Consider the following four-workstation production line. Station Number of Machines Processing Time (hours) 1 1 0.05 2 6 0.25 3 3 0.2 4 2 0.167 1) (15 pts) What are the bottleneck rate, raw process time and critical inventory of this production line? 2) (15 pts) Assume that the current inventory level in this production line is 42 parts. What is the flow rate under the practical worst case? If the actual flow rate of this line is 10 jobs per hour, is the line running efficiently or not? 3) (15 pts) If we add an identical machine to Station 4 and keep the same number of inventory as in (b), i.e., 42, what is the flow rate under the practical worst case? If after adding this identical machine, the actual flow rate of the line increases to 14 jobs per hour, is the line running efficiently now? 4) (15 pts) Again, assume that the current inventory level in this production line is 42 parts. If we speed up both machines in Station 4 from each processing 6 jobs per hour to each processing 8 jobs per hour and keep the same number of inventory, what is the flow time under the practical worst case? If the actual flow time that we observed from the production line is 4 hours, is the line running efficiently now?
