I have a problem where for a large number of orders (a few hundreds) there are multiple Orders to be delivered to any given address. Lets imagine there are 20 orders to be delivered to a single address. Logically one would expect that as long as all the constraints related to vehicle capacity aren't broken then single vehicle should get all the orders and go the this address alone.. Unfortunatelly orders are being distributed over more then single vehicle, which is not cost effective, might be confusing for a customer getting e.g. two deliveries instead of one.
Is JSPRIT capable to review order's deivery address and group them all if it is only possible from the vehicle capacity perspective? What might be wrong within the approach getting such results?
Thanks in advance for you help
