Valid inequalities for the arc flow formulation of the railway crew scheduling problem with attendance rates
• We propose an arc flow model dealing with various practical requirements. • We define several problem specific valid inequalities. • For small instances (50–100 trips) solution times can be reduced by up to 94.79%. • For real-world instances the root relaxation can be increased by up to 3.02%....

Valid inequalities for the arc flow formulation of the railway crew scheduling problem with attendance rates |
| abstract |
• We propose an arc flow model dealing with various practical requirements. • We define several problem specific valid inequalities. • For small instances (50–100 trips) solution times can be reduced by up to 94.79%. • For real-world instances the root relaxation can be increased by up to 3.02%. |
