Test-Fix-Find-Test Data Reference Example

This example compares the results for test-fix-find-test data.

MIL-HDBK-189A, Section 7.5.2, pg. 206, 2009.

The following table shows the data.

The book has the following results:


 * Beta = 0.9103, Lambda = 0.2397


 * DMTBF = 7.84 hours


 * BD Mode Parameters: Beta = 0.7472, Lambda = 0.1820


 * PMBTF = 11.29 hours

In RGA, the Crow Extended model with the maximum likelihood estimation (MLE) method was used to calculate the results.


 * The model parameters are:
