| Planning and evaluation of reliability demonstration testing with uncertainties |
|---|
| During the development of products, the proof of product reliability is often a challenging activity. Basic planning actions have to be executed in an early design stage of the product. First of all, two possible ways for the proof of reliability are available: testing without failures and testing with failures. Within the framework of this work, the focus will be on testing without failures, also called reliability demonstration testing (rdt). At the planning phase, the following questions have to be analysed: • What is probability of a successful rdt? • Which number of specimen and testing duration is necessary? • How to handle the unlike event of product failures while performing a rdt? • Which uncertainties have to be regarded and how to consider in the evaluation phase. Especially uncertainties and their consequences are part of this study. One example is the estimation of the shape parameter of a Weibull distributed failure characteristic in the planning phase. Possible sources for the estimation and the consequences of uncertainties of the estimation are analysed. After performing a rdt, the impact of uncertainties on the results are under consideration. The effects of uncertainties of the planning phase, e.g. uncertainties of the estimation of the Weibull shape parameter, to the demonstrated reliability and the confidence level are shown. Finally, case studies give an impression of the importance of the uncertainties. Some hints for the practical implementation close the whole topic. |
