Introduction of multi-agent and Petri net Introduction of multi-agent The conception of multi-agent The so-called multi-agent system is the collection of many calculable agents and every agent is a physical or abstract entity which can effect both itself and the circumstance and correspond with other agents. The main idea of multi-agent is that a complicated problem should be divided and the portions should be contributed to every independent agent then they compose of the answer to the question. Agent can resolve some local problems independently and finish the whole answer by collaboration. The incompact network is composed of many agents these agents interact with each other to resolve the problems that single agent cannot solve because of its insufficient in ability or knowledge. Its main feature is every agent hasn t sufficient ability or knowledge to resolve the problems when these agents operate at the same time not only the data is incompact but also there s no whole control system. Control structure of multi-agent system Multi-agent is composed of many agents which have the function of circumstance observation task layout and operation. In order to make these agents into a big complicated system to fulfill some stated tasks efficiently a proper control system is needed. Therefore the main research problem of control structure is to design a correct proper local control plan to guarantee that multi-agent system can resolve the given problems efficiently including relevant task distribution correspondence and conflict solution. According to agents relative relations in the system generally there are some kinds of structures 1 2 1 Architecture of fully connected .
