Zusammenfassung:	The floors at which related notable elevator features occur are compared to determine a floor factor, F, depending on whether the notable feature occurs only at one floor or at more than one floor. Estimated probabilities, P'(S/C), that any component, C, will result in a symptom, S, (where S = first and second notable features in a related group and the accompanying floor factor, F) are provided by experts; the probability of P'(C) of any failure being of any given component is determined from failure history; and an estimated probability, P'(C/S), that system S is caused by component C is given by P ² ( S / C ) P ( C ) P ² ( S / C ) P ( C ) . c
