The Atlantic Coast Conference (ACC) has four basketball games on a particular night. The conference office wants to assign four of five teams of officials (A, B, C, D, and E) to the four games in a way that will minimize the total distance traveled by the selected teams of 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 miles for each team of officials to each game location are shown in the following table:

	Game Sites
Officials	Raleigh	Atlanta	Durham	Clemson
A	210	90	180	160
B	100	70	130	200
C	175	105	140	170
D	80	65	105	120
E	125	85	110	180

Solve this problem as a network modeling problem. What is the optimal assignment of teams of officials to games? What are the total miles traveled for the teams of officials to reach all of the games? Define the decision variables. Develop an objective function. Develop constraints.
