Event-based evolution mechanism in dynamic environment for multi-agent system

As Agent-based software development methods get more and more attention and Agent-based software system has been used in a variety of occasions, the features and advantages of Agent have been recognized by scholars. However, the runtime environment of Agent is dynamic, open and changeable; runtime in this kind of environment is a big challenge to ensure that the software system can satisfy the user´s requirements and is proper in continuous running. An event-based evolution mechanism in dynamic environment for multi-agent system was proposed. Taking advantage of the Agent´s characteristics such as autonomy and intelligence, the evolution mechanism can satisfy the requirements of user´s and support software upgrade in dynamic environment by means of software evolution. By the proposed mechanism, the Agent could autonomously cooperate with others to complete the task. Finally, an experiment of the mechanism was presented to verify its effectiveness.
