Availability assessment of avionics display system based on fuzzy fault dependent matrix
The unstable voltage from the power supply modular in the avionics display system may cause errors or loss of subsequent calculation modules. Such fault causal relationship is uncertain and cannot be described by traditional safety analysis methods. This paper extends the safety method based on fuzzy fault dependent matrix, expresses the fuzzy rate as a triple, and recommends using the worst estimated probability value as the availability estimate to ensure that the safety design can meet the requirement. This extended method is also used to analyze the availability of the displaying airspeed function of the avionics system, and the safety design of the model is verified.
