In this chapter, we continued our discussion of linear programming models. The basic steps for formulating a linear program were followed for a variety of problems. These included applications in marketing, production scheduling, finance, and ingredient blending. Attention was paid to understanding the problem, identifying the objective and the constraints, defining the decision variables, and developing the mathematical model from these.

In future chapters, additional applications of linear programming will be presented. The transportation problem will be discussed in Chapter 9, along with two other closely related applications: the assignment problem and the transshipment problem.
