A

Summary Introduction

Interpretation:The best linear equations that show evidence of the objective functions and constraints in the given situation should be determined.

Concept Introduction: While the plant manager has the option to use two different routes; the route 1 uses Extruder A and the route 2 uses B extruder. The process of melting is used for both the routings.

B

Summary Introduction

Interpretation: A graphical solution based on the give data and formulated linear equations should be provided.

Concept Introduction: While the plant manager has the option to use two different routes; the route 1 uses Extruder A and the route 2 uses B extruder. The process of melting is used for both the routings.

C

Summary Introduction

Interpretation:The maximum profit that can be obtained from the given data is to be determined.

Concept Introduction: While the plant manager has the option to use two different routes; the route 1 uses Extruder A and the route 2 uses B extruder. The process of melting is used for both the routings.

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. D Demand Forecast Component A B C Time Standard Processing Setup (hr/unit) (hr/lot) 0.04 1.0 0.20 4.4 0.05 8.5 Lot Size (units/lot) 50 75 100 Demand Forecast Pessimistic Expected Optimistic Pessimistic 16,000 10,000 18,000 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…

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 30 percent capacity cushion is best.
