A vital feature of engineering and systems design. Often now called FMEA, Failure Mode and Effects Analysis.
a) For example, 'what if today's computer backup is not available?'.
Should lead you to multiple backups, off-site storage, and so on.
b) Many industrial machines, from cooking fryers upwards have heaters on all the time, controlled by a thermostat. Q 'What happens if the thermostat sticks in the ON position?'.
Should lead you to a separate thermal measurement, independent of the first, and so on up to automatic cooling/fire suppression systems.
The Failure Mode, is a different set of thinking tools, to those of Effects Analysis.
The acronym DFMEA stands for "Design Failure Mode Effects Analysis". DFMEA is an extension of Failure Mode and Effects Analysis which attempts to estimate the frequency and severity of each failure mode.
can anybody help me with this.
DFMEA stands for design failure mode and effect analysis.
I depends what you need the analysis for
Does anybody know of a good Doctor? Is there anybody out there!? Who ate the last muffin? It could have been anybody! It's anybody's game! Anybody can be an actor!
I Don't Know Anybody Else was created on 1990-12-18.
anybody know?
no
DOES ANYBODY KNOW????????????????
PFMEA is also called potential failure mode effects analysis. The purpose of PFMEA analysis is to take actions to eliminate or reduce failures, starting with the high priority ones.
They know thing from there brain.
