| Assignment method | A special case of the transportation method of linear programming that is used to allocate a specific number of jobs to the same number of machines.
|
 |
|
|
| Backward scheduling | Starts from some date in the future (typically the due date) and schedules the required operations in reverse sequence. Tells the latest time when an order can be started so that it is completed by a specific date.
|
|
|
|
| Dispatching | The activity of initiating scheduled work.
|
|
|
|
| Finite loading | Each resource is scheduled in detail using the setup and run time required for each order. The system determines exactly what will be done by each resource at every moment during the working day.
|
|
|
|
| Forward scheduling | Schedules from now into the future to tell the earliest that an order can be completed.
|
|
|
|
| Infinite loading | Work is assigned to a workcenter based on what is needed over time. Capacity is not considered.
|
|
|
|
| Input/output (I/O) control | Work being released into a workcenter should never exceed the planned work output. When the input exceeds the output, backlogs build up at the workcenter that increase the lead time.
|
|
|
|
| Johnson’s rule | A sequencing rule used for scheduling any number of jobs on two machines. The rule is designed to minimize the time required to complete all the jobs.
|
|
|
|
| Labor-limited process | People are the key resource that is scheduled.
|
|
|
|
| Machine-limited process | Equipment is the critical resource that is scheduled.
|
|
|
|
| Manufacturing Execution System (MES) | An information system that schedules, dispatches, tracks, monitors, and controls production on the factory floor.
|
|
|
|
| Priority rules | The logic used to determine the sequence of jobs in a queue.
|
|
|
|
| Sequencing | The process of determining which job to start first on a machine or workcenter.
|
|
|
|
| Shop-floor (production activity) control | A system for utilizing data from the shop floor to maintain and communicate status information on shop orders and workcenters.
|
|
|
|
| Workcenter | An area in a business in which productive resources are organized and work is completed.
