nformation exchange and sharing are difficult in manufacturing process for manufacturing enterprises, especially for aircraft manufacturing enterprises, which have complex product to fabricate and mass information to handle. To solve this problem, a Single Enterprise BOM (SEBOM) based Aircraft Manufacturing Process Management System (AMPMS) is promoted to support the whole process of aircraft manufacturing, based on the analysis of aircraft manufacturing process and the process of data flowing. In AMPMS, in order to satisfy the information requirement, a SEBOM is established by unifying various BOM data. A unified SEBOM management platform is established to managing distributed and heterogeneous SEBOM data. Furthermore, the key technologies including BOM data mapping and BOM data agent management are discussed in detail. The validity and feasibility of AMPMS system are verified by developing a prototype system.
