Subject: Reliability and Confidence Allocation
In many cases we need to allocate system reliability requirements down to component level. Reliability allocation is quite straight forward by using block diagram; however, what would be a good approach to allocate confidence requirement? If I demostrated reliability at 90% confidence for all components, can I calculate system reliability by using block diagram and claim 90% confidence at system level without system level testing? Any good suggestions, reference?
