WBM Car Company produces four different models: M1, M2, M3 and M4. The Kanata plant produces the M1, M2 and M4 models. The M1 and M2 models are produced in Brenton. The Laval plant manufactures the M3 and M4 models. The capacities of the three plants and the demands of the distribution centers are given according to type of model.

MODEL

	M1	M2	M3	M4
Plant
Kanata	800	400	----	----
Brenton	500	600	----	400
Laval	---	---	700	300
Distribution Center
Trento	700	500	500	600
Bari	600	500	200	100

The transportation fee is the same for each model and is $1 10 cents per kilometer per car. The distance between the plants and the distribution centers is Kanata – Trento: 600 km; Kanata-Bari: 300 km; Brenton-Trento: 400 km; Brenton-Bari 400 km; Laval – Trento: 800 km; Laval – Bari: 150 km. WBM wants to determine the shipping plan for each model. PROVIDE FULLY DETAILED ANSWERS FOR THE 3 QUESTIONS, and help me with the third question, I really don't know what I can do without calculator and computer.

1. Formulate the WMB shipping problem as a single model and solve it. (use Lingo and attach the value output as well)

2. Draw a network representation of the WMB sending problem.

3. Formulate the WMB submission problem in such a way that someone who has never taken SCOM 361 or a similar course can easily solve it with pen and paper. Explain how a solution can be obtained without using a computer or calculator.
