Abstract

A method is given to increase the cost-effectiveness of spares pools by performing repairs of each type of module on a priority basis whenever the number of available spares falls below a critical level. For a system already operating with established spares pools, the problem of choosing the critical levels is solved by an algorithm which attains the largest possible uptime ratio (UTR) for any specified total amount of priority repairing. Provisioning of new spares in conjunction with priority repairing is also optimized so as to achieve any UTR goal with minimum cost. Examples are given to show that even a small amount of priority repairing can yield a substantial reduction of sparing costs.
