Answer #1

Answer: Option (B) - Johnson’s Rule

Explanation: In operations management, there are scenarios where jobs have to be scheduled in two work centers. In order to ensure that the jobs are optimally sequenced such that it reduces the total time to complete all the jobs (known as the makespan time), Johnson’s Rule is used. The Johnson’s rule minimizes the makespan time for a set of jobs that must be processed through a two-step system where every job follows the same sequence through the two processes.

Consider the problem of scheduling n jobs on a 3D printer. The turnaround time for a job is the total time from when it arrives to when it finishes printing. Suppose that all jobs arrive at the same time and that we know the time that job i will take time tᵢ to print once started on the printer. Prove that scheduling the jobs in greedy order (i.e. shortest job first) minimizes the average turnaround time.

In Exercise 2.3, we saw that SRPT does not minimize mean slowdown.
