Abstract
To solve the difficulties in managing lifecycle information on varieties of products in the customer demand diversity and personalization environment, a product lifecycle information management approach based on product family is put forward. A 3-Dimention Product Family Lifecycle Information Integration Model (PFLI2M) is proposed, which is composed of product main structure dimension, product dimension and lifecycle dimension, and the evolution process of the 3 dimensions is discussed. Based on the metadata method, unit information representation of PFLI2M is studied from the physical layer, logic layer, expression layer and the application layer. These methods are applied in lifecycle information management of sealing products.
