Hi, Gurus,
Attachment is one MTBF picture searched in the Chinese webpage.
There is an example in the picture:
Say confidence=90%, and MTBF=300 hours, and failure number is 3,
then
T=0.5*(X0.9(2*3+2))^2*300=524 hours.
Here what confused me is how can they calculated 524 hours?
What does X mean? Integration?
Best,
Tony Liu
