System Reliability Demonstration Considering Uncertainty of Prior Knowledge

Today's products are equipped with a wide range of functions and components. This enables the necessary competitiveness in times of digitalization, but also causes a large number of potential system failure causes. The validation of such systems and especially the demonstration of system reliability is a challenge. With available prior knowledge, an efficient validation strategy can be achieved by combining different test types and different test levels, such as system, subsystem, component and unit tests, using the concept of Probability of Test Success and Bayes' theorem. In doing so, the available information is used comprehensively and according to its quality for planning the validation tests.
