Shop floor control – order scheduling
Concerned with machine loading and job sequencing:
Machine loading – allocating orders to work centers.
Job sequencing - determining the order in which parts are processed through a given work center.
Priority control – maintains the proper priority for the production orders under the dispatching rules: first-come-first-serve – jobs are processed in order received earliest due date – orders with earlier due dates have higher priority shortest processing time – those finished faster have higher priorityleast slack time – jobs with least slack time have higher priority critical ratio – ratio of time remaining until due date divided by remaining
