Standard Formulations

Sometimes it helps if a modeler has a toolbox with a number of standard formulations available for recurring problems so attacking new situations becomes just an incremental effort.

Reusing the standard inventory balance formulation helped simplify the model after which adding the extra complication of allowing next day delivery was easy.
