Different time windows for different vehicle

I have a case of vehicle routing problem delivery and pickup to make deliveries from the depot to the customer and pickup from the supplier to the depot for perishable food products. I consider suppliers and customers as orders and then I have 2 different types of vehicles to analyze in the following 3 scenarios:
1. Using a vehicle A has perishable facilities so that it can store products in the vehicle for 8 hours of working time.
2. Using vehicle B, which does not have perishable facilities, is only able to store products for 5 hours, so I set the time windows as follows:

	Time Windows Start	Time Windows End
Customer	10:00:00	15:00:00
Supplier	13:00:00	18:00:00
Depot	10:00:00	18:00:00

Vehicle departure from depot set in EarliestStartTime and LatestStartTime with the same value, 10:00:00

3. Combining scenarios 1 and 2 to solve simultaneously in one model to form a heterogeneous fleet vehicle routing problem, but I'm having trouble because I can't give special treatment to vehicle A free from time windows. I hope Esri Community can help me.
Thank you

Hello,

You could try using specialties to do this. Specialties on orders and routes ensure that the assignment honors specific requirements by an order and a driver or route. In this case, the customer and supplier orders can have specialty set to 'Perishable'. The Vehicles of type A should be set with the same specialty value 'Perishable'. That will make sure the perishable orders are assigned to Vehicle type A.

I hope this helps. Please let me know if you have any questions.

Thanks,

Shubhada
