It requires only the knowledge of all minimal sets of components needed for successful system operation. It does not rely on any series, parallel or bridge structure but is applicable to the most general redundant systems. The scheme can be truncated at any level of recursion to yield good approximations. Included is a discussion of how the level of truncation depends on the number of system components, their availabilities and the desired accuracy. (Author)
