J 100 Expected Learning Outcomes ⢠Basics of Transportation Models ⢠Different ways of developing initial solution to a Transportation problem â Northwest-corner and Least Cost Method If unbalanced, add dummy source (row) or dummy destination (column) as required. The lowest transportation cost among all the costs, is found in the cell-(3, 4), which is 5; the city requirement is 30 and plant-3 can supply at most 40. If this is for a transportation problem or similar note that an initial feasible basic solution obtained by a NWC corner rule has (almost) no resemblance with a final (optimal) basic solution. 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 ânorthwest cornerâ).

Transportation problem - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. The North-West corner cell is (1,1) and the supply and demand values corresponding to cell (1,1) are 250 and 200 respectively. For our better understanding of the method, we solve the same Adani Power limited problem which introduced and solved by North-west corner method. The solution displayed was obtained by performing some iterations of the transportation method on this problem. The North-West corner method gave transportation cost of â¦2,336,000, Least Cost (minimum) method gave transportation cost of â¦4,160,900 and Vogel Approximation method gave â¦2,331,800 as its transportation cost. From its inception, Olinâs only constant has been our drive to transform how engineering is taught, learned, and perceived. any given tractable balanced transportation problem.
