To solve the transportation problem using the Northwest Corner Method (NWCM) and Least Cost Method (LCM), we first need to set up the initial transportation table with the given sources and destinations:
Let's assume the supply values for the sources are as follows: S1: 50 units S2: 70 units S3: 80 units
And the demand values for the destinations are: D1: 30 units D2: 40 units D3: 50 units D4: 60 units
Using the Northwest Corner Method, we start allocating units from the top left corner (S1, D1) until either the supply or demand for that row or column is exhausted. Then we move to the next row or column and repeat the process.
After applying the NWCM, we get the following initial solution:
Next, we can use the Least Cost Method to optimize the solution further. By calculating the costs for each cell and allocating units based on the least cost, we can arrive at an improved solution.
After applying the LCM, we get the following optimized solution:
To carry out a stepping stone method of post-optimality analysis, we need to identify the empty cells (non-basic variables) and calculate the improvement in cost for each potential move. By iterating through the empty cells and calculating the improvement in cost, we can determine the optimal solution.
By following the stepping stone method, we can continue to iterate and make improvements to the solution until we reach the optimum transportation plan.
