Problem 8

Consider an approximation for the CTMC model of Example 8.21 where thedelay state is replaced by an instantaneous branch point. Using the techniqueof Example 5.4 or using equation (5.30). Show that the coverage probability is/( + ). Solve the reduced model and obtain an expression for the error ofapproximation in steady-state availability.9. Modify and solve the CTMC of Example 8.23 so as to introduce transient faultsthat are treated by a retry. Resulting CTMC will have an arc leading from state1D to state 2 at the rate r where r is the probability of transient restoration.Clearly, the arc from state 1D to 1C will now be relabeled as (1 r c).
