Abstract:

The purpose of this study was to provide insight into Reliability Worth through quantifying the relative values of reliability activities and their impact on life cycle costs. This study is based on APQ-120 and APQ-113114144 Radar reliability data, spanning only a specific time period of their development, and therefore the findings presented are limited to the equipment configurations included in the data base and the specific time period studied. In-service reported reliability performance data was analyzed for both radar families, the objective being to correlate differences in reliability performance with the equipment reliability requirements and programs structured. Reliability program elements instrumental to the development effort are analyzed to determine relative worth. Considerable emphasis is placed on reliability evaluation testing, parts screening, and equipment burn-in which are identified as major contributors toward achieving demanding equipment reliability performance. This report finds that optimum maturity of radars, prior to deployment, requires extensive and well-directed development effort as an investment measured in cost and time. The report also recognizes and supports the importance of uncompromising contractual incorporation of MIL-STD-781 at applicable airborne stress levels as the principal driving force in establishing and executing effective reliability development effort.
