## Solve the Following Minimal Assignment Problem : - Mathematics and Statistics

Solve the following minimal assignment problem :

## Solution Show Solution

Step 1 : We introduce a dummy machine M 2 with time zero for each job and replace '-' by ∞

Step 2: Subtracting minimum element of each row from all its elememts

As minimum number of lines = 4 ≠ order of the matrix. . . Optimal solution is not reached. Step 3 : We subtract minimum element (from uncovered elements) from each uncovered element and add to intersection elements.

Minimum number of lines= 5 = order of matrix. :. Optimum solution is reached. Step 4 : Making assignment at single zero of the row and of the column.

. . The optimal assignment of jobs to machines is

M 1 → B M 2 → D M 3 → E M 4 → C M 5 → A
