Once the design of a complex system has been finalized and the reliability of key components has been determined, it is important to develop a sparing process to achieve maximum system availability. Ideally, increasing the number of spare components increases system availability, but due to cost considerations, this is not the means to obtain a feasible solution. The question of how to optimize the number of spare components is further complicated when the repair cycle of failed components is taken into account.
