Consider the cost of assigning a task to an individual as shown
in the table below. It is assumed that each individual can be
assigned to at most one task, and each task can be assigned to at
most one individual. The objective is to minimize the cost of
assignments.
| individual | |||
| Task | 1 | 2 | 3 |
| 1 | 17 | 18 | 16 |
| 2 | 14 | 19 | 17 |
| 3 | 15 | 19 | 18 |
(a) Write down the linear programming formulation of this problem.
(i.e., write down the objective function and constraints – do not
use a tableau.)
(b) Using the Hungarian Algorithm, solve this assignment problem (i.e., the problem described on the previous page). Please show the order in which the tableaus are used!
(c) State the optimal values of the variables and the optimal objective function.
