Which one of the following is riot the solution method of transportation method?

The matrix in assignment model is

In order for a transportation matrix which has six rows and four columns not to degenerate, what is the number of occupied cells, in the matrix?

Consider the following statements:
1. For the application of optimally test in case of transportation model, the number of allocations should be equal to (m + n) where m is the number of rows and n is the number of columns.
2. Transportation problem is a special case of a linear programming problem.
3. In case of assignment problem, the first step is to dummy row or a matrix by adding a dummy row or a dummy column.

Which of these statements is/are correct?

Consider the following statements on transportation problem:
1. In Vogel’s approximation method, priority allotment is made in the cell with the lowest cost.
2. The North-west corner method ensures faster optimal solution.
3. If the total demand is higher than the supply, transportation problem cannot be solved.
4. A feasible solution may not be an optimal solution.

Which of these statements are correct?

Penalty cost method is

One disadvantage of using North-West Corner Rule to find initial solution to the transportation problem is that
