LILIT 6. Challenging Question - Scheduling for Rescuing Scuba Divers (10 pts) Type: C Tom Cruise has worked as an operations manager of Underwater Treasure Discovery Company in San FL and recently he was assigned to make a schedule to dispatch deep water robots to save five scuba dveh needing urgent rescue out of danger under the deep sea. He must do a very brief assessment of how urgent each diver appears and need to determine the best sequence to save all five scuba divers. All the information he knows are dive-in time, remaining processing time to complete the assigned job, and dive time remaining scuba oxygen tank. Please do your best to save all five scuba divers with BEST OPTIMAL SEQUNECE using your knowledge of scheduling rules! We assume that the current time is 11:00 AM and the time to rescue divers will not be considered for scheduling since a rescue robot called "Diving bei can rescue a diver immediately regardless of location.)

WHY? (Part 1. -1pt] Please select an appropriate scheduling rule for this case among FCFS (First Come First Served), SPT (Shortest Processing Time), EDD (Earliest Due Date), LPT (Longest Processing Time), CR (Critical Ratio). [Part 2. - 1 pt) Explain the reason you've chosen that dispatching rule for this case.) (Part 3. - 2 pts] You should fill out (at least) ONE scheduling table for the scheduling rule/criteria you have chosen. (4 points) (b) In what sequence should the jobs be processed according to the scheduling rule you have determined in part (a) above? (2 points) c) With the job sequence you have determined in part (b) above, what is the average completion time of each job in the system? (2 points) (d) With the job sequence you have determined in part (b) above, what is the utilization for this case? (2 points)
