Consider a production line with five stations. Station 1 can produce a unit in 9 minutes. Station 2 can produce a unit in 8 minutes. Station three has two identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines). Station 4 has two lines: one line has two continuous machines with a process time of 5 minutes/unit and 6 minutes/unit; the other line can produce a unit in 10 minutes. The bottleneck is station(just fill in a number in this question), the system process time ismin/unit, the cycle time ismins. If one week has 5 working days and each day operates 8 hours, then the weely capacity isunit/week.
