3 | Shortest remaining processing time (SRPT) | Sorted by the remaining processing time of the job on all machines from shortest to longest |
4 | Most operations remaining (MOR) | Sorted by the number of the remaining operations on all machines from shortest to longest |
5 | Earliest due date (EDD) | Sorted by the due date from shortest to longest |
6 | Apparent tardiness cost (ATC) | Sorted by the tardiness cost from shortest to longest |
7 | Total least operations remaining (TLOPR) | Sorted by assembly-related constraints of the job from shortest to longest |
8 | Select no job (SNJ) | Machines don’t select processing each job |
