Question

Ryan Electronics has production facilities in Denver and Atlanta, warehouses in Kansas City and Louisville, and retail outlets in Detroit, Miami, and Dallas. Each production facility can deliver to each warehouse and each warehouse can deliver to each retail outlet. The shipping costs per unit appear in the table below:

From	To	Cost ($/unit)
Denver	Kansas City	4
Denver	Louisville	3
Atlanta	Kansas City	2
Atlanta	Louisville	1
Kansas City	Detroit	2
Kansas City	Miami	3
Kansas City	Dallas	4
Louisville	Detroit	5
Louisville	Miami	4
Louisville	Dallas	6

Production is 600 units at the Denver plant and 250 units at the Atlanta plant. Demand is 250 units at the Detroit outlet, 200 units at the Miami outlet, and 400 units at the Dallas outlet.

1. Formulate a linear program (variables, objective, and constraints) to minimize cost while moving supply from the production plants through the warehouses to the retail outlets.
2. Is this problem a Transportation, Assignment, or Transshipment Model? Explain you answer in a few short sentences.
