基于SysML的航电系统架构安全性评估方法
SysML-based Avionics System Architecture Safety Evaluation
摘要
Abstract
Aiming at the problem that existing analysis methods for system safety separate the processes of system design and safety assessment, a SysML-based avionics system architecture safety evaluation method is proposed.At first, the physical architecture of the system is modeled based on SysML with Enterprise Architect.Then critical information about the system is refined from the XML document of the SysML model, based on which fault trees are established.Finally, after analyzing fault trees, system failure probability and zone safety are obtained.This process is conducted in an automatic safety assessment tool.A display system in IMA architecture is introduced as an example for conducting this method, which verifies the effectiveness of the proposed system architecture safety assessment tool.关键词
