(Ch. 11 Q. 9) Consider a three sequentially stepped process named as Process A, Process B and Process C. Input comes into Process A. Output form A goes into Process B. Output from B goes into Process C. Output of C is the final output. Suppose that it takes 2 minutes per unit in Process A, 3 minutes per unit in Process B and 1 minute per unit in Process C. Suppose further that Process A receives input at the rate of 30 per hour. Which process will be experiencing starving?

Process C

categorizes the potential causes of a problem in order to identify its root causes

(Ch. 11 Q. 8) Consider a three sequentially stepped process named as Process A, Process B and Process C. Input comes into Process A. Output form A goes into Process B. Output from B goes into Process C. Output of C is the final output. Suppose that it takes 2 minutes per unit in Process A, 3 minutes per unit in Process B and 1 minute per unit in Process C.

What will be maximum steady state output from this system?

20 per hour
