(a) Consider the following process flow diagram. Tasks A, B and C are such that they can be performed in the order A-B-C or C-B-A with the same outcome. sub-system "ab" 12 18 min/load min/load sub-system "a" 10 min/load A B C D B A 10 min/load 10 18 12 min/load min/load min/load sub-system "b" (i) Which task is the bottleneck of sub-system "a"? (ii) Which task is the bottleneck of sub-system "b"? (iii) What is the steady-state system capacity of sub-system "ab"? (iv) Which task is the bottleneck of the entire system? (v) What is the steady-state capacity of the entire system? (vi) If subsystems "a" and "b" are run at equal rates, what is the steady-state utilization of each of the individual Task C stations?
