摘　　要：针对基于文档的系统工程(Text-Based System Engineering,TSE)方法在民机综合监视系统研制上存在的表达模糊和效率低下等问题,提出了采用基于模型的系统工程(Model-Based System Engineering,MBSE)方法进行系统设计,并在此基础上对MagicGrid方法进行改进。首先,依据改进MagicGrid方法的建模步骤进行系统架构建模。然后,提出了一种SysML与Simulink/Stateflow协同仿真机制来弥补SysML语言仿真能力弱,以及无法描述系统连续动态行为的不足。最后,以综合监视系统的子系统近地告警系统(Ground Proximity Warning System,GPWS)为例,对系统动态行为进行了仿真验证。结果表明:使用改进MagicGrid方法进行系统架构建模以及采用协同仿真对模型进行验证,能够提高系统设计的效率和准确性。In response to the problems of vague expression and low efficiency in the development of civil aircraft integrated surveillance system using the Text-Based System Engineering(TSE)method,Model-Based System Engineering(MBSE)method was proposed for system design,and improvements were made to the MagicGrid method based on this.Firstly,the system architecture based on the modeling steps of the improved MagicGrid method was modeled.Secondly,a collaborative simulation mechanism between SysML and Simulink/Stateflow was proposed to compensate for the weak simulation ability of SysML language and the inability to describe the continuous dynamic behavior of the system.Finally,taking the Ground Proximity Warning System(GPWS),a subsystem of the integrated surveillance system,as an example,the dynamic behavior of the system was simulated and verified.Practice has shown that using the improved MagicGrid method for system architecture modeling and using collaborative simulation to validate the model can improve the efficiency and accuracy of system design.
