Document Summary
Rs = r1 * r2 * r3 * * rn. Find fr(%) = # of failures * 100% Total operating time = # of units tested *# of unit hours. Non operating time= total hours of testing when they failed. Non operating time = add all non-operating time. Operating time = total time non-operating time. Fr(n) = # of failures_ [# of failures/unit hour] Failure rate * x amount of stuff = how many would expect to fail. Acceptance sampling is the process of evaluating a portion of the product in a lot for the purpose of accepting or rejecting the entire lot. Acceptance sampling is most effective when it is preceded by a prevention program that achieves an acceptable level of quality of conformance. Reduced monotony & inspection error rejection of entire lot rather than sorting of defectives tends to emphasize quality issues. Proper design of sampling plan requires knowledge of the quality level requirements.
