Unbalanced assignment problem it is an assignment problem where the number of persons is no. Identify the minimum element in each row and subtract it from every element of that row. Here given problem is unbalanced and add 1 new column to convert it into a balance. The hungarian method gives us total assignment cost 870 along with the other three jobs assigned to dummy machine, in other words that these three jobs are ignored for further processing, while, when the original problem is divided in the sub-problems, which are balanced. An assignment problem can be easily solved by applying hungarian method which consists of two phases.

How did the Hungarian method get its name?

The most popular method available in literature for obtaining optimal policy of assignments is Hungarian method. It was published by Kuhn [1], who gave the name “Hungarian Method” because the algorithm was largely based on the earlier works of two Hungarian Mathematicians: D Kőnig and Egerváry.

How to solve the unbalanced matrix assignment problem?

Find the optimal assignment plan. Solution: As the given matrix is not balanced, add a dummy row D5 with zero cost values. Assign a high cost H for (M2, C) and (M4, A). While selecting the lowest cost element neglect the high cost assigned H, as shown in Table below.
