Hello,
we use the ArcGIS Online VRP solver to route a fleet of 60+ vehicles and 12 different door heights. We are facing some challenges trying to model vehicle door heights using capacities.
The Challenge can be described as follows:
Truck 1 has a door height of 78”
Truck 2 has a door height of 89”
Truck 3 has a door height of 96”
Order 1 has a pallet stacked 48” High
Order 2 has a pallet stacked 85” high
Order 3 has a pallet stacked 92” high
Truck 1 can only pick up Order #1
Truck 2 could pick up Orders 1 & 2
Truck 3 Can pick up all 3 orders.
We tried using Capacities to solve this, but it will only work if driver is picking up only 1 order at a time as it tries to add the heights together. (48” + 85”) can’t be on the truck at the same time.
The only way I can think to solve this is to use Specialties, but that makes for a very long list of specialties. Especially if the fleet is larger.
With the above example we would have to use the following specialties:
96andbelow
89andbelow
78andbelow.
Truck 1 would only have the following:
“78andbelow”
Truck 2 would have the following:
“89andbelow 78andbelow”
Truck 3 would have to have all 3 listed:
“96andbelow 89andbelow 78andbelow”
And then the orders themselves would need to be classified accordingly.
In our current fleet where we have 60+ vehicles and 12 different door heights using specialties to address this does not sound like a practical solution. Is anyone aware of any other setting or workarounds to model this in the vrp solver ?
Thanks,
Ihab
