The Palestinian ministry of sports has four basketball games on a particular night. The ministry wants to assign four teams of officials to the four games in a way that will minimize the total distance traveled by the officials. The supply is always one team of officials and the demand is for only one team of officials at each game. The distances in km for each team of officials to each game location are shown in the following table

officials 1 2 3

a 100 150 120

b 130 210 90

c 120 170 90

A) Formulate this problem as Assignment Model (the objective function and constraint equations for the demand and supply)

. b) Use QM to solve the Model.
