However, we allow preemptions (i.e., we can interrupt a job and process it on different machines on different days). The scheduling problem is to determine a feasible schedule that completes all jobs before their due dates or to show that no such schedule exists. Formulate this problem as a maximum flow problem. ted). We assume that a machine can work on only one job at a time and that each job 2 A set J of Jobs are to be scheduled on M identical machines.
