A negotiating protocol for group decision support systems

TL;DR

This paper presents a multi-agent based group decision support system utilizing a negotiation protocol with mediation and concession, enabling diverse decision-makers to express preferences through multicriteria analysis methods.

Contribution

It introduces a novel negotiation protocol integrated into a multi-agent system for group decision support, combining mediation, concession, and multicriteria preference expression.

Findings

The system effectively models diverse actors and their interactions.

It supports preference expression via AHP and PROMETHEE II methods.

The protocol facilitates consensus-building among decision-makers.

Abstract

Our contribution concerns interactive decision support systems for group decision support. Through this study, we apply to implement a decisional process aiming to represent the multiplicity of actors, their diversity, their behaviors and their interactions. In this context, we contribute to the design and development of a group decision support system. The system is modeled by a multi agents system while exploiting a negotiation protocol based on mediation and concession. This protocol allows decision-makers to express their preferences using multicriteria analysis methods, mainly the method by total aggregation AHP (Hierarchical Process Analysis) and the method by partial aggregation PROMETHEE II .
