Research on information model for product lifecycle

To build a complete, reusable and highly consistent product lifecycle information model, an integrated system framework of product lifecycle model was proposed. The proposed framework consisted of three parts: process model oriented to product lifecycle, extended enterprise resource model and product information model. .The composition, representation and evolvement of product models at different stages of requirement analysis, conceptual design, engineering design, product manufacturing and service support in product lifecycle were discussed in particular. Finally, an integrated information architecture of three-tier (application tier, service tier and data tier) based on product lifecycle was proposed to support distributed interoperability of product data sources.
