Together with the development of computer network technology, the automatic
collaboration of CIM data activities is becoming an important research iss
ue. Two models are proposed for the research issue: a data activity flow ne
twork model called DAF-Net for coordinating interdependent data activities
and an agent-based integration model of information systems called AIMIS fo
r integrating distributed and heterogeneous information systems on demand.
Additionally, this paper addresses the key design factors of the DAF-Net an
d also the AIMIS: the structural type of the DAF-Net and the agent interact
ion protocol of the AIMIS. Statistical methods and PVM (Parallel Virtual Ma
chine) software are employed for the design of the DAF-Net and the AIMIS.
