- The M–N plant manufactures two different products: M and N. Selling prices and weeklymarket demands are shown in the following diagram. Each product uses raw materialswith costs as shown. The plant has three different machines: A, B, and C. Each performsdifferent tasks and can work on only one unit of material at a time.Process times for each task are shown in the diagram. Each machine is available2,400 minutes per week. There are no “Murphys” (major opportunities for the system tofoul up). Setup and transfer times are zero. Demand is constant.Operating expenses (including labor) total a constant $12,000 per week. Raw materialsare not included in weekly operating expenses.a. Where is the constraint in this plant?b. What product mix provides the highest proi t?c. What is the maximum weekly proi t this plant can earn?A firm is attempting to minimize its shipping costs.
