Webwhere W (t) is the cumulative intensity function (CIF) that is a function of time. Assuming that the system is continuously impacted during its operation, the level of each impact is related to WCs. The probability of failure is related to the cumulative damage within a certain period. The increment of cumulative damage means an increased ...
