Abstract

This research focuses on the design and development of an interactive multi-criteria group decision support system (GDSS). This system comprises a set of agents communicating through messages. They aim to find an adequate area that can best address certain criteria among a set of variants (e.g. localization of new infrastructure, shopping mall, hospital, etc.). A GDSS is designed and relies mainly on the presentation of the territory through the functionalities of geographic information system (GIS), and the representation of the multiplicity and diversity of decision makers through the functionalities of a multi-agents system (MAS). Moreover, an argumentation-based negotiation protocol MAS module is provided. This approach is justified by the argumentative nature of the process by which participants justify their choices in order to reach a collective decision. This is achieved by exploiting the multi-criteria methods with an analytic hierarchy process (AHP) and Electre III.
