摘　　要：针对传统系统工程存在的迭代周期长、开发效率低、模型二义性等问题,结合基于模型的系统工程理念,将敏捷系统工程概念引入到民机研制过程中,并利用系统建模语言定义了基于场景的功能建模方法,详细分析了民机自动飞行控制系统高度控制用例的顶层功能愿景,建立了对应的功能模型和接口描述视图。该方法以迭代的形式展开系统功能建模,能够充分保证需求和功能模型紧密结合,正向构建满足民机系统以需求为导向的功能建模方法,为民机系统的架构设计工作提供基础。Aimming at the problems of long iteration cycle,low development efficiency and model ambiguity in traditional systems engineering,and combining model-based system engineering,the concept of agile system engineering is introduced into the civil aircraft development process,and the system modeling language is used to define a scenario-based functional modeling method.The top-level capability vision of the altitude control use case of the civil aircraft automatic flight control system is analyzed in detail,and the corresponding function model and interface description view are established.This method expands the system function analysis in an iterative manner,which can fully ensure the close integration of requirements and functional models,and is constructing a requirement-oriented functional modeling method that meets the requirements of the civil aircraft system,providing a basis for the architecture design of the civil aircraft system.
