Adjusting the Analysis Setting of Model
The vehicle routing problem also has global properties that must be set. So far you have been working with attributes for individual model parameters such as orders, routes, and depots. Here you will adjust the analysis settings of the entire vehicle routing problem. These settings will influence all of the model parameters. Click on the Vehicle Routing Problem Properties button in the Network Analyst Window.
Navigate to the Analysis Settings tab. Verify that the Time Attribute is set to Minutes (Minutes). Set the Distance Attribute to Length (Meters). Verify that the Distance Field Units are set to Miles. This setting determines the units for other model attributes such as cost per unit distance, which in this scenario is dollars per mile. Set the U-Turns at Junctions to Allowed Only at Dead Ends. Leave all other settings as default and click OK.
