Abstract:

When modeling the reliability of complex systems, many different data sources, from full-system tests to component quality assurance measures to accelerated test data, can be utilized to improve system and component reliability estimates. While much of the previous work has focused on developing a working model for existing data, this talk considers what data collection strategies would be most advantageous for optimizing system reliability precision in the future. A metric to quantify good performance of future analyses is specified. Using this metric, the strategies for determining which data should be collected are dependent on current data available, the reliability of individual components and the relative cost of new data sources. A simple example will illustrate the approach.
