LINEAR PROGRAMMING MODELS IN OPERATIONS MANAGEMENT

Linear programming (LP) is one of the most powerful analytic tools available to improve operations management. LP provides the optimal, or best possible, solution to problems that can be formulated by a linear function subject to a set of linear constraints. This has proven extremely useful in many operations management applications, some of which are described in Table 1.
