Abstract:

Several promising techniques of initially estimating and subsequently updating maintenance factors replacement rates for parts in a new system are presented. This factor is an important parameter in the determination of intial provisioning quantities. Distinctions are made between replacements and failures, and between updating maintenance factors and updating demand estimates. The retainability concept is introduced wherein analogs of reliability formulae may be used to obtain initial estimates. Use of family rates for groups of parts is discussed also. Updating schemes utilize variable weighting of past observations, as in Kalman filters. A summary of current practices is included. Author
