The rank order of the jobs by slack value (smallest to largest) makes sure that the jobs with too little slack time are performed first. This priority rule addresses the sequencing of jobs based on the value of work remainaining. 1B:1181109=1。 2B:1161102=4。 3B:1191106=3 sl a c k ti m e 39。 si n r e m a ini ng tim edue date today s date proc e s g? ? ?

The rank order of the jobs by ratio makes sure that the jobs with insufficient operations slack are performed first. 1B:1/4=1/4。 2B:4/1=4。 3B:3/3=1 slack per operation (S/O) = slack time / operations remaining ComputerIntegrated Manufacturing priority Oder number slack per operation 1 1B 2 3B 3 2B 8 Solution f: The rule identifies the job that is most behind schedule (the one with the lowest ratio) and the job most ahead of schedule (the one with the highest ratio).
