The infeasible assignment can be avoided by assigning a very high cost to the cells where assignments are restricted or prohibited. Keep the rest of them the same. Step 9 — Find out the smallest number which does not have any line passing through it.

Step 2: In each row of the table find out the smallest cost element, subtract this smallest cost element from each element in that row. Definition of Assignment Problem 3. For each row or column with a single zero element cell that has not be assigned or eliminated, box that zero element as an assigned cell. Similarly, if the number of persons is less than number of jobs then we have introduce one or more dummy persons with zero duration to modify the unbalanced into balanced and then the problem is solved using the Hungarian Method.

This paper, based on some of Electrical Engineering concepts that can be considered equivalent to the concept of efficiency in data envelopment analysis, provides a new linear programming model to resolve assignment problems with multiple diverse inputs and outputs for each possible assignment.
If a no of lines drawn is equal to the no of or columns the current solution is the optimal solution, otherwise go to step 6. Now as the problem forms one to one basis or one job is to be assigned to one facility or machine. Choose the smallest of these elements and subtract this smallest from all the elements that do not have a line through them. Because we were able to make five assignments when six were required. We will discuss the transportation problem first.
