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.

We propose a utility revision mechanism for persuasion among agents in the Group Choice Design Support System (GCDSS). GCDSS is a group decision support system based on multiagent negotiation. In GCDSS, each user manages a system for an Analytic Hierarchy Process (AHP) and an agent. Each user subjectively constructs a decision hierarchy and determines weights of alternatives using AHP Based on the hierarchy and weights, agents negotiate with each other on behalf of users. In negotiation, agents attempt to persuade each other. If an agent is persuaded, the agent attempts to revise its utility for a state of its decision hierarchy by adjusting pairwise comparisons in AHP We propose a utility revision mechanism for persuasion among agents using the user’s subjective decision hierarchy of AHP to make persuasion more flexible. Agents try to make their decision hierarchy reliable to revise its utility.

Tujuan dari penulisan makalah ini adalah mengembangkan suatu Group Decision Support System (GDSS) untuk menentukan penilaian kinerja dan peringkat Guru. Metode yang digunakan dalam penulisan ini adalah metode Analytical Hierarchy Process (AHP) dan Borda. Metode AHP digunakan untuk menentukan penilaian kinerja setiap guru. Sedangkan metode Borda digunakan untuk menentukan peringkat guru. Hasil yang diperoleh adalah sebuah GDSS yang dijalankan menggunakan LAN dan dapat diakses oleh multi-user yaitu Kepala Sekolah, sesama Guru dan Murid. Hasil evaluasi menunjukkan 67% user sangat setuju dan 33% user mengatakan setuju bahwa aplikasi membantu dalam proses penilaian guru, hasil evaluasi lainnya menunjukkan 58% user sangat setuju dan 42% user setuju bahwa aplikasi mudah untuk digunakan.
