To produce a saturation report, click on the Saturation Analysis push button.
Informational messages are displayed in the Session Messages window and model summary reports are written for each iteration of the model. A summary saturation report is written when the iterations are complete. The report names of the model at the currrent load and at 25%, 50%, 75%, and 100% greater load are:
The report names of the model at 25%, 50%, 75%, and 100% less load are:
The name of the overall report is SATURATION.RPT. You can look at the saturation analysis reports in the Report Writer window by selecting Read from the File menu for the window and following the steps for the File Selection dialog box.
To produce a new model, click on the Performance Prediction push button.
