Operations Research (Optimization) Calculators

These solvers are built for students and analysts who need to see the method, not just the answer. The transportation problem calculator finds a starting solution with Vogel’s approximation, north-west corner or least cost, then tests optimality with MODI. The Hungarian method solver handles minimisation, maximisation, unbalanced and restricted assignment problems.

For general models, the linear programming calculator shows simplex tableaus using two-phase, Big-M or dual simplex, and the integer programming calculator uses branch and bound with LP relaxation bounds and the optimality gap. Guides explain each method with worked examples, from the graphical method to the Gomory cutting plane.

The tools are checked against standard textbook problems. For large or production models, use a dedicated solver such as those covered in our Excel Solver and Python guides.
