INVESTIGATION OF THE ACCURACY OF USING STEADY-STATE RESULTS TO APPROXIMATE ACTUAL SYSTEM AVAILABILITY.
Abstract
Values of system availability are computed for a system whose failure density is exponential and whose repair density is special Erlang. The system is modeled as an alternating renewal process. The Laplace transform of the availability function is developed and inverted (by using a numerical procedure) to obtain the values of the system availability. Corresponding values of the long-run average system availability and the average availability over the first mission time are also computed. Comparisons are made which establish that using the long-run average value to approximate the true availability over the first mission time is a conservative practice. (Author)
