The paper develops analog computer techniques for the calculation of time dependent availability. It shows how transient availability problems formerly solved by Markov chain theory along with Laplace transforms and matrix algebra can more easily be solved on the analog computer. The resulting analog technique is then modified to allow for systems with nonconstant failure and repair rates. The nonconstant rates chosen for the purpose of illustration are the bathtub failure rate and learning repair rate curves. Existing methods for transient availability calculation assume that the system operates whenever it is operable and that repairs begin as soon as failure occurs. Many systems have utilization and work force policies which do not meet this assumption. An analog technique is developed in the paper for handling systems of this nature. Author
