The manager of an automobile assembly plant must make decisions about the production schedule for her two types of car models next month. Several factors need to be considered, including a limited number of labor-hours, different numbers of labor-hours needed for each of the two car models, a limited number of car doors available from the door supplier, and a limited demand for one of the car models. When considering such options as targeted advertising and using overtime labor, the manager wishes to determine which plan will maximize the company’s profit.
