民用飞机预研论证权威真相源构建技术

权威真相源不仅是基于模型的系统工程实施的核心要素，也是"数字工程战略"的关键环节。对权威真相源构建技术进行了研究，包括对权威真相源进行了定义和分析，设计了权威真相源的构建目标和原则，构建了权威真相源的架构和业务流程，并对构建权威真相源的支持技术进行了研究。梳理了民用飞机预研论证的业务流程、专业模型和基础模型，最后通过民用飞机预研论证验证机的案例研究，证实了权威真相源构建技术的可行性。民用飞机预研论证权威真相源能够有效提升系统工程的组织性，提升协同设计效率，同时能够提高模型和系统设计的重用性，减少系统工程实施的复杂度，缩小开发成本。

Construction technology of authoritative source of truth for civil aircraft pre-research

The authoritative source of truth is a key component of the "Digital Engineering Strategy" as well as the core element of model-based system engineering implementation. The construction technology of an authoritative source of truth is researched, which includes defining of the concept of authoritative source of truth, establishment of the goals and principles, and design of the architecture and business processes. The supporting technologies for constructing the authoritative source of truth are also studied, and the business processes, professional models, and basic models of pre-research of civil aircraft sorted out. Finally, a pre-research case study of a civil aircraft confirms the feasibility of the technology. The authoritative source of truth can effectively improve the organization of system engineering, enhance the efficiency of collaborative design, increase the reuse of models and system design, and reduce the complexity of system engineering implementation and development costs.
