Definition- Vogel's Approximation method(VAM) or Penalty Method is a heuristic method which is used to calculate initial basic feasible solution(ibfs) to the transportation problem. It doesn't provide us the optimal solution. VAM is an improved version of Least-cost method. The ibfs obtained from Vogel's approximation method is better as compared to other methods. I am optimistic that following video will help you to solve VAM method easily.
Procedure of VAM:
Step 1- Calculate penalties for each row and column.
Penalty= 2nd Minimum-Minimum number
Step 2- Select maximum penalty and allocate as much as possible to the minimum cost for that penalty.
Step 3- In case of tie among the highest penalties, select row or column having minimum cost.
Step 4- In case of tie in the minimum cost also, select cell which can have maximum allocation.
Step 5- If there is tie in maximum allocation also, select the cell arbitrarily for allocation.
