Reliability Demonstration Calculator Fields
Specify the following quantities and test settings:
Alpha
The probability of a type I error, which is the probability of rejecting the null hypothesis when it is true. It is commonly referred to as the significance level of the test. The default alpha level is 0.05.
Distribution
–
The assumed failure time distribution. Distributions available are: Weibull, Lognormal, Frechet, Loglogistic, SEV, Normal, LEV, and logistic. For more information about these distributions, see
Statistical Details for the Life Distribution Platform
in the Reliability and Survival Methods book.
Scale
The scale parameter for the failure time distribution.
Note:
The Scale field is denoted Weibull
β
when the specified Distribution is Weibull.
Max Failures Tolerated
The maximum number of failures allowed for a successful test demonstration.
Reliability Standard
The definition of the standard that you are testing. This standard is based on a length of time and the probability of an items survival to that time.
Time
The minimum length of time that an item under test should survive.
Probability of Surviving
The probability that the item under test survives until the defined Time of the reliability standard
Enter one of the following two values to calculate the other:
Time of Demonstration
The length of the demonstration in time.
Number of Units Tested
The number of units needed for the demonstration.
