Existing maintainability prediction techniques are not accurate estimators of current electronic equipmentsystem characteristics. A new time synthesis prediction technique is developed which directly relates diagnostic isolationtest subsystem characteristics and other design characteristics to equipmentsystem maintainability parameters. The developed methodology includes a detailed prediction procedure for use when final design data is available, and an early prediction procedure for use when preliminary design data is available. Predicted parameters include mean time to repair, maximum percentile time to repair, maintenance man-hours per repair, and fault isolation resolution. Also included is a comprehensive set of time standards applicable to physical maintenance actions associated with current construction and packaging techniques.
