4.14. Performance Index

The user should measure the performance of your design to analyze the results of design study. A Performance Index is defined as a function expression.

Figure 4.164 Performance index List dialog box

• No: Shows the number of Performance Indexes.

• Use: If you check this option, the DV is used by the DOE.

• Name: Specifies the name of Performance Index.

• Description: Shows the description of Performance Index.

• OutputType: Shows the type of output. Output type can be defined as one type among Expression, Scope, and ProcessNet.

• Output: Shows the name of output.

• Treatment: Choose the type for Performance Index. It is seven types that are End Value, Average Value, Min Value, Max Value, Min ABS Value, Max ABS Value and RMS Value.

• PI: If you click the button, PI can be modified.

• Use Time Period: Defines the time period. Performance Index is reported from Start to End time only.

• Add: Adds Performance Index in the form set in output type

• Insert: Inserts a Performance Index at the current cursor row.

• Delete: Deletes a Performance Index at the current cursor row.

• Expression: Set the PI name and select the defined expression. And then select the treatment.

• Scope: Set the PI name and the Scope name. And then select the treatment

• ProcessNet: ProcessNet type supports 2 types (General, Python) and calls the defined Function when simulating DOE.

  • Create Performance Index - ProcessNet

    At the end of each trial, the function within the set Project/DLL/Script is called.

    

    Figure 4.168 Performance index - ProcessNet Example

    The value set in modelDocument.SetAnalysisResponseResult(double val) within the called function is output as a PI value for every trial.
