(a) The Workshop Manager must decide the sequence in which the four vehicles in the workshop must be serviced. He has developed these estimates based on the First-Come-First-Served sequence rule:

Vehicle ID Number Estimated Maintenance Time (days) Time to Promised Delivery (days) FCFS Order Sequence
226 27 39 1
229 33 30 2
224 41 60 3
225 29 75 4

Rank the FCFS, SPT and CR sequencing rules on three evaluation criteria: average flow time, average number of jobs in the system, and average job lateness.
