A production department of a textile firm received six different orders this week. They have calculated the processing time presented as a table (below). They have also put the due dates for each job. Job A C E B D F Process. Due Time: 2 4 5 8 10 12 Date 7 4 15 16 17 18 Based on the table please provide four sequences to complete the jobs: a) Using first come first served (FCFS) assuming the letters represent the order they arrive (A first, B next, then C, etc..) b) Using shortest processing time c) Using longest processing time d) Using due dates Calculate "average completion time","average number of jobs in the system" and "average job lateness" for all the sequences you have generated above.
