1. Scheduling involves the timing of operations to achieve the efficient movement of units through a system. The overall objective of scheduling is faster movement of goods and services through a facility, better customer service and dependable delivery.

2. The four criteria for determining the effectiveness of a scheduling decision are
Minimize completion time
Maximize utilization
Minimize work in process
Minimize customer waiting time

3. Loading means the assignment of jobs to work or procession centers. Operations managers assign jobs to work centers so that costs, idle time, or completion times are kept to a minimum. Loading work centers takes two forms. One is oriented to capacity; the second is related to assignment specific jobs to work centers. The two techniques used to loading jobs are: Gannt charts and the assignment method of linear programming.

The four priority sequencing rules are:
FCFS: first come, first served. The first job to arrive at a work center is processed first.
SPT: shortest processing time. The shortet jobs are handled first and completed
EDD: earliest due date. The job with the earliest due date is selected first.
LPT. Longest processing time. The longer, bigger job are often very important and are selected first.
5) What are the advantages and disadvantages of the shortest processing time rule?

First and foremost, priority rules provide a groundwork for how jobs should be worked. The rules are most commonly used for process focused facilities such as clinics, print shops, and manufacturing job shops. Advantages normally include minimizing completion times, number of jobs in the system, job lateness, and maximizing facility ultilization. This rules is normally best for maximizing job flow and minimizing the number of jobs in the system. One of the major disadvantages is that long period jobs may be
