Unbalanced Assignment Problem. If number of rows is not equal to number of columns then it is called Unbalanced Assignment Problem. So to solve this problem, we have to add dummy rows or columns with cost 0, to make it a square matrix . Here given problem is unbalanced and add 1 new column to convert it into a balance.
How do you solve an unbalanced maximization assignment problem?
Unbalanced Maximization Assignment problem example. Solution: Convert the 4 × 5 matrix into a square matrix by adding a dummy row D5 . Column-wise reduction is not necessary since all columns contain a single zero. Now, draw minimum number of lines to cover all the zeros, as shown in Table.
How do you solve an assignment problem?
Although assignment problem can be solved either by using the techniques of Linear Programming or by the transportation method yet the assignment method developed by D. Konig, a Hungarian mathematician known as the Hungarian method of assignment problem is much faster and efficient.
How do you solve prohibited assignment problems?
This can be achieved by assigning a very high cost (say ∞ or M)to the cells where assignments are prohibited, thereby restricting the entry of this pair of job-machine or resource-activity into the final solution. Example : Five jobs are to be assigned to five men.
How unbalanced assignment problem is solved by Hungarian method?
When Hungarian method is applied to solve unbalanced assignment problem in which the numbers of jobs are more than the number of machines, the procedure assigns some of the jobs to dummy machines which actually ignore the execution of those jobs .
What is the assignment method?
What Is the Assignment Method? The assignment method is a way of allocating organizational resources in which each resource is assigned to a particular task . The resource could be monetary, personnel, or technological.
What are unbalanced assignment problems?
Unbalanced Assignment problem is an assignment problem where the number of facilities is not equal to the number of jobs . To make unbalanced assignment problem, a balanced one, a dummy facility(s) or a dummy job(s) (as the case may be) is introduced with zero cost or time.
What is impossible assignment?
It means we have the flexibility of assigning different allocations while still maintaining Minimum (Optimal) cost or Maximum (Optimal) profit. We can detect multiple optimal solutions when there are multiple zeroes in any columns or rows in the final (Optimal) table in the Assignment problem.
What is maximization assignment problem?
There may be situation when the assignment problem calls for maximization of profit. Such problem can be solved by converting the given maximization problem
Why dummy is added in assignment problem?
The purpose of a dummy row or column in an assignment problem is to obtain balance between total activities & total resources . Dummy rows (or columns) are added in the matrix so as to complete it to form a square matrix. The dummy rows or columns will contain all costs elements as zeroes.
Which method gives optimal solution to assignment problems?
In Section 3, a new method, namely ATOC method is proposed by an Algorithm to find the optimal solution of an assignment problem, followed by a Numerical Example. Variations of the Assignment problem are discussed Page 2 R.

What are the disadvantages of assignment method?
There are some demerits and limitations in this assignment method for both teachers and students. For the Teachers: It is time consuming and burden process. Teacher has to collect the information from various sources before assigning the work to the students. Work burden extends in holidays too.
