Design of collaboration framework for distributed CIM data activities

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