Abstract
FHA and PHA are two common methods applied in analysis of system safety. However, the two methods have some problems such as to omit hazard analysis or control solution. Meanwhile it is not practical and not effective to deal with enormous work manually in safety analysis. This paper proposed a cross-verification method, developed a tool and applied it to undercarriage which is a typical safety-critical system. The result showed it can make up the omitted work by cross-verification in views of function and hazard instead of independent analysis method. This method can improve the process of safety analysis and enhance the safety of undercarriage system. At the same time, the visual tool can increase the efficiency and usability of system safety analysis.
