To quickly obtain an initial feasible solution by starting with the top-left corner of the transportation tableau and allocating shipments based on the available capacities of supply and demand.

The North-West Corner Rule is a heuristic method used to initialize and find an initial basic feasible solution for transportation problems within the context of linear programming. Transportation problems involve optimizing the distribution of goods from multiple suppliers to multiple consumers while minimizing transportation costs. The main objective of using the North-West Corner Rule is to provide an initial solution that can serve as a starting point for more refined optimization techniques.

The Main Objective  of using North-West Corner Rule in transportation models is  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.
