The organization structure must change to make the organization adapt to the dynamic

autonomy multi-agent system (MAS) environment.Through adding an additional layer in the original MAS

we build a two-level assisted MAS model.The new added layer is in charge of organization adaptation.In order to help the organization

the paper gives the correlation function of organization adaptation.Through the simulation in a peer-to-peer network

it is proved that the proposed model in which an additional layer is added in the original system has better adaptation performance.
