The function further enables the incorporation of intermediate commodities, in addition to primary and processed commodities, to account for the effects of reconstitution technologies on said forecasted values. The method generally comprises creating an inputs database comprising a definition of the regions and forecast scenarios, and a plurality of dairy sector data spanning a number of recent years including commodity prices and amounts of consumption, production and trade flow in the regions; refining the function; solving the refined function by maximizing a consumer and a producer surplus net of all transaction costs, to generate the forecasts; and, outputting the forecasts to a results database. The method may further solve for an optimal amount of intermediate commodities consumed in the making of the final processed commodities by region under an assumption of optimal use to further refine the forecasts. The system outputs in the forms of graphs, spreadsheets, maps, or other formats can be delivered electronically through various media.
