Introduction to Linear Programming. Linear Programming Problem. Problem Formulation. A Simple Maximization Problem. An optimization problem is a problem in which we wish to determine the best values for decision variables that will maximize or minimize a performance measure subject to a set of constraints. A feasible solution is set of values for the decision variables which satisfy all of the constraints. We could use an application of linear inequality systems.. Ex. Jenny’s Bakery makes two types of birthday cakes: yellow cakes which sell for $25 and strawberry cakes which sell for $35. Both cakes are the same size, but the decorating and assembly time required for the yellow cake is 2 hours, while the strawberry cake takes 3 hours. There are 450 hours of labor available for production. How many of each type should be made to maximize revenue?. Optimization problems where design variables have to be integers are more difficult than ones with continuous variables.. The degree of difficulty is particularly damaging for large number of variables:. Saba . Neyshabouri. Operations Research. OR was developed and used during world war II.
