Abstract: Aiming at practical requirments of present project management and control,the paper presented to construct integrated multi-object trade-off model based on project process management,so as to actualize integrated and dynamic trade-off of the multi-object system of project.Based on analyzing basic principle of dynamic controlling and integrated multi-object trade-off system process,the paper integrated method of cybernetics and network technology,through monitoring on some critical reference points according to the control objects,emphatically discussed the integrated and dynamic multi-object tradeoff model and corresponding rules and mechanism in order to realize integration of process management and trade-off of multi-object system.

Key words: project management, process management, multi-object, dynamic trade-off, trade-off mechanism
