Question

4 pts Question 25 (This information applies to questions 21-25) Rocky Top hardware specializes in manufacturing steel bars. The process starts with raw material (carbon steel wire), then progresses sequentially through five steps using machines A to E, respectively (see diagram below). This is the only use that the five machines are put to. The hourly throughput rates (in Ibs/hour) for each machine are provided in the diagram below. Raw Material Step 1 A Step 2 B Step 3 C Step 4 D Step 5 E Market Demand THr=50 THr=90 THr=60 THr=100 THr=120 Going back to the initial throughput rates (i.e., as shown in the diagram), if market demand is 95 lbs/hour, the following resource is the constraint: Machine A Machine B Market Demand Machine C O Machine E

Answer 1

Answer 23: 30 lbs.

The market demand is 80 lbs and the current througput rate of the machine B is 50. So, additional throughput rate required to achieve the demand = 80 lbs - 50 lbs 30 lbs

Answer 24: B, A & C

The market demand is 95lbs / hour. So, the machine that has the lbs lesser than 95 lbs should be improved to improve the overall output of the system.

Answer 25: Machine B

The machine B is the constraint because of the machine B, the overall efficiency of the process surge down to 50 lbs. All the other machines in the further step has higher throughput rate compared to machine B. So, machine B is the constraint in the process.
