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. where would you place a buffer?
