For a parallel system with dependent components following the ELS rule, assuming the component stress proportionality correction coefficient equals 0.9, the expected values of the time until successive exceeding the reliability critical state, are much worse than in case of the system with independent components. Namely, for a system composed of 5 components these values are less by 61%. This difference is still increasing as the number of system components increases, and for a parallel system consisting of 10 components is 69%.
As a second case, we consider this parallel system as a repairable system with non-negligible renewal time, and assume that the expected value of system recovery time to the reliability state 3, 2, and 1 after exceeding ...
