Superposition System

For reliability growth data analysis only.

Description: Allows you to manually build a table that shows the failure times on the timeline of the superposition system. This applies to the Repairable Systems data type only.

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

• Source Number is the associated data source number.

• Row corresponds to the order of the data points on the timeline of the superposition system, as shown in its System Operation plot (i.e., row 1 = 1st failure, row 2 = 2nd failure, etc).
• Column is an index value (from 1 to 4) that returns the following information:
  • 1 = returns the failure time.
  • 2 = returns the cumulative number of failures.
  • 3 = returns the mode classification (for the Crow Extended model only).
  • 4 = returns the failure mode (for the Crow Extended model only).

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:

• [SUPERSYSTEM(1)(5;2)]
