In the case study presented in this paper we consider early development phases of a mechanical product. We want to evaluate different concepts and decide which one(s) to pursue. A problem in early phases is that usually no test runs are available. In our case study, based on a standard, there are ways to compute the lifetime distributions of the components(More)
The higher the reliability requirements on a product are, the more extensive the test must be to ensure the required reliability. One is often unable to obtain a reasonable amount of test items, when stresses approximate normal operating conditions. To reduce sample-sizes and test duration components are exposed to much higher stresses during the test than(More)
