Interactive Aggregation/Disaggregation Dichotomic Sorting Procedure for Group Decision Analysis Based on the Threshold Model

In this paper, a new multi-criteria decision-making procedure is presented, which captures preferential information in the form of the threshold model. It is based on the ELECTRE-like sorting analysis restricted by the localization principle, which enables high adaptability of the decision model and reduces the cognitive load imposed on the decision-makers. It lays the foundation for the introduction of three concepts that have been previously insufficiently supported by outranking methods – semiautomatic derivation of criteria weights according to the selective effects of discordance and veto thresholds, convergent group consensus seeking, and autonomous multiagent negotiation. The interdependent principles are justified, and the methodological solutions underlying their implementation are provided.
