Abstract: The aerospace large-scale complex equipment products have diverse types and high complexity. The existing scientific research and production mode focuses on vertical integration, trial production and batch production mixed line production, which leads to difficulties in horizontal collaboration and insufficient batch production capacity. By analyzing the characteristics of mixed line production and final assembly of aerospace equipment products, based on the manufacturing model driven by aerospace final assembly, a unified data model, collaborative mechanism, and standard specifications are established to build a cross enterprise, horizontally penetrating unified collaborative platform for final assembly plants, component factories, and raw material factories. General assembly plants at all levels rely on collaborative platforms to release a complete set of KBOM (kitting BOM) for final assembly. Supporting plants use the collaborative platform to associate and deliver multi-dimensional data such as physical objects, product certificates, QR codes, etc., and use digital pull dashboards to display real-time panoramic data of the entire chain of supporting plants. Explore key technologies such as the technical architecture and security protection of a collaborative platform for aerospace equipment research and production based on cross heterogeneous networks, data standards and routing transmission mechanisms based on heterogeneous collaborative scenarios, and model-based lightweight transmission and parsing mechanisms for a complete collaborative environment, forming a aerospace “main supply collaboration” model with multi-level assembly plants as the fulcrum of the industry chain. Carry out application practices in typical aerospace assembly plants, component plants, and parts factories, streamline the open and collaborative aerospace manufacturing industry chain characterized by lean, digital, networked, and intelligent processes, enhance the overall management level of the supply chain, and promote collaborative innovation and ecological development of the pull production industry chain.
