Failure Intensity BD

For reliability growth data analysis only.

Description: Allows you to manually build a table that calculates the failure intensity (FI) of every unique BD mode in the data set. This applies only to data sets analyzed with the Crow Extended or Crow Extended - Continuous Evaluation models.

Field Format: [FIBD (Source Number)(Row;Column)]

  • Source Number is the associated data source number.

  • Row corresponds to the order in which the unique BD modes appeared in the data set (i.e., row 1 = 1st unique BD mode that occurred, row 2 = 2nd unique BD mode that occurred, etc.).
  • Column is an index number (from 1 to 3) that returns the following information:
    • 1 = returns the classification and mode.
    • 2 = returns the failure intensity before fixes are implemented at the end of the test.
    • 3 = returns the failure intensity after fixes have been implemented at the end of the test.

Remarks:

  • The Source Number is selected from the Data Source Index drop-down list.

  • The Row and Column values must be greater than 0.

Example:

  • [FIBD(1)(1; 2;0)]
