Abstract: The combination of human role and computer processing power will greatly improve the efficiency of CIMS application. In this paper, a push-pull model is put forward. By this model, the workflow within and between different subsystems can be integrated. It will make the CIMS application evolving more orderly, thus to create a human-machine coordination environment and fulfill the enterprise strategy aims of winning in the market. The definition and system structure are given in this paper. On this basis, the methods of how to utilize the push-pull mechanism to form a well coordinated environment for CIMS are discussed.
