Run Time
| Run Time Formula | 
| \( RT \;=\; \dfrac{ PPT }{ ST } \) | 
| Symbol | 
| \( RT \) = run time | 
| \( PPT \) = planning production time | 
| \( ST \) = stop time (manufactures process time, but with no planned or unplanned stops) | 
Run time, abbreviated as RT, is the scheduled production time and its running.
