Iterating backhaul

Due to the iterative nature of the backhaul process, it is suggested to automate the route modifying parameters. This can be done in ModelBuilder or as a standalone Python script.

Backhaul model

Sample model with iterator — A sample ModelBuilder diagram with an iterator on daisy chain. As the iterator increments by one, the backhaul process will run with a different daisy chain value.

Backhaul script

Backhauling the remote assets with different daisy chain values.

                import arcpy

# Import toolbox and check out NA extension
arcpy.env.workspace = "C:/Solutions/BackhaulOptimizationA4TC/MapsAndGDBs"
arcpy.ImportToolbox("Tools/Backhaul.pyt", "backhaul")
arcpy.CheckOutExtension("Network")

for i in range(1, 11):
   arcpy.backhaul.BackhaulAssets("Assets.gdb/RemoteAssets",
                                 "Assets.gdb/FixedAssets", 
                                 "Assets.gdb/NearTable"
                                 "D:/streetmap/ClosestFacility.lyr",
                                 arcpy.env.workspace,
                                 daisy_chain=i)

arcpy.CheckInExtension("Network")
