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 process time of each machine/station is indicated in
the flowchart. The unit is then processed at Stations 2 and 3 before leaving the work
cell. Specify the bottleneck(s).
