摘要

Product lifecycle modelling is to define and represent product lifecycle data and to maintain data interdependencies. To build a complete, reusable and highly consistent product lifecycle information model, the product lifecycle is divided into five stages: requirement analysis, conceptual design, engineering design, manufacturing, and service and support. Accordingly, five stage product models (requirement analysis model, conceptual design model, engineering design model, manufacturing model, and service and support model) are discussed. To integrate all information of a product lifecycle and support networked manufacturing mode, the key elements of product lifecycle modelling are discussed and a framework of product lifecycle modelling is proposed. Further, the relationship and evolvement of product models at different stages are described. Finally, a Web-based integration framework is proposed to support interoperability of distributed product data sources.
