  1. Total supply for motors.
SS= 780+770 +610 = 2,160 motors.
  1. Use LCM (Least cost method) to construct a transportation tableau.
Identify the least cost in the whole table.

Interpret the starting solution from the least cost method.
Total minimum cost:
(140*20) + (470*140) + (50*180) + (700 * 210) + (730* 280)+ (70*320)
= 451,400Euros.
Stat 279 Operations ResearchUsing the Least cost method to solve the transportation problem, it can be concluded that to obtain the minimum cost of transporting to Nanuq International, it will cost $ 451,400 and the supplies should originate from the suppliers in Europe as indicated by the tableau above. It will have to transport a total of 2,160 electric motors. 
  1. Obtain the optimal solution using excel. Cut and paste the excel output into word document and interpret the solution.
Conclusion:
  • 140 Electric motors should be transported from Rouen to Jung.
  • 70 Electric motors should be transported from Gaydon to Reynosa
  • 630 Electric motors should be transported from Rouen to Reynosa
  • 190 Electric motors should be transported from Gaydon to East Tamaki
  • 610 Electric motors should be transported from Dresden to East Tamaki.
Excel:
  1. According to excel, the total cost is 423, 500
Problem 2.
Calculate the total cost according to the excel solution. Also comment on any excess supply or demand.
According to excel solution, the Total minimum cost is $ 167,000
According to excel, the following persons should be assigned the following projects;
