Shunting Strategy for Placing-In and Taking-Out Wagons on Branch-Shaped Freight Operation Network with Simulation Method

Table 1

List of all Arena modules used in the simulation model.

Module	Name	Module	Name
Create	Wagon group i	Pickstation	Choose the first placing-in operation site
Assign	Destination is operation site i	Pickstation	Travel to next placing-in operation site
Assign	Start time i	Pickstation	Travel to first taking-out operation site
Assign	Completion time i	Pickstation	Travel to next taking-out operation site
Assign	Completion helper i	Pickstation	Travel to the first shift-out operation site
Assign	Taking-out time i	Pickstation	Travel to next shift-out operation site
Assign	Taking-out helper i	Decide	Finish placing-in wagons
Assign	Shift-out time i	Decide	Wait
Station	Span shift-moving helper i	Decide	Finish taking-out wagons
Station	Operation site i	Decide	Last placing-in operation site
Station	Shift-out operation site	Decide	Span-shift-moving shunting operation is finished
Station	Shift-into operation site	Pickup	Pickup wagon group
Station	Shunting yard	Pickup	Pickup double operation wagons
Request	Call the locomotive	Route	Return to shunting yard
Request	Locomotive	Route	Travel to corresponding shift-into operation site
Batch	Accumulate local wagons	ReadWrite	Output start time i
Separate	Detach all local wagons	ReadWrite	Output completion time i
Dispose	Departure yard	ReadWrite	Output taking-out time i
Search and remove	Select specific wagon group	ReadWrite	Output shift-out time i
Process	Operation	Hold	Hold wagon group in current operation site
