Fixed duration at depot

This constraint defines the minimum loading or unloading time specific to a resource, regardless of the depot used. Additional time may be added based on the following constraints: Loading/Unloading duration per unit at depot (resources), Fixed loading/unloading duration (depots), and Loading/Unloading duration per unit (depots).

Format: HH:MM, HH:MM:SS, or MM

Example: For a pickup, the resource will remain at the depot for the duration specified in Loading/Unloading duration at depot, regardless of the quantity collected. This time may represent fixed operations such as using the vehicle’s tailgate. It is added to the base time spent at the customer location, as defined by the Visit duration constraint.

This duration depends on the vehicle capacity.
