Sensitivity analysis in transportation problem. (Oct 2006)
Sensitivity analysis in transportation problem can be done with the help of delta (opportunity costs) for empty cells. Delta indicates the change in cost per unit (increase or decrease) if that cell is included in the solution.
Hence, if in an optimal solution, delta for an empty cell is +4 & the unit transportation cost for that cell is 10. Then it means a reduction of at least 4 Rs. is required in the cost if that cell is to enter the solution. Hence, the new cost will be. 10 – 4 = Rs. 6.
