Transportation modeld are a common linear programming application. Algebraically portray the generalized structure for the LP formulation that would be appropriate to solve the general class of problem that is designed to move product from a set of sources (e.g. production facilities) to another set of destinations (e.g. distribution centers) at a total minimum cost. Be sure to fullh define all symbols for variables and/or parameters that you use in your portrayal. Finally, be sure to describe the story represented for each category of equation you present.
