Station 2 Machine A 15 min/unit Station 4 Machine A 60 min/unit Station 1 6 min/unit Station 3 10 min/unit Station 4 Machine B 60 min/unit Station 2 Machine B 15 min/unit Station 4 Machine C 60 min/unit A manufacturing plant has four stations in the assembly line (illustrated in the image above). A unit needs to be processed at either Machine A or Machine B for Station 2 (parallel lines, both lines doing the exact same thing). The box is then processed at Station 3. After that, the unit needs to be processed at either Machine A, Machine B or Machine Cin Station 4 before leaving the production line. The process time of each station/machine is indicated in the flowchart. What is the process cycle time of this system measured in minutes? 91 minutes 6 minutes 20 minutes 226 minutes
