1.    What are Priority Rules   

                Priority rules provide guidelines for the sequence in which jobs should be worked.
        The rules generally involve the assumption that job setup cost and time is independent of
        processing times. In using this rules, job processing times and due dates are important pieces
        of information. Job times usually include setup and processing times. Due dates may be the
        result of delivery times promised to customers, MRP processing, or managerial decisions. The          rules are especially applicable for processs-focussed facilities such as clinics, print shop and
        manufacturing job shops. Priority Rules try to minimise completion time, number of jobs in the
        system, and job lateness, while maximising facility utilisation.

            Meeting due dates of customers or downstream operations.
            Minimising the flow time(the time a job spends in the process).
            Minimising work-in-process inventory.
            Minimising idle time of machines or workers.
