Question
Using the information presented in the following table, identify the processing sequence that would
result using (1) FCFS, (2) SPT, (3) EDD, and (4) CR. For each method, determine (1) average job
flow time, (2) average job tardiness, and (3) average number of jobs in the system. Jobs are listed
in order of arrival. (Hint: First determine the total job time for each job by computing the total processing time for the job and then adding in the setup time. All times and due dates are in hours.)
