Why is north west corner method used?
Why is north west corner method used?
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 variables are selected from the extreme left corner.
What are the steps to solve north west corner method?
Numerical
- Step 1: Balance the problem.
- Step 2: Start allocating from North-West corner cell.
- Step 3: Remove the row or column whose supply or demand is fulfilled and prepare a new matrix.
- Step 4: Repeat the procedure until all the allocations are over.
What is the transportation cost by NW corner method?
Here, NorthWest Corner Method will be used. And according to the NorthWest Corner Method this is the final initial basic feasible solution: Now, the total cost of transportation will be (200 * 3) + (50 * 1) + (250 * 6) + (100 * 5) + (250 * 3) + (150 * 2) = 3700.
Who invented north west corner rule?
The solution to this problem was first offered by George B. Dantzig and published in Koopman’s (1951) monograph 13. The procedure that Dantzig used to obtain an initial basic feasible solution was later termed the North-West Corner Rule by Charmes and Cooper (1954 to 1955). Dantzig’s initial solution ignored costs.
Which statement is true if north west corner method is used for solving?
So, the North West Corner method is used to compute the initial feasible solution. This method starts from the north west (i.e., upper left) cell. From the figure above, we can clearly see that 20 units are assigned to the first cell (i.e., upper left) that satisfies the demand of D. So, option A is the correct Answer.
What is north west corner rule Mcq?
Q83 – The northwest corner rule requires that we start allocating units to shipping routes in the: middle cell. Lower right corner of the table. Upper right corner of the table.
Which cell receives the first allocation in the north west corner rule?
Answer: the northwest corner method, an initial allocation is made to the cell in the upper left-hand corner of the tableau (i.e., the “northwest corner”). The amount allocated is the most possible, subject to the supply and demand constraints for that cell.
What is transportation problem in RMT?
The transportation problem is a special type of linear programming problem, where the objective is to minimize the cost of distributing a product from a number of sources to a number of destinations.
What do you mean by Modi method?
MODI method is an improvement over stepping stone method. This model studies the minimization of the cost of transporting a commodity from a number of sources to several destinations. The supply at each source and the demand at each destination are known.
Which statement is true north west corner method is used for solving?
Is northwest corner method the allocations are made?
Answer: With the northwest corner method, an initial allocation is made to the cell in the upper left-hand corner of the tableau (i.e., the “northwest corner”). The amount allocated is the most possible, subject to the supply and demand constraints for that cell.
What is transportation method?
Definition: The Transportation Method of linear programming is applied to the problems related to the study of the efficient transportation routes i.e. how efficiently the product from different sources of production is transported to the different destinations, such as the total transportation cost is minimum.
