Answer:
Station 1
Step-by-step explanation:
A bottleneck station is a point of congestion in a production system. It is the station that limits the capacity of the whole system. In an array of stations, the bottleneck station is the station with the lowest capacity.
For the case above, the capacity of each station is stated below;
Station 1 = 3 per hour
Station 2 = 5 per hour
Station 3 = 2+2 = 4 per hour
Station 4 = 4 per hour
Station 5 = 6 per hour
Therefore, the station with the lowest capacity is station 1, which is the bottleneck station for the system.
