 Pyomo.DoE Required Inputs
 --------------------------------
-The required input to the Pyomo.DoE solver is an ``Experiment`` object. The experiment object must have a ``get_labeled_model`` function which returns a Pyomo model with four ``Suffix`` components identifying the parts of the model used in MBDoE analysis. This is in line with the convention used in the parameter estimation tool, `Parmest <https://pyomo.readthedocs.io/en/stable/contributed_packages/parmest/index.html>`_. The four ``Suffix`` components are:
