【Abstract】 Aiming at the insufficiencies of STEP in the product lifecycle, based on the product data meta-model and the product data integration,a product composing model and a product data classification model were created. And then, the framework for product data supporting the product lifecycle was proposed. Finally, the framework has been validated through an actual product model.更多还原
