A leatherworks factory has two punch presses for punching holes in the various leathergoods produced in the factory prior to sewing. Suppose that 12 different jobs must beprocessed on one or the other punch press (i.e., parallel processing). The processingtimes (in minutes) for these 12 jobs are given in the following table.Job 1 2 3 4 5 6 7 8 9 10 11 12Time 26 12 8 42 35 30 29 21 25 15 4 75Assume that both presses are initially idle. Compare the performance of SPT andLPT (longest processing time) rules for this example. (In parallel processing the nextjob is simply scheduled on the next available machine.)
