Answer question 8 parts a and b.
Distribution and Network models:
8. Forbelt Corporation has a one year contract to supply motors for all refrigerators produced by the Ice Age
Corporation. Ice Age manufactures the refrigerators at four locations around the country: Boston, Dallas, Los
Angeles, and St. Paul. Plans call for the following number (in thousands) of refrigerators to be produced at
each location:
Boston: 50
Dallas: 70
Los Angeles: 60
St. Paul: 80
Forbelt’s three plants are capable of producing the motors. The plants and production capacities (in
thousands) are as follows:
Denver: 100
Atlanta: 100
Chicago: 150
Because of varying production and transportation costs, the profit that Forbelt earns on each lot of 1000
units depends on which plant produced the lot and which destination it was shipped to. The following table
gives the accounting department estimates of the profit per unit (shipments will be made in lots of 1000
units):
Shipped To
Produced at: Boston Dallas Los Angeles St.
Paul
Denver 7 11 8
13
Atlanta 20 17 12
10
Chicago 8 18 13
16
With profit maximization as a criterion, Forbelt’s management wants to determine how many motors should be
produced at each plant and how many motors should be shipped from each plant to each destination.
