摘要:Agent-based technology is a new generation of software applications which are capable of handling in real time the complexity of modern business processes. The agents are invested with the intelligence necessary for collecting data,for reasoning about it or for evaluating it,and they are also invested with the authority and the autonomy to act independently. As we know,an agent is independent,because it can act without having to be controlled by the user and it controls its own actions and internal status;an agent is social because it cooperates with man or with other agents in order to fulfill its tasks;an agent is reactive because it is sensitive to the environment in which it acts and it responds in due time to the eventual changes;an agent is proactive because it is able to show a target-oriented behavior by taking over the initiative.
