Question
A steel product is manufactured by starting with raw material (carbon steel wire) and then processing it sequentially through five operations using machines A to E, respectively (see table below). This is the only use that the five machines are put to. The hourly rates for each machine are given in the table. Answer the following questions. Use the original output rates to answer each question (i.e., disregard any changes mentioned in previous questions).
By how much would the output be improved if B was increased to 110?
By how much would the output be improved if C was increased to 50?
By how much would the output be improved if C was increased to 60?
What is the effect on the system if machine A can only manage an output of 30 in one hour?
What is the effect on the system if machine C can only manage an output of 10 in one hour?
What is the effect on the system if machine B is allowed to drop to an output of 30 in one hour?

Explanation / Answer
Maximum output per hour is 30 units because C is the bottleneck with least cycle time. 0 products. Because there will be inventory accumulation before C, but C will still produce 30 units per hour. By 10 units, because now A becomes bottle neck and the line will produce 40 units per hour. By 10 units, because still now A is the bottle neck and the line will produce 40 units per hour. We lose 0 products, because the Maximum the line can produce is still 30 units per hour We lose 20 units, because the bottle neck is still C with 10 units per hour. We lose 0 products, because the Maximum the line can produce is still 30 units per hour
