Logical binary constraints – Part 2 Suppose a company has 5 projects available to choose from. We define decision variables as follows: xi=1 if project i is selected, and 0…

Welcome to an Introduction to Linear programming. Let’s begin by looking at an example. Consider a company that manufactures and sells two camping lights. They sell one light with disposable…

Welcome! In this tutorial, we will solve this maximization problem using graphical method. Let’s label the constraints C1 to C4 for reference purposes. Let’s start by setting up tables to…

Welcome to this tutorial as we discuss special cases encountered while solving some linear programming problems. The special cases we’ll discuss include Alternative optimal solutions Infeasibility Unboundedness, and Redundancy. Let’s…

Welcome! In this tutorial, we calculate slack and surplus variables, identify binding constraints, and write the linear programming model in standard form. Let’s begin with this LP model. Here is…

Welcome! In this tutorial, we will graphically solve this minimization problem using the Objective Function Line Approach. Note that the use of the graphical approach is limited to 2 decision…

welcome in this tutorial are formulate linear integer programming models involving binary or 0 1 variables binary variables are employed when there is a yes or no situation that is…
