use optimization-based approaches to support consensus building Can achieve consensus with minimum adjustments and substantial cost savings by applying the proposed approaches Simulation experiments and comparison analysis are included to justify the proposal?
