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.

In the present study, the authors propose a group decision support system (Web-GDSS), which allows multi-agents systems and multicriteria analysis systems to help decision-makers in order to obtain a collective decision, using web services. The proposed system operates on two main stages. First, decision-makers are in a different location away from each other. They must store their location in databases and invoke the appropriate web service. Second, in the case of negotiation between decision-makers, monotonic concession protocol will lead to an agreement using CONDORCET and BORDA voting methods.

Communication Platform

In a group decision support system, the various decision-makers have their own information, constrains, decision strategies, preferences, and objectives which are generally not shared or communicated. This implies that the group decision process is distributed between the different entities implicated and impacted by various group members' characteristics. Solution to this problem is to find a decision that would be acceptable to all the decision-makers, following the necessity of a negotiation process that allows the elaboration of a common agreement for a group that faces a conflict on the decision to take. In the current study, the authors propose to establish a communication platform for a group decision support system (GDSS) based on web services, incorporating a multicriteria analysis methods and a negotiation protocol.

Hierarchy Process

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.

Simple Additive Weighting

The Group Decision Support System is a tool used to help group decision makers become faster and more objective. A case study at Serang Raya University is the selection of employees for promotion. The problem is the difficulty in determining which employees will be promoted to fill a certain position and spend a lot of time and how to do the calculation? The research methodology used is system analysis, and calculation of the Simple Additive Weighting (SAW) method. The criteria chosen are based on staffing policies. The decision makers involved were the dean of the faculty, the head of the staffing department and the university's rector. Simple Additive Weighting (SAW) can determine the weight value for each attribute, then proceed with the ranking process that will select the best alternative from a number of alternatives. The results are used to make it easier for users to choose the employees to choose for promotion. This system is expected to help speed up employee decision making to be promoted.
