Mapping Model Parameters to Activity Parameters

You can use the Approximation adapter to map parameters defined by the approximation model to parameters defined by Optimization Process Composer. Mapping the parameters allows you to provide input to the approximation model and to access the output from the approximation model.

About the Approximation Adapter
  1. From the Utilities section of the action bar, click Approximation and drop it on the process diagram.
  2. Double-click Approximation .
    The Approximation Editor opens.
  3. Select the Category in which the approximation model will be stored.

    The default category is Internal Data.

  4. From the Content list, select an approximation model or do one of the following:
    • Search for and select an approximation model to add as referenced content.
    • Add a non-versioned document containing a file version of the approximation model.
    • Add a versioned document containing a file version of the approximation model.

    Note: The file version of an approximation model can be a coefficients file (.txt ) or an FMU file (.fmu ). See Approximations in the Results Analytics User Guide for more information.

  5. Click Load model.
    The model name and the model type appear in the editor. The model parameters appear in the Parameters table along with their mode (input or output).
  6. Click on a cell of the Activity Parameters column, and do either of the following from the menu that appears:
    • Accept the default name of the activity parameter (derived from the model parameter name).
    • Select the blank string to remove the mapping from the model parameter.

    You can map a model parameter only to a real activity parameter.

  7. Click the Model Configuration tab to view the approximation's interface definition—a description of its input and output model parameters.
  8. Click Ok to save your changes and to close the Approximation Editor.
