Abstract: Owing to the fact that as yet the mode of the management of process equipment applied in coal preparation machinery enterprises still remains mostly at the artificial stage, the problems faced by such enterprises involve the possibility of making only scatter storage of information and the inability to realize timely and effective data sharing and coordination. To tackle these problems, an appropriate process equipment management scheme is developed based on the successful practice of the produce lifecycle management(PLM) mode. With the application of this management scheme, it is made possible to exercise unified management of equipment design, bill of materials(BOM) and modifications, allow the process equipment management to be made in a standardized, transparent and high-efficiency manner, ensure the consistency, integrity and traceability of data, help improve production efficiency and product quality, and enhance the market competitiveness of the enterprises.
