How to fill out the Big M Method Online online
The Big M Method Online is a powerful tool for solving linear programming problems. This guide will provide you with a clear framework to fill out the form correctly, with step-by-step instructions tailored to users at all experience levels.
Follow the steps to fill out the Big M Method Online form effectively.
- Press the ‘Get Form’ button to obtain the form and access it in your preferred online editor.
- Start with modifying the constraints to ensure that the right-hand side (RHS) of each constraint is nonnegative. Multiply any constraint with a negative RHS by -1, remembering to reverse the direction of the inequality.
- Convert each inequality constraint to standard form. For '<' constraints, add a slack variable. For '>' constraints, subtract an excess variable.
- Add artificial variables for any '>' or '=' constraints and ensure these variables have the restriction of being greater than zero.
- If the linear programming (LP) problem is a maximization one, incorporate '-M * ai' in the objective function. If it is a minimization problem, add 'M * ai' to the objective function.
- Solve the transformed problem using the simplex algorithm. Ensure artificial variables are eliminated from the pivot row before beginning the simplex method.
- At the conclusion, check if all artificial variables equal zero in the optimal solution to confirm a feasible solution exists. Otherwise, the original problem may be infeasible.
- Save your changes to the form. Depending on your needs, you can download, print, or share the completed form.

To identify the key column in the Big M method, look for the column with the most negative value in the objective function row during each iteration. This column represents the variable that will enter the basis to improve the current solution. Choosing the right key column is crucial for optimizing the process efficiently. This step is essential in ensuring an effective movement toward the optimal solution.
