A production line at XYZ Inc. has five stations. Station one can process a unit in 15 minutes. The unit then flows to Station two, which can process a unit in 18 minutes. The third station can process a unit in 12 minutes. (This station operates separately from, and simultaneously with stations one and two, which are independent and sequential operations). Next, the unit from Station 2 and Station 3 flow to Station 4. Station 4 can process a unit in 17 minutes. The fifth station has three identical machines, each of which can process a unit in 30 minutes (each unit only needs to be processed on one of the three machines). a. The bottleneck of the process is with an hourly capacity of b. If XYZ Inc. added a second identical machine at Station 2 , what is the new bottleneck and capacity of the system c. What is the throughput time for XYZ Inc. to make 1 unit
