The M–N plant manufactures two different products: M and N. Selling prices and weekly market demands are shown in the following diagram. Each product uses raw materials with costs as shown. The plant has three different machines: A, B, and C. Each performs different 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 available 2,400 minutes per week. There are no “Murphys” (major opportunities for the system to foul up). Setup and transfer times are zero. Demand is constant. Operating expenses (including labor) total a constant $12,000 per week. Raw materials are 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?

Question
The M–N plant manufactures two different products: M and N. Selling prices and weekly
market demands are shown in the following diagram. Each product uses raw materials
with costs as shown. The plant has three different machines: A, B, and C. Each performs
different 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 available
2,400 minutes per week. There are no “Murphys” (major opportunities for the system to
foul up). Setup and transfer times are zero. Demand is constant.
Operating expenses (including labor) total a constant $12,000 per week. Raw materials
are 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?
