Overview

Some jobs may not have explicit locations but need to inherit them from related jobs. This is useful for scenarios like:
  • Pickup and delivery where delivery inherits pickup location
  • Multi-stop visits where subsequent stops inherit the previous location
  • Tasks that must be performed at the same location as another job

​
Example Request

This example demonstrates jobs with inherited locations where Job 2 will inherit its location from Job 1.

Key Points

  1. No Location Specified: Job 2 has no location field
  2. Relation Constraint: The same_vehicle relation ensures both jobs are served by the same vehicle
  3. Inherited Behavior: When Job 2 is scheduled after Job 1, it inherits Job 1’s location
  4. Travel Time: No travel time is calculated between jobs at the same inherited location
  5. Capacity: The capacity and load arrays must have matching dimensions

            "travelTimeInSeconds": 0,
            "distanceInMeters": 0
          },
          {
            "type": "end",
            "location": {"lat": 51.1079, "lon": 17.0385},
            "time": {
              "arrival": "2024-01-01T08:45:00Z"
            }
          }
        ]
      }
    ]
  }
}
Note how Job 2 shows the same location as Job 1 and has zero travel time/distance from the previous activity.

Use Cases

  • Service Continuity: Multiple services at the same customer location
  • Grouped Tasks: Tasks that must be performed together at one location
  • Dynamic Locations: Jobs where the location depends on the execution order
