Moreover, the probability adaptation was performed at regular intervals to estimate the probabilities of ED failure, and the occurrence probabilities of consequences caused by ED failure.
The posterior failure probabilities of safety barriers were utilized in the third phase and were fed into event tree branches to estimate the updated occurrence probabilities of consequences.
For a given option, the expected cost is the sum of costs of each consequence weighted by the probability of that consequence.
The probability of a consequence of n flips (P(n)) is 1 divided by 2n, and the 'expected payoff' of each consequence is the prize times its probability.
For instance, regarding x o ("inadequate for use, inadequate sensibility, inadequate spatial resolution") the probability of each consequence (p 0 - p 7 ) if the action is to reject (a 0 ) the film can be obtained from Table 2.
However, models and simulations that provide the ability to conduct multiple, iterative test runs of system performance in operationally relevant scenarios should be able to provide designers with useful information about the probabilities of various adverse consequences, possibly even illuminating hitherto unforeseen, unintended consequences.
Only time of day is related to accident severity with off-peak hours during both day and night increasing the probability of direr consequences for all persons involved in general and bus passengers in particular.
Women were found to rate the probability of negative consequences in extreme sports significantly more likely than men [22], which is believed to explain in part a lower life expectancy in men [23].
Safety level is dependent not only on technical process parameters that have immediate effects on the 'frequency' or probability of catastrophic consequences, but also depends on equipment integrity degradation, operational and management quality, attitudes, and cultural processes which may change over a prolonged time.
