System 3: B1 B2 b) Assume the failure rate per hour for each of the components in System 3 is λ = 0.2.104. > Calculate the probability that component A fails during the first year of operation, i.e., before t= 8,760 hours. c) > Calculate the reliability of System 3 for the first year in operation using the factoring algorithm with i=B2: h(p(t)) = P82 h(182 P) + (1-P82) h(082 P), where p-pi(t). d) Assume System 3 being a safety system, where main components B1 and B2 both are passive items tested at T = 0.5 [years]. Both components are repaired (replaced) together and immediately if a failure is detected under testing, but are not repaired (replaced) between the tests, regardless of whether the items fail to function on demand. The detection and repair times can be ignored. > Calculate the probability that a component that has not yet failed is replaced at time t. The failure rate is given in 3b). e) The other two components in System 3 (A and C) are control equipment continuously reading signals; and are running to failure. If there is a failure on one of these, the one is repaired (replaced) at time of failure (immediately after the failure). Given the maintenance strategy described in 3 d) and e), assume that any replacement of a component in System 3 has an expected cost E[CR] =2. > Express the expected replacement cost per test interval t for the system when the failure rate is A.
