摘要

Reliability testing is typically used in demand-based systems (such as protection systems) to derive a confidence bound for a specific operational profile. To be realistic, the number of tests for each class of demand should be proportional to the demand frequency of the class. In practice, however, the actual operational profile may differ from that used during testing. This paper provides a means for estimating the confidence bound when the test profile differs from the profile used in actual operation. Based on this analysis the paper examines what bound can be claimed for different types of profile uncertainty and options for dealing with this uncertainty. We also show that the same conservative bound estimation equations can be applied to cases where different measures of software test coverage and operational profile are used. (C) 2016 Elsevier Ltd.
