Consider a consecutive-2-out-of-n: F system. What is the
MTTF if the components are independent and identically distributed, i.i.d. and
each has a constant hazard rate _?
1. A system consists of three components that are
connected in series with four components in parallel. The components are
identical and the failure rate of each component follows a Weibull model with
parameters _ = 1.2 and _ = 1.5 × 105. Derive a reliability
expression for the system. What is the MTTF and the effective hazard rate of
