In practice
Example: a morning appointment and a specialist repair
A coordinator has two service vans available from 08:00 to 17:00. One customer allows access only between 09:00 and 11:00. Another repair needs a specialist skill and 90 minutes on site. A third visit is a 30-minute check with a wider access window.
The model must reserve time for the work and travel, place the appointment within its allowed window, and keep the specialist repair on an eligible tour. If an optional visit cannot fit, a partial result can make that remaining work visible for review.
The example illustrates input requirements; it does not assert that these visits form a feasible solved route without addresses, travel estimates and the complete request.
