Application Research Of MAS Technology

MAS (Multi-Agent System) is a newer branch in computer science, it has merged and expanded such a lot of ideas of fields as Object-Oriented technology, distributed calculation, artificial intelligence, etc. This dissertation is along the thinking of "MAS theory -> MAS realization technology -> Apply MAS technology to the expert system of wastewater treatment -> The realization of MAS expert system of wastewater treatment" to introduce the achievement concluded in the subject study. First, the dissertation introduces the current development situation, application category of MAS, and the purpose of subject, and the work which the author do in this subject; Then, it introduces the basic conception of Agent, understanding of MAS, and relationship with other computer research fields; Later, it introduces the Agent communication, conflict solution, task collaboration which are most active and important in the MAS field comprehensively and detailed. The author introduces FIPA relevant theories in detail in the dissertation; Then, makes an introduction to several important classes in JADE (a MAS developing platform for JAVA that totally follows FIPA standard). It is an important component of this subject to apply MAS technology to the actual project. According to characteristic of question field that it is appropriate to use MAS to solve, Author applies MAS to wastewater treatment and achieves some better result. The overall design plan of MAS expert system of wastewater treatment are provided in detail in the following content of the dissertation. In the following implementation of MAS expert system of wastewater treatment, author explains three Agents that are already implemented at present: data service Agent, conflict solution Agent and troubleshooting Agent from inside data flow chart to programming one by one, otherwise some key code are provided. Before this, author presents the instance to the communication between Agents. Through the test of MAS expert system of wastewater treatment prototype, the dissertation proves the superiority of MAS technological that this subject study and the correction of application technology route, tools and methods. Meanwhile, the dissertation proposes one intellectualized solution blue print in the field of intellectualized control of wastewater treatment that is provided with self-adaptation, reasoning to solve complicated problem that can be only solved by expert, and the blue print is provided with innovation. In addition, the defect, deficiency and their improving proposition of prototype are provided. Because the Agent theory and relevant standards are under developing, also limited by research level and condition at the same time, there are a lot of question failed to discuss deeply. But the exposition of MAS theory, introduction and exertion of FIPA, successful application in the expert system of wastewater treatment, and discussion of some developing tools (such as JADE, JESS, Hibernate) provide a intact technological route for deepening, extensive research of MAS application technology, and for the realization of MAS. The thought, method involving in this dissertation, can offer a kind of new feasible thinking and reference for the study of open and integrated distributed intelligence system.
