Chapter 15
1. Forward scheduling – Scheduling that begins the schedule as soon as the requirements are known.
2. Backward scheduling – Scheduling that begins with the due date and schedules the final operation first and the other job steps in reverse order.
3. Loading – The assignment of jobs to work or processing centers.
4. Input – output control – A system that allows operations personnel to manage facility work flows by tracking work added to a work center and its work completed.
5. ConWIP cards – Cards that control the amount of work in a work center, aiding input-output control.
6. Gantt charts – Planning charts used to schedule resources and allocate time.
7. Assignment method – A special class of linear programming models that involves assigning tasks or job resources.
8. Sequencing – Determining the order in which jobs should be done at each work center.
9. Priority rules – Rules used to determine the sequence of jobs in process-oriented facilities.
10. First come, first served (FCFS) – Jobs are completed in the order they arrive.
11. Shortest processing time (SPT) – Jobs with the shortest processing times are assigned first.
12. Earliest due date (EDD) – Earliest due date jobs are performed first.
13. Longest processing time (LPT) – Jobs with the longest processing time are completed first.
14. Critical ratio (CR) – A sequencing rule that is an index number computed by dividing the time remaining until due date by the work time remaining.
15. Johnson’s rule – An approach that minimizes processing time for sequencing a group of jobs through two work centers while minimizing total idle time in the work centers.
16. Finite capacity scheduling (FCS) – Computing short-term scheduling that overcomes the disadvantage of rule-based systems by providing the user with graphical interactive computing.
17. Level material use – The use of frequent, high-quality, small lot sizes that contribute to just-in-time production.
Chapter 16
1. Just-in-time (JIT) – Continuous and forced problem solving via a focus on throughput and reduced inventory.
2. Toyota Production System (TPS) – Focus on continuous improvement, respect for people, and standard work practices.
3. Lean operations – Eliminates waste through a focus on exactly what the customer wants.
4. Seven wastes – Overproduction, Queues, Transportation, Inventory, Motion, Overprocessing, Defective product.
5. 5Ss – A lean production checklist: Sort, Simplify, Shine, Standardize, Sustain.
6. Variability – Any deviation from the optimum process that delivers perfect product on time, every time.
7. Throughput – The time required to move orders through the production process, from receipt to delivery.
8. Manufacturing cycle time – The time between the arrival of raw materials and the shipping of finished products.
9. Pull system – A concept that results in material being produced only when requested and moved to where it is needed just as it is needed.
10. JIT Partnership – Partnerships of suppliers and purchasers that remove waste
