In order to combine components quickly and effective
a method based on agent mechanism which is free of programmed is presented here.Unifying the interfaces of components by being inherited from the same components
using agent component as a middleware to connect the client and the combine components accomplish the analysis
decision-making
coordination and organization of external information.Methods and principle of standardized components
information storage and messaging are given in detail.The example of avionics system simulation shows that the method is feasible.
