Calculating Prediction Results
Calculating prediction results consists of making the appropriate selections and then starting the process.
1. To open the Calculate window, do one of the following:
◦ On the standard toolbar, click Calculate.
◦ Select > .
◦ Press F8.
2. On the Calculation Selection page, select Prediction. If this checkbox is cleared, prediction calculations do not run.
4. After entering any additional data for other calculations to perform, click OK to run the requested calculations.
The
Calculation Progress window opens, displaying progress as calculations run. When they finish, the
View Calculation Results window opens. If calculations for multiple modules are performed, prediction calculation results appear on a
Prediction Results page. For more information, see
Prediction Calculation Results.
5. When finished viewing results, click Close.
Once you complete this process, you can view results for assemblies and parts in the
System Tree Items table and
Parts Table. You can also see calculation results for system tree items by previewing or printing or print prediction reports. For more information, see
Prediction Custom Graphs. If you selected
Mission calculations on the
Prediction page in the
Calculate window, you can also view mission reliability results. For more information, see
Viewing Mission Reliability Results.

The Telcordia Issue 4, Telcordia Issue 3, and Telcordia Issue 2 models allow you to specify the upper confidence level to use in failure rate calculations. For more information, see Telcordia Issue 4, Issue 3, and Issue 2 Fields. In prior Telcordia and Bellcore models, the upper confidence level is assumed to be 90%, which is also the case for MIL-HDBK-217 models. When using the Telcordia Issue 4, Telcordia Issue 3, or Telcordia Issue 2 model, the default for the upper confidence level is 90%. To use a different upper confidence level, prior to running prediction calculations, specify the value in Telcordia upper confidence level, which appears under Prediction in the System file properties. For more information, see Prediction System File Properties.
