Study On Enterprise Group Decision Support Systems Based On Multi-Agent Systems

With the rapid development of information technology and communication technology, and the appearance of dynamic alliance, the distributed group decision in different location/different time have been becoming a new trend. The distributed group decision actually is a process of group interaction and cooperation, not general cooperation, but rapid, agile and exact coordination that require some new technologies and new methods to support decision members' action, coordination pattern and decision process.Agent has become an important technology in both artificial intelligence and mainstream computer science. Agent and Multi-agent systems (MAS) technology is a rapidly development area and research. Agent and MAS are being used in broad fields: complex industry control systems, electricity system management, enterprise information integration and new enterprise organization. This work is support by Chongqing Research Award of Applications Foundation: Agent-based Initiative Information Discovery and Service (No: 6802). This dissertation is devoted to the theoretical and practical study of enterprise group decision support systems (GDSS) based on MAS. The main contents are as follows:1. The historical development of GDSS is reviewed from theory and practice. Great emphasis is place on the lacks of GDSS, and similarities and differences between DSS and GDSS. 2. The methodologies of artificial intelligence and their functions in GDSS are studied, and the historical development of GDSS is reviewed from theory and practice as well. Then the thought of using object-oriented technology and MAS to construct GDSS is proposed. Great emphasis is place on research methods of GDSS based MAS.3. The integrated framework of flexible GDSS based distributed objects is proposed. Then this dissertation puts forward the thought of establishing enterprise management GDSS that takes departments as basic decision units by the study on the internal structure, communication, function, process algorithm, implementation pattern of various agent under multi-agent environment, and implementation methods of autonomous and cooperation agents. After analyzing the decision steps, decision methods and process in detail, this dissertation proposes the whole framework of enterprise management GDSS based group agent group, department agent group andServer agent group. And fuzzy models and algorithms of task-based GDSS and cooperative negotiation of agents.are presented as well.4. An application system of MAS-based GDSS is build in Qingshan Industry Co. Ltd (Qingshan). This dissertation studies the social, economic and technical background of the emergence of GDSS in Qingshan and proves the necessity of investigating GDSS, and then establishes an actual agent-based enterprise GDSS. Finally, the dissertation concludes with a series of vistas of future enterprise GDSS based on MAS.
