Key Terms
| Term | Definition |
| Target Speed | The speed target for a product on a given line. |
| Average Speed | The average speed of production during a run. |
| Good Output | The amount of product output from a run. Sensor Count is used, but if Finished Goods were entered, then that is used. |
Calculations
| Formula | Example |
| Time Lost Slow Running = ((1 / Average Speed) - (1 / Target Speed)) * Good Output |
Given: Average Speed = 5 unit/min Target Speed = 10 unit/min Good Output = 300 units Computation: = ((1/5) - (1 / 10)) * 300 = 0.1 * 300 = 30 min |
| Average Speed = Good Output / (Run Time - Downtime) |
Given: Good Output = 300 units Run Time = 80 min Downtime = 20 min Computation: = 300 / (80 - 20) = 300 / 60 = 5 units/min |
