Failure mode and effects analysis (fmea)
|
A procedure by which potential failure modes in a technical system are analysed. an fmea can be extended to perform what is called failure modes, effects and critical analysis (fmeca). in a fmeca, each failure mode identified is ranked according to the combined influence of its likelihood of occurrence and the severity of its consequences.

Identified, английский
Likelihood, английский
- Вероятность. правдоподобие.
- Правдоподобие; вероятность
- In probabilistic and statistical methods, the likelihood is a measure of the evidence for the data when a hypothesis is assumed to be true. it is commonly used in bayesian and quasi-bayesian techniques. a related measure, minimum message length, can be derived from information theoretic principles. as an example, suppose you observe a data value x that is assumed to be gaussian. the likelihood for that data when the assumed mean is, say, 5, and the variance is 10, is proportional to e-((x-5)2/2*10), the kernel of a gaussian distribution. a likelihood is typically calculated using the kernel, rather than the complete distribution function, which includes the normalizing constants. see also: minimum message length.
Occurrence, английский
- In insurance terminology, an accident or a continuous exposure to conditions which result in injury or damage, provided the injury or damage is neither expected nor intended. ocher, ochre a naturally occurring yellowbrown hydrated iron oxide; used as a pigment in paint and a filler in linoleum. oct on drawings, abbr. for “octagon.”
