Overview

If your model is written in Pyomo, you create a Python module with the following functions. The remaining chapters in this section describe each one in detail.

• scenario_creator – builds a Pyomo model for one scenario (see scenario_creator function)

• scenario_names_creator – returns the list of scenario names (see Helper Functions in the Model File)

• kw_creator – returns keyword arguments for the scenario creator (see Helper Functions in the Model File)

• inparser_adder – adds problem-specific command-line arguments (see Helper Functions in the Model File)

• scenario_denouement – called at termination (can be None; see Helper Functions in the Model File)

Once you have these functions, you can use generic_cylinders.py (see generic_cylinders.py) to solve your problem using the EF or the hub-and-spoke system. See the farmer directory in examples for a complete working example (farmer.py and farmer_generic.bash).

For models written in an algebraic modeling language other than Pyomo (e.g., AMPL or GAMS), see AML Agnosticism. For models supplied as SMPS-format files, see SMPS Format Support.
