Embodiment 1
[0114] The present invention stipulates that the exponential distribution is denoted as exp(μ), and its probability density function Gamma distribution is recorded as Ga(A,B), its probability density function where Γ(A) is the gamma function,
[0115] The present invention conventionally describes the reliability quality level in terms of the average lifetime t. For both sides of the test (product manufacturer and product user), since the sampling test always has the possibility that the quality of the sample deviates from the overall quality of the product, there must be two risks: the risk of abandonment and the risk of falsehood.
[0116] The risk of abandonment is borne by the manufacturer, which means that the sampling inspection concluded that "the quality of this batch of products is unqualified and rejected", but in fact, the yield of this batch of products meets or even exceeds the requirements of the manufacturer, and the overall quality of this batch of product...
