Once the new analysis has been defined, and the user has all of the General and Options information selected the way they want, performing the computations is simply a matter of pressing the Compute button at the bottom of the Duration Analysis editor. If the computations are successful, the user will receive a message that says "Compute Complete". At this point, the user can begin to review the results.
Multiple Duration analyses can be computed using the Compute Manager. Select the Analysis | Compute Manager menu option to open the Compute Manager. Select the analyses to be computed and then press the Compute button. Close the compute dialogs and Compute Manager when the program finished computing the analyses.
