Job relations

In this example we will show you how to use job relations. Job relations are defined on jobs. They can be used to
express different links between jobs:

  • SEQUENCE: the jobs need to be visited in the given order
  • DIRECT_SEQUENCE: the jobs need to be visited in the given order, one after the other
  • SAME_TRIP: the jobs need to be visited in the same trip, the sequence does not matter
  • SAME_TIME: the jobs need to be visited at the same time, the assigned resource will obviously be different
  • PICKUP_AND_DELIVERY: the jobs need to be in the same trip and the pickup needs to happen before the dropoff. (special case of job relation)
