Develop a schedule by using the first-come, first-served (FCFS) rule and calculate the average flow time and average days past due for the schedule.
Develop a schedule by using the earliest due date (EDD) rule and calculate the average flow time and average days past due for the schedule.
Comment on the performance of the FCFS and EDD rules relative to average flow time and average days past due.
A customer calls requesting that a service technician be sent to her residence immediately to fix her cable box. It is late in the evening, and service technicians cannot be sent out at this time. You see that she has an appointment for a service technician to be sent tomorrow, but she is becoming more upset because she thinks her need is urgent.
