The MODI method, or Modified Distribution Method, is a technique used to find the optimal solution for transportation problems in operations research. It builds on an initial feasible solution, which can be obtained through methods like the Northwest Corner Rule. The MODI method involves calculating a set of values called "u" and "v," which represent the potential costs associated with each supply point and demand point, respectively.

The MODI method, or Modified Distribution Method, is an optimization technique used in transportation problems to find the least-cost solution by iteratively improving an initial feasible solution, adjusting allocations based on a calculation of opportunity costs, until no further cost reductions can be achieved.

The MODI method, or Modified Distribution Method, optimizes transportation problems by adjusting an initial feasible solution based on opportunity costs in the cost matrix. It reallocates resources from less cost-effective routes to more cost-effective ones to minimize overall transportation costs.
