Abstract: As a problem solving structure, agent organization can be used effectively to reduce the difficulties of problem solving and complexity of interactions between agents. Abstracts agent organization include structure, rules and patterns, so that the rule generation of an agent organization is an important issue for the agent organization formation. In this paper, a mechanism of agent organization rule description and generation is given, and the static and dynamic algorithms of agent organization rule generation are designed. It is an improvement to Zambonelli ＆ Jennings’s work about abstract definition of agent organization rule.
