## What is VAM method in transportation problem?

A method for finding a first feasible solution to a transportation problem. The procedure begins by finding the two lowest cost cells for each row and column in the transportation problem array.

### Why VAM method is best?

VAM is a better method than the method of Least Cost and North West Corner in searching for feasible baseline solutions early. Allocate as many variables as possible with the smallest unit cost in the selected row or column. Adjust the supply and demand, and remove the rows or columns that have been fulfilled.

**Which of the method is used in solving transportation problem?**

Usually, the initial basic feasible solution of any transportation problem is obtained by using well known methods such as North-West corner method (NWCM) or Least-Cost Method (LCM) or Vogel’s Approximation Method (VAM), and then finally the optimality of the given transportation problem is checked by MODI.

## What are penalties in VAM method?

In VAM approach, Penalties are determined by the difference of two minimum costs of each row and each column. The highest penalty indicates that among the two minimum cost, one is the lowest and another is too high.

### Which is the best method of transportation problem?

VAM is the best solution method but degeneracy is a major issue in transportation problem. In a standard transportation problem with m sources of supply and n demand , any feasible solution requires allocations in m + n – 1 independent cells.

**How do you do transportation problems?**

To solve a transportation problem, the following information must be given:

- m= The number of sources.
- n= The number of destinations.
- The total quantity available at each source.
- The total quantity required at each destination.
- The cost of transportation of one unit of the commodity from each source to each destination.

## Why is VAM method used?

This method is used to reduce the transportation costs by interpreting in a mathematical table the transportation costs from one place to another. The column represents the demand centres while the row represents the supply points.

### Why VAM is called penalty method?

Note: Vogel’s Approximation Method is also called as Penalty Method because the difference costs chosen are nothing but the penalties of not choosing the least cost routes.

**What is the VAM and Modi method for solving transportation problems?**

Total Supply = 250 + 300 + 400 = 950 Total Demand = 200 + 225 + 275 + 250 = 950 (Total Supply = Total Demand) Number of Occupied Cells = n + m – 1 = 3 + 4 – 1 = 6 Warehouses D1 D2 D3 D4 Capacit y (Supply) Pro duc tion Fac iliti es S1 11 12 17 14 250 S2 16 18 14 10 300 S3 21 24 13 11 400 Requireme nt (Demand) 200 225 275 250 950 10.
