Abstract :
In safety-critical systems, components must be highly reliable. Once a component´s reliability is lower than the criterion, it will be replaced and transferred to be used in another system which does not need such high reliability. The safety virtual age criterion not only relates with the cost of repair actions, but also with the repair degrees and the systempsilas wearing degrees. In this paper, we considered different repair degrees and studied the best safety virtual age criterion to minimize the cost. Finally some numerical examples are presented to illustrate the results obtained in this paper.
