Abstract: Considering the requirements for the innovative design of complex product, a comprehensive technology for componential operation was proposed including the technical means applied in enterprise's engineering design data/process. Based on the previously realized technologies for design, such as software registration, parameter parsing and data mapping, a plug-and-play mode for heterogeneous application packages was designed to implement the evolutionary management of the componential operation at different levels. The configuration for implementing componential operation was designed on the basis of MS-COM technique, which is available to implement the management of componential operation by instance and project management with a process template as core. A multi-view framework for EAI was therefore given to implement the trans-project data management in accordance to the process template. The valid of the method proposed was verified via an exemplification of computation of aircraft flight loads.
