Homework: Chapter 4 - Problem Set Question 2, Problem 7 Part 1 of 4 HW Score: 33.33%, 10 of 30 points O Points: 0 of 10 Save Macon Controls produces three different types of control units used to protect industrial equipment from overheating. Each of these units must be processed by a machine that Macon considers to be their process bottleneck. The plant operates on two 8-hour shifts, 5 days per week, 52 weeks per year. The table below provides the time standards at the bottleneck, lot sizes, and demand forecasts for the three units. Because of demand uncertainties, the operations manager obtained three demand forecasts (pessimistic, expected, and optimistic). The manager believes that a 25 percent capacity cushion is best. Demand Forecast Setup Component Pessimistic Expected Optimistic Time Standard Processing (hr/unit) (hr/lot) 0.04 1.0 0.30 4.9 0.05 8.5 Lot Size (units/lot) 40 75 100 B 14,000 11,000 18,000 17,000 13,000 23,000 26,000 18,000 37,000 a. How many machines are required to meet minimum (Pessimistic) demand, expected demand, and maximum (Optimistic) demand? (Enter your responses rounded up to the next whole number.)
