The North West corner rule is a technique for calculating an initial feasible solution for a transportation problem. In this method, we must select basic variables from the upper left cell, i.e., the North-west corner cell. North West Corner Rule Steps. Go through the steps given below to understand how to find a feasible solution for a ...
North-West Corner Method (NWC Rule) t is a simple and efficient method to obtain an initial basic feasible solution. Various steps of the. method are Step 1. Select the north-west (upper left hand) comer cell of the transportation table and allocate.
Nov 9, 2023 · An introduction to Transportation problem has been discussed in the previous article, in this article, finding the initial basic feasible solution using the NorthWest Corner Cell Method will be discussed. Explanation: Given three sources O1, O2 and O3 and four destinations D1, D2, D3 and D4.
Methods to Solve: To find the initial basic feasible solution there are three methods: NorthWest Corner Cell Method. Least Call Cell Method. Vogel’s Approximation Method (VAM). Basic structure of transportation problem:
At each step the simplex method attempts to send units along a route that is unused (non-basic) in the current BFS, while eliminating one of the routes that is currently being used (basic).
It is a standard method for computing a basic feasible solution (which will be denoted BFSNW in the following), and it does so by fixing the values of the basic variables one by one and starting from the Northwest corner of matrix C; see Figure 1 for a short description.
