Question:
The distribution of downtime T for breakdowns of a computer system is given by
where a is a positive constant. The cost of downtime derived from the disruption resulting from breakdowns rises exponentially with T: cost factor = h(T) = ebT Show that the expected cost factor for downtime is [a/(a – b)]2, provided that a > b.
