Katta and Jay  presented the problem of allocating a set of indivisible objects to agents in a fair and efficient manner. Mathematical Model Let be the cost of assigning the ith resource to the jth task.

Zhang and Bard  studied a multi-period assignment problem that arises as part of a weekly planning problem at mail processing and distribution centres. The Assignment Problem Suppose we have n resources to which we want to assign to n tasks on a one-to-one basis. We define the cost matrix to be the n × n matrix An assignment is a set of n entry positions in the cost matrix, no two of which lie in the same row or column.

This step results in at least one zero in every row and column.

If there is a complete set of assignments with zero elements is possible than the resultant equivalent cost table is the optimal solution otherwise go to next step.

Assignment of jobs to workers, contract to contractors undergoing a bidding process, assigning nurses to duty post, or time tabling for teachers in school and many more have become a growing concern to both management and sector leaders alike.

Now if there is a complete set of assignments with zero elements is possible than the resultant equivalent cost table is the optimal solution otherwise repeat this step( step 3).

The total cost of the optimal solution is the sum of amounts that have been subtracted from each row of the cost matrix.

Hungarian Algorithm for Assignment Problem Set 1 Introduction Let there be n agents and n tasks. Any agent can be assigned to perform any task, incurring some cost that may vary depending on the agent-task assignment. It is required to perform all tasks by assigning exactly one agent to each task and exactly one task to each agent in such a way that the total cost of the assignment is.…

The assignment problem is a special case of the transportation problem, which in turn is a special case of the min-cost flow problem, so it can be solved using algorithms that solve the more general cases. Also, our problem is a special case of binary integer linear programming problem which is NP-hard. But, due to the specifics of the problem, there are more efficient algorithms to solve it.…

This problem is Kuhn’s Hungarian method Kuh55. This method is of major theoretical interest and is still used widely. It maintains a price for each object and an incomplete assignment of persons and objects. At each iteration, the method chooses an unassigned person and computes a shortest augmenting path from this person to the set of unassigned objects, using reduced costs as arc.…
