A production line at V. J. Sugumaran's machine shop has three stations. The first station can process a unit in 9 minutes. The second station has three identical machines, each of which can process a unit in 15 minutes (each unit only needs to be processed on one of the three machines). The third station can process a unit in 7 minutes. Which station is the bottleneck station?

Station 1 is a bottleneck station because the processing time taken to process the product in such station is 9 minute when compared with Station 2 and Station 3

Explanation:

Station 1 = Processing time is 9 minutes

Station 2 = Processing time is 5 minutes per unit (15 minutes / 3  machines)

Station 3 = Processing time is 7 minutes

Thus, the Station 1 is the bottleneck station with a bottleneck time of 9 minutes per unit.
