Probability of failure Sample Clauses

Probability of failure. ‌ Once the above described steps are completed, the probability of failure of the rockfall protection gallery is computed based on a Bayesian Probabilistic Network (BPN) approach. The BPN used for the analysis and a screenshot from the program showing the results from the probability of failure analysis are shown in Figure 3.5. The expected value of the unconditional probability of failure E[P(F )] is estimated as: E[P(F )] = E[P(F impact)P(impact detachment)P(detachment)] where P(F impact) is the conditional probability of failure of the rockfall protection gallery given the impact of a rock mass, P(impact detachment) is the conditional probability of the rock mass reaching the gallery given that it has detached and P(detachment) is the annual detachment probability. As mentioned in the introduction section of this chapter, the probabilistic analysis using a BPN approach runs in the background; therefore, almost no expertise in the field of probabilistic modelling is required by the user.

Probability of failure. Based on Similarity Mishap data from similar vehicles might be considered in estimating probability of failure when adequate data are not available on the actual UAS. An assessment must be made of the differences between the baseline vehicle and the vehicle to be tested, and whether or not these differences significantly affect flight performance or controllability. For example, using mishap data for a Manufacturer A UAS might be valid, but using such data for a new Manufacturer B UAS would be unacceptable. 3.3 Estimates from Reliability Studies System safety or reliability assessments based on Fault Tree Analysis (FTA) or Failure Mode, Effects, and Criticality Analysis (FMECA) are basic options for predicting probability of failure when actual data are lacking. Fault trees are useful for analyzing complex components and systems. The FTA is a top-down technique that models failure pathways within a total system. The failures are tracked from a predetermined deficient event or condition to the failure that may be induced. FTAs can be used to identify interrelationships within the vehicle and the support systems and to identify common-cause failures. On the other hand, FMECA can be used to analyze a system or process to determine how reliable the system and its components are, identify potential failure modes, and determine the effect and criticality of that failure and how these factors can be modified to avoid failures and increase reliability. The FMECA is a bottom-up technique for tabulating each system element that can fail
