Routing Rules to Locate Resources
When a resource is in the field, the application sends the GPS coordinates of the resource to the routing engine, if they're available. This helps Routing identify the location of the resource.
For urgent routing, the application requires recent GPS coordinates to determine the resource’s current position. If valid GPS coordinates are not available, the resource is not considered for immediate assignment and becomes eligible once updated coordinates are received.
The following rules describe how the application determines a resource’s location for routing:
-
If the resource’s GPS coordinates are obtained between 0–20 minutes, the GPS coordinates are used.
-
If no GPS coordinates are available, or if GPS coordinates are greater than 20 minutes, the resource's Start Location is used if it is available.
-
If no GPS coordinates are available, or if GPS coordinates are greater than 20 minutes, and no Start Location is assigned to the resource then the resource's location remains undefined.
-
If the resource's GPS coordinates are newer than the address of the started or completed activity and the resource is at a distance more than 20 minutes from the address of the started or completed activity (using airline distance and default company airline distance speed), the GPS coordinates are used.
-
If no GPS coordinates are available, or if GPS coordinates are older than the address of the started or completed activity, or the resource is at a distance less than 20 minutes from the address of the started or completed activity (using airline distance and default company airline distance speed), the address of the started or completed activity is used.
Let’s say a resource completes a non-travel activity or an activity that doesn’t include address coordinates and then proceeds for the next activity that involves travel. The application uses the current GPS location of the resource after the route has been activated as the starting point of travel.
