Nothing too fancy here; we will add on top of the existing Vehicle class. because for now Vehicle can only be linked to Delivery we won't step on this part as we want to work the link Vehicle <-> TaskList.

We will also introduce a concept of Trailer which is kind of a Vehicule as well.

We will introduce the concept of Warehouse. A Warehouse hosts many Vehicules. It has an address. To simplify things the Vehicules are assumed to be at a warehouse in the morning so we will use that as a starting point for our TaskList when we optimize stuff.

In the dispatch the dispatcher will be able to attach a bike and a trailer to a TaskList. The warehouse is linked to the

Then we will be able :

• to show their the weight and colum unit capacity in the dispatch + the total weight + volume units for parcels
• to fed the optimizer with capcacity (vehicle+trailer) and starting point (warehouse adress)

New pages :

• list warehouses + edit warehouses
• list trailers + edit trailers
• API list vehicles (with warehouse expanded)
• API list trailers
• API SETVEHICLE PATCH taskslist/id/vehicle
• API TRAILERS PATCH taskslist/id/trailer
