process Station 2 Machine A Station 4 Machine A Station 1 Station 3 Station 4 Machine B Station 2 Machine B Station 4 Machine C A production process makes personal protection equipments and has 4 workstations (see the flowchart). The process starts the operations for a unit at station 1. At station 2, a unit needs to be processed at either Machine A or Machine B (the two machines perform the same operations). The unit is then processed at Station 3. After that, the unit needs to be processed at either Machine A, Machine B or Machine C in Station 4 (the machines perform the same operations), before it leaves the production site. Station 1: 5 minutes Station 2: Machine A, 34 minutes; Machine B, 34 minutes Station 3: 18 minutes Station 4: 60 minutes for each machine (as shown in the flowchart) Suppose that the input rate to the process is equal to the capacity of the whole process. What is the utilization of Machine Cat Station 4
