Northwest corner method

Please read them carefully. Since 30 units are available with the source A, the supply gets fully saturated. In case the demand is more than supply, then dummy origin is added to the table.

The supply of source B also gets fully saturated. The transportation costs in Rs. If the demand for the first cell is satisfied, then move horizontally to the next cell in the second column.

Now the total cost can be computed. Steps in North West Corner Rule Select the upper left-hand corner cell of the transportation table and allocate as many units as possible Northwest corner method to the minimum between available supply and demand, i.

North-West Corner Rule

Once the demand and supply are equal, the following procedure is followed: The North-West Corner Rule is a method adopted to compute the initial feasible solution of the transportation problem.

The Total cost can be computed by multiplying the units assigned to each cell with the concerned transportation cost. Continue the process until all supply and demand values are exhausted.

North West Corner Method

The basic variables are selected from the north-west corner of the transportation matrix. This trial routing method is often far from optimal. Every day the demand of three retailers D, E, F is to be furnished with at least 20 units, 95 units and 35 units of product respectively.

Now move vertically in the matrix and assign 40 units to Cell BE. In the table, three sources A, B and C with the production capacity of 50 units, 40 units, 60 units of product respectively is given.

Now move horizontally and assign 30 units to the cell AE. North West Corner Method North West corner method is used in transportation problems to calculate basic feasible solution. The standard instructions for a transportation model are paraphrased below.

North West Corner Rule The North West corner rule is a method for computing a basic feasible solution of a transportation problem, where the basic variables are selected from the North — West corner i. Move horizontally in the matrix and assign 35 units to cell CF, both the demand and supply of origin and destination gets saturated.

Minimum Transportation Cost Calculator Using North West Corner Method

The supply of dummy origin will be equal to the difference between the total supply and total demand. Such as 20 units are assigned to the first cell, that satisfies the demand of destination D while the supply is in surplus.

Select the north-west or extreme left corner of the matrix, assign as many units as possible to cell AD, within the supply and demand constraints. Again the cost associated with the dummy source will be zero. The concept of North-West Corner can be well understood through a transportation problem given below: Select the north west upper left hand corner of the transportation matrix and assign as many units as possible equal to the minimum between available supply and given demand Adjust the supply constraint and demand constraint in the respective rows and columns If the demand in the first cell is fulfilled, then we move horizontally to the next cell in the second column If the supply for the first row is over, then we need to move down to first cell in the next row For any cell, if the supply and demand equal, then the next allocation is made in a cell of the next row or column The process needs to be continued until all the supply and demand are exhausted Hence, this concludes the definition of North West Corner Method along with its overview.The North West corner rule is a method for computing a basic feasible solution of a transportation problem, where the basic variables are selected from the North – West corner (i.e., top left corner).

The standard instructions for a transportation model are paraphrased below. Please read them carefully. Minimum Transportation Cost Calculator Using North West Corner Method 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 because the basic variables are selected from the extreme left corner. Oct 26,  · Example of the Northwest Corner Method (Transportation Algorithm in Linear Programming).

Description step by step of Northwest Corner Method/5(18). Find an initial basic feasible solution of the given transportation problem using northwest corner rule. Solution. Starting from the North west corner, we allocate 20 units to F 1 W ultimedescente.com demand for the first column is completely satisfied.

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.
