Robust Train Scheduling Problem with Optimized Maintenance Planning on High-Speed Railway Corridors: The China Case

Table 2

Decision variables.

Variables	Definition
	actual start/end time of maintenance window at major station on high-speed railway
	under scenario , .
	departure time of train on high-speed railway/normal-speed railway from station
	under scenario , .
	arrival time of train on high-speed railway/normal-speed railway at station
	under scenario , .
	= 1 if train stops at station under scenario ; =0, otherwise. .
	= 1 if train stops at station under scenario ; =0, otherwise. .
	= 1 if train departs from station earlier than train under scenario ;
	=0, otherwise. .
	= 1 if train runs on high-speed railway from major station to major station
	under scenario ; =0, otherwise. .
	= 1 if train waits at major station when there is a conflict with maintenance
	under scenario ; =0, otherwise. .
	= 1 if train switches from high-speed railway to normal-speed railway at major
	station under scenario ; =0, otherwise. .
