In Operations Research, solving a transportation problem involves determining the most cost-effective way to transport goods from multiple sources to multiple destinations while satisfying the supply and demand constraints. The process begins with finding an initial basic feasible solution (IBFS), which serves as a starting point for optimization techniques such as the stepping-stone method or the MODI (Modified Distribution) method. Various methods are used to find this IBFS, including the North-West Corner Rule, Least Cost Method, and Vogel’s Approximation Method. Each of these methods has its own advantages and disadvantages, which make them suitable for different types of transportation problems.
