One disadvantage of using North-West Corner rule to find initial solution to the transportation problem is that A) It is difficult to use. B) It does not take into account the cost of transportation. C) It leads to a degenerate initial solution. D) Transportation cost is maximum.
Hint- In order to solve the problem go through the rules of North-West Corner rule and then find the disadvantage accordingly.
Complete step-by-step solution: The north-west corner rule is a method adopted to compute the initial feasible solution of the transportation problem. The name north-west corner is given to this method because the basic variable is selected from the entrance left corner. In the case of transportation problem the north-west corner rule does not take into account the cost of transportation Hence, option B is the correct option.
Note- The north-west corner rule is easiest to solve transportation problems, students can come across the disadvantages of this rule only after solving some problem by this rule.
