Modify the Confidence Level for a Reliability Distribution Analysis

The Confidence Level specifies how the optimistic and realistic scenarios will be selected in a Monte Carlo Simulation for TTR Distributions in an analysis. The Confidence Level indicates whether the distribution is within the confidence limits or not. The default Confidence Level for an analysis is 90 percent.

You can modify the Confidence Level in the Analysis Summary workspace or after selecting any of the plot tabs in the left pane.

Steps

  1. Access a Reliability Distribution Analysis for which you want to modify the Confidence Level.

  2. If you want to modify the Confidence Level in the Analysis Summary workspace:

    1. In the bottom section, select Distribution Options, and then select .

      The Confidence Level box is enabled.

      Note: If the Confidence Level box is disabled, select the Use Confidence check box to activate the Confidence Level and enable the Confidence Level box.

    2. In the Confidence Level box, enter a numeric value between zero (0) and 100 to represent the desired Confidence Level, and then select .

      The GE Digital APM system displays the confidence intervals for the analysis based on the percentage you entered in the Confidence Level box.

    If you want to change the Confidence Level after selecting one of the plot tabs (e.g., Probability Plot tab):

    1. In the left pane, select the Probability Plot tab.

      The Probability Plot appears in the workspace.

    2. In the upper-right corner of the workspace, select the Distribution Options list, and then select Confidence Level.

      The Set Confidence Level window appears.

    3. Select the Use Confidence check box to activate the Confidence Level and enable the Confidence Level box.
    4. In the Confidence Level box, enter a numeric value between zero (0) and 100 to represent the desired Confidence Level, and then select OK.
