Station 1 Machine A 20 min/unit Station 2 Station 3 Station 1 Machine B 12 min/unit 8 min/unit 20 min/unit A three station work cell is illustrated in the image above. A unit needs to be processed at either Machine A or Machine B for Station 1 (parallel lines, both lines doing the exact same thing). The unit is then processed at Stations 2 and 3 before leaving the work cell. The process time of each machine/station is indicated in the flowchart. What is the capacity rate of this system measured in units/min?
