Availability of Maintained Systems

Abstract

Availability appears to be a more appropriate measure than reliability for measuring the effectiveness of maintained systems because it includes reliability as well as maintainability. This thesis is a survey and a systematic classification of the literature relevant to availability. Emphasis in this thesis is centered on a variety of topics related to availability. The topics discussed are: the definition and concepts of the availability, the probability density functions of failure times and of repair times, system configurations; and the various approaches employed to obtain the availability models; effect of preventive maintenance policies on availability; availability parameters in the model; and system optimization.
