摘要：
Based on its assumption product lifecycle information system is a dissipative structure, the product information model of different product lifecycle phase is regarded as the main research subject, and the time for establishing accurate and perfect product information model is regarded as the order parameter to describe the order and evolution direction of a system. The dissipative structure theory and grey system theory are applied to establish the determination model based on grey relation entropy and provide new evaluation methods for product lifecycle information system as well as theoretical foundation for system optimization design and adjustment. The model is applied in the evaluation of CAPP system evolution in a company. The feasibility of the evaluation method and the model is verified by the results.
