Question

Quizplus · Accepted Answer

The first two steps can process a total of 50 customers per hour, which is greater than the capacity of the third step. Therefore, if the first two steps are run at full capacity, there will be a waiting line for the third step. This means that the bottleneck of the system is the third step, not the first or second step. Therefore, option A and D are not true. Option B is not applicable because there is only one fixed bottleneck in the system.
