Configurable knowledge component technology oriented to product design tasks

Aiming at the problem that accumulated knowledge in product development process could not service the process rapidly, the knowledge component method was introduced and integration methodology based on file was used to construct knowledge component. To reduce the coupling between knowledge component and external task as well as different objects of internal knowledge component, the concept of configurable knowledge component was proposed further. The whole architecture of configurable knowledge component was constructed, and the meta model of it's three internal objects such as input parameters, form and output parameters was built. Meanwhile, the operation mechanism of configurable knowledge component was studied. Configurable knowledge component provided an effective way to integrate parameter, experience and rules in loose coupling mode, thus it could be applied to different design process. The calculation process of engine's air filter development was taken as an example to illustrate the construction, operation and renewal process of configurable knowledge component.
