Question

In a transportation problem North-West corner rule would yield :

• A. An optimum solution
• B. An initial feasible solution
• C. A Vogel's approximate solution
• D. A minimum cost solution

Answer 1

Answer:

B. An initial feasible solution

North-West corner rule is a method to obtain an initial feasible solution in a transportation problem. Feasible solution is a set of non-negative individual allocation satisfying solution constraints. Basic feasible solution is when the total allocation is exactly (m+n-1). Other methods of basic feasible solution are Row-minima, Column-minima, Least cost and Vogal's approximation method. MODI method is used to find optimal solution. Stepping stone and MODI methods are used for optimality test.
