Subject: Confidence Limits on Reliability Predictions
Message:
Question: I have been asked about confidence limits on failure rates calculated using MIL-HDBK-217 & Bellcore, using the NPRD and vendor data. My experience in determining confidence limits is based on statistical type testing as described by MIL-STD-781 and not based on the reliability prediction. The requestor is continuing to state that you can determine confidence intervals on reliability calculations without test data. Do you know of a method, or a publication that would help? I thought at one time there was a paper written concerning confidence limits on the formulas presented in MIL-HDBK-217 since these formulae are based on test data of components?
