Simplex Method for Minimization LP Problems | Big-M Method Explained with Examples

In this lesson, we focus deeply on the Big-M Method in Linear Programming, one of the most powerful and widely used techniques for solving minimization problems involving greater-than (≥) and equality (=) constraints. This video is designed to help students clearly understand how artificial variables are introduced and how the Big-M approach ensures that they are eliminated to reach the optimal solution. We begin by explaining the intuition behind the Big-M Method in a very simple way. You will learn why artificial variables are needed and how a very large penalty value (M) is added to the objective function to force these variables out of the final solution. This conceptual understanding is extremely important for exams and practical applications. The lesson then walks you through the step-by-step procedure of the Big-M Method, including converting inequalities into equations, adding surplus and artificial variables, forming the modified objective function, and setting up the initial simplex tableau. Each step is explained clearly so you can follow the logic without confusion. We also solve detailed numerical examples using the Big-M Method, showing how to perform iterations, select entering and leaving variables, and interpret the final optimal solution. Special attention is given to common mistakes students make and how to avoid them during exams. Finally, we briefly compare the Big-M Method with the Two-Phase (Conversion) Method to help you understand when and why Big-M is preferred in many cases. By the end of this video, you will be confident in solving Linear Programming problems using the Big-M Method from start to finish.
