An Analysis of Accuracy of a Procedure for Computing Lower Confidence Limit on System Reliability Utilizing Subsystem Test Data

摘要

Systems which are composed of two or more phases, or subsystems, arranged in logical sequence are found frequently in industry and defense. Standard procedures for computing lower confidence limits on reliability of such systems rely on the use of system data. Engineering changes to any of these subsystems can effect the invalidation of all existing data, necessitating additional, sometimes extensive, testing. Such changes are not infrequent in complex systems. A need exists for a method of computing lower confidence limits on reliability which uses phase data. Some approximation techniques have some available. One such technique is currently being used. Computer simulation techniques are used to analyze the accuracy of this procedure. (Author)
