영문 초록

FMECA is one of the useful engineering tools for examining the potential failure modes within a system and its equipment and also for determining their effects on equipment and system performance. For CA (criticality analysis) procedure, β-value (the failure effect probability) should be estimated properly for an accurate identification of the critical items of system. In real applications, however, a subjective judgement of β-value is usually adopted. In this study, some guidances on the proper uses of β-value are considered. An alternative method for estimating β-value based on conditional probability is suggested and an illustrative example is given.
