Integration model and its evolution for product lifecycle

Aiming at integrated and dynamic requirements of product modeling,a product lifecycle integration model was established by combining static model with dynamic model.Static model described product lifecycle information fully from three dimensions of width,depth and granularity,which constituted the three-dimensional status space integrated with lifecycle process,information representation and product structure.Based on this static model,dynamic model depicted product's historical information and dynamic evolution from two angles of version and mapping.General and special processes of version evolution were analyzed,and three mapping methods of process domain,representation domain and structure domain were studied.Moreover,evolution process was formalized.The method had been applied in shock absorber products successfully.
