A Manual for Calculating Confidence Limits on Equipment Availability. Volume III

摘要

The availability of an equipment is defined as the probability that the equipment is operating satisfactorily at any point in time. The document describes manual procedures for calculating at any confidence level, confidence limits on the availability of an equipment from test data. Two cases are considered: When both times-to-failure and times-to-repair follow the exponential distribution; and, When the times-to-failure follow the exponential distribution and the times-to-repair follow the lognormal distribution with a known shape parameter.
