一种基于MBSE的飞行传感器系统需求建模方法

针对传统的基于文档式的需求工程方法无法满足当前复杂系统的需求分析,论文提出一种基于模型系统工程(Model-Based Systems Engineering,MBSE)思想的传感器系统需求建模分析的方法,辅以DOORS工具对需求进行管理。首先,基于DOORS对飞行传感器系统的需求管理进行研究,以支持系统的需求演进,方便后续的需求建模分析;其次,在Rhap?sody环境下采用SysML用例图对飞行传感器系统需求进行静态建模分析,从参与者的角度分析系统需求用例;最后,通过对某型号无人机传感器系统应用实例的分析来验证该方法的有效性和可行性。

A Requirement Modeling Method for Flight Sensor System Based on MBSE

Aiming at the traditional document-based requirement engineering method can't meet the requirement analysis of current complex systems,this paper proposes a method of sensor system requirement modeling and analysis based on Model-Based Systems Engineering(MBSE),which is supplemented by DOORS tool to manage the requirements.Firstly,the requirement man?agement of flight sensor system is studied based on DOORS to support the requirement evolution of the system and facilitate the sub?sequent requirement modeling and analysis.Secondly,the requirement of flight sensor system is modeled and analyzed by using Sys?ML use case diagram under Rhapsody environment,and the use cases of the system requirements are analyzed from participants'perspective.The validity and feasibility of this method are verified by the analysis of an application example of UAV sensor system.
