A Research Of Modelling Methodology For Agent-oriented Requirements Engineering

In computer science research, Requirement Engineering and Agent-oriented Software Design are both hot topics. As a more abstract modeling technology, Agent poses a challenge to traditional software requirement analysis method, meanwhile it brings about improvement. In traditional requirement analyzing technology (object-oriented and structure-oriented), the step of requirement analyzing and the program design usually go through the way of disjointing. Nowadays, most of the researches on multi-agent system focus mainly on the infrastructure of MAS, but scarcely on the application system development based on such requirement engineering as early requirement engineering, late requirement engineering, and requirement modeling. Although some agent-oriented requirement modeling methods have emerged at present, they aren't very comprehensive and some other aspects have not involved yet. This thesis poses a quite comprehensive agent-oriented requirement modeling method.First of all, this thesis introduces the modern demand condition of agent-oriented systems. With the development of information society, the demand of software intelligence from society is increasing. Thus, it is a tendency that people research and develop software based on agent-oriented ideas and theories.Secondly, this thesis defines some diagrammatic symbols of agent-oriented system. Among the illustrations of these symbols, it is quite obvious to show various kinds of dependent relationships among the shareholders of the whole system. Then based on that, this thesis also defines multi-agents' interative and collaborative modes, and depicts in detail the multi-agents' communication with each other.Thirdly, it goes on to research the non-functional problems of agent-oriented requirement, problems unavoidable in the agent-oriented system implementation. With the basis of perfection and improvement on former theories, the thesis build non-functional object tree for the non-functional problems with the refining and correlation depicting methods. Some fuzzy, general, holistic non-functional problems could be refined into some sub-problems, which could be resolved easily.Fourthly, this thesis researches on the non-determinate problems of agent-oriented requirement. Introducing the classical rough-set and fuzzy theories and combining the advantages of them, this thesis quantitatively analyzes and describes...
