Reliability Acquisition Cost Study
Abstract
This report presents the results of a study to develop basic relationships capable of determining and predicting the acquisition costs attributable to equipment reliability. The study is based on data derived during the development phase of equipment acquisition. The relationships, including incremental reliability gain related to incremental reliability cost, were developed using data from two manufacturers on ten equipments covering three reliability environments. The equipments cover a span of end use airborne and space environments. The reliability elements analyzed in the study are the reliability design program (includes prediction, failure mode and effect analysis, and design reviews); the reliability parts program (includes parts screening specification, parts standardization and control, and vendor control); and the reliability testing program (includes evaluation testing, equipment environmental screening, and reliability demonstration testing). To develop the relationships, two linear models were hypothesized. The first model relates resultant equipment reliability, the reliability costs and the equipment complexity. The second model relates incremental reliability element gain to reliability element cost. Detailed discussions of data collection and analysis efforts along with step-by-step procedures for using the modeling results are presented in the report. Contraints and precautions to be applied in using the equational relationships are also included.
