I have a list of components with their reliability, for example
Resistor [Fixed, Metal Film], Number used 168, Rating 50%, Failure rate 0.005, weighting factor 1.5.
I have calculated the total reliability for all of these components, for the example I think it is 1.26. The next step is M.T.B.F, reliability over 5 days and over 28 days of 8 hour use.
I am currently a little confused as to what I should be doing with these figures I have worked out, do I add them? Multiply them? and then what?
Please help.
