Probability Assessment of Safety Risk Occurrence Based on Minimum Cut Set Fault Tree Analysis Method
In response to the actual demand for safety risk occurrence probability assessment of weapon equipment,the method of determining the minimum cut set,importance calculation analy-sis and safety risk occurrence probability calculation are introduced in detail.A risk probability as-sessment method based on minimum cut set fault tree analysis is used to evaluate the probability of unexpected action of pin pullers,and the safety risk probability value of the unexpected action of the pin pullers is obtained.Combined with the importance analysis,the key factors causing the un-expected action of the pin puller are determined,and relevant design measures are taken to reduce the probability of safety risk occurrence.
