Station 1 5 min/box Station 2 Machine A 15 min/box Station 3 10 min/box Station 4 10 min/box Station 2 Machine B 15 min/box A process is depicted in the picture. After being processed in the first station, a box needs to be processed at either Machine A or Machine B for the parallel line. The box is then processed at Stations 3 and 4 before leaving the production line. The process time of each station/machine is indicated in the flowchart (e.g., 5 min/box means that the process time is 5 minutes to process each box at the machine/station). What is the process cycle time of this system measured in minutes?
