Scheduling Scheduling has to do with establishing the timing of the use of equipment, workstations, facilities, and personnel. Sequencing is the determination of of order in which jobs waiting at a workstation are to be processed. Simple Scenario: Workstation A3 B10 C20 D2 E5

Terms/Performance Measures Job flow time - length of time a job is at a particular work center, actual processing time and any waiting time. Job lateness Makespan - total time needed to complete a group of jobs Average number of jobs – total flow time / makespan (at a work center)

Possible Priority Rules First come, first served (FCFS): Jobs are processed in the order in which they arrive. Dominant in service, mainly because of fairness and inability to estimate processing times. Shortest processing time (SPT): Jobs are processed shortest job first. Low average number of jobs at a workstation. Low average tardiness. Lower inventories. Earliest due date (EDD): Jobs are processed earliest due date first. Addresses lateness and minimizes lateness. Minimizes job tardiness. Critical ratio (CR): Jobs are processed according to the smallest ratio of time remaining until due date to processing time remaining. Low average tardiness. Slack per operation (S/O): Jobs are processed according to slack time divided by number of remaining operations. Jobs with little slack and a large number of remaining operations will be processed first. Used when considering remaining processing time and remaining number of operations.

Johnson’s rule A sequencing technique for minimizing total completion time for a group of jobs. -Job times must be know in advance -All jobs follow the same two-step sequence -Two work centers that each job must go through Example: JobMach1Mach2 A32 B68 C56 D74
