Two types of continuity constraints are considered: time continuity constraints and human continuity constraints. These constraints are characteristic elements of the routing and scheduling update.

We must respect the continuity of the schedule by keeping the start and end times unchanged from those set initially. In our case study, these start and end times are indeed contractual and cannot be called into question for each change in the schedule.

Next, we must respect so-called “human” continuity constraints. We define a continuity rate for each beneficiary, depending on the number of careworkers they know and the maximum number of different careworkers they can tolerate. Depending on the value of this rate, the intervention of employees still unknown to the beneficiary may be authorized. This makes it possible both to integrate new arrivals into the schedules and to compensate for the departure of careworkers.

To our knowledge, the constraints of time continuity are rarely studied in the literature, if at all. As for the constraints of human continuity, they represent a scientific challenge.
