More Information
Summary:The system receives a stream of tasks which arrive according to some random processes. A new availability measure, random-request availability, is proposed. This stochastic model provides closed-form mathematical expressions which incorporate the 3 basic elements: random task arrivals; system state; and operational requirements of the system. An analytic model is derived and illustrated by numerical examples.
