I am using vehicle routing problem to generate route for a list of orders for 4 weeks.
My scenario is I have some orders which have to be visited 4 times in 4 weeks i.e once in a week.
For these type of order I have set different timewindow i.e for 1st week Monday to Saturday of 1st week is the Timewindow start and end. Like that for other weeks also.
Now I want all the 4 visits of the same order to be visited by same Vehicle.
Now I am not sure how to set same vehicle for a order which have visit frequency of 4.
