飞机研制需求管理技术研究

Study on Requirement Management for Aircraft Development

"文档式"需求管理模式已不能满足飞机研制发展的要求。本文结合飞机研制的特点,将飞机研制需求分为功能需求、质量需求和约束需求,并对三类需求间的关系进行了分析;将需求管理分为飞机顶层需求层、主部段/主系统需求层、部段/分系统需求层、部件/设备需求层,并对各层次间各类型需求的演变进行了分析,对需求管理的难点进行了剖析,为实现基于模型的飞机研制需求管理奠定基础。

Document-based requirement management now fails to satisfy the requirements for aircraft development. Based on the features of aircraft development, the aircraft development demand was divided into functional requirement, quality requirement and constraint requirement, and the relationship between them was analyzed. Besides, requirement management was explored from the perspectives of aircraft level, system level, sub-system level and component level. After that, the evolution of all kinds of requirements of all levels was analyzed. Finally, the dififculty in requirement management implementation was discussed. It lays a foundation for the realization of model-based requirement management in aircraft development process.
