Consider a process with three machines in series: M1 with a processing (cycle) time of 5 min/unit, M2 with a processing time of 10 min/unit, and M3 with a processing time of 7 min/unit. A product goes through M1 first, then M2, and finally M3.The bottleneck is:

a) M2

b) None

c) M3

d) M1

Suppose that the process operates at the capacity of the bottleneck.Which machine is blocked?

a) M2

b) None

c) M3

d) M1

Suppose that the process operates at the capacity of the bottleneck.Which machine is starved?

a) M2

b) None

c) M3

d) M1
