| Notations | Definition |
| Set | | | The set of all EMUs, dummy EMUs not included | | The set of S-EMUs, | | The set of L-EMUs, | | The set of works, dummy works not included | | The set of tracks for Work- |
| Parameters | | | The arrival time of EMU- | | The departure time of EMU- from the depot | | The standard operation time of EMU- for Work- |
