IMPROVING DESIGN FOR RELIABILITY (DFR) PROCESSES USING MODIFIED CROW EXTENDED RELIABILITY GROWTH MODEL METRICS

摘要

This article deals with reliability growth that can be achieved prior to the occurrence of failures that are "discovered" during testing or subsequent customer use. The definitions of A-modes (failure modes in design that will not be mitigated) and B-modes (failure modes in design that will be mitigated "immediately" (BC-modes), or delayed (BD-modes)) that occur during testing have been developed by others as a means for measuring reliability growth, and projecting reliability growth potential, during the Developmental and Operational test phases of military systems.
