ABSTRACT:
A method to achieve perceived reliability for repairable systems including goal setting of different phases of the product life cycle. The method includes consideration of a plurality of product life cycle phases to determine a plurality of failure rate multipliers which are transformed to mean time between failures multipliers and normalized. Using these computed mean times between failures multipliers and a chosen level of customer use, the box-of-parts required mean time between failures level can be calculated. Also, the required mean time between failures for design, manufacturing, infant mortality, and service phase of product life cycle can be computed.
