Test Design Using Expected Failure Times Plot
Four units were allocated for a reliability test. The test engineers want to know how long the test will last if all the units are tested to failure. Based on previous experiments, they assume the underlying failure distribution is a Weibull distribution with <math>\beta</meth> = 2 and <math>\eta</meth> = 500.
Solution
The expected failure time with 80% 2-sided confidence bounds are given below.
