The average completion time (flow time) for the sequence developed using the FCFS rule = 11.75 days (round your
response to two decimal places).
The percentage utilization for the sequence developed using the FCFS rule = 42.55 % (enter your response as a
percentage rounded to two decimal places).
b) Using the SPT (shortest processing time) decision rule for sequencing the jobs, the order is (to resolve a tie, use the
order in which the jobs were received):
