Consider a parallel system consisting of two independent components whose time to failure distributions are exponential with parameters μ1 and μ2, respectively (μ1 ≠ μ2). Show that the time to failure distribution of the system is not IFR.
Answer to relevant QuestionsFor Prob. 25.5-4, show that the time to failure distribution is IFRA. Consider a system consisting of five components, labeled 1, 2, 3, 4, 5. The system is able to function satisfactorily as long as at least one of the following three combinations of components has every component in that ...Consider a harbor with a single dock for unloading ships. The ships arrive according to a Poisson process at a mean rate of λ ships per week, and the service-time distribution is exponential with a mean rate of μ ...Follow the instructions of Prob. 26.3-1 for the following waiting-cost functions.
