Final answer:
The bottleneck station is the second station with a processing time of 16 minutes per unit, as each unit only goes through one machine, despite it having two identical machines.
Step-by-step explanation:
To identify the bottleneck station in V. J. Sugumaran's machine shop, we need to determine which station has the longest processing time per unit. Although the second station has two machines, each unit only goes through one, so we consider the time for one machine. The processing times for each station are as follows:
The second station is the bottleneck because it has the longest processing time of 16 minutes per unit, regardless of having two machines, as each unit is processed by only one machine.
