A Study of the Role of Modules in the Failure of Systems
Abstract
Since the introduction of the concept of coherent systems and the description of the reliability of such systems in terms of the reliabilities of the components, the concept of importance of a component has created a new and fruitful area of research. Two distinct concepts of importance can be found in literature. For a recent survey on this topic see Boland and El-Neweihi (1990). Birnbaum (1969), Natvig (1985), Boland, El-Neweihi and Proschan (1988), and others considered the improvement in the reliability of the system which comes from the improvement of the reliability of a component, (which can be brought about by directly increasing the reliability of the component, or by augmenting it in other ways) as the importance of that component. Fussell and Vesely (1972) and Barlow and Proschan (1975) on the other hand, defined the importance of a component to be probability that the failure of the component or a module that is part of a system can be derived directly from the role of the component or the module in the failure of the system.
