The occurrence of a catastrophe makes the system empty instantly but the system takes its own time to be ready to accept new customers. This time is referred to as ¡°restoration time¡±. The aforesaid distribution is obtained as a marginal distribution of the joint distribution of the number of customers in the system at time t and the number of times system reaches its capacity in time t under the conditions of catastrophes and restorations. %K Catastrophes %K Markovian Queue %K Restoration %K Transient State %K Laplace Transform %U http://www.oalib.com/paper/3143526
