            Using GraphHopper in a building - Indoor Navigation
            Asked 2019-Mar-29 at 05:56

            I'm trying to use GraphHopper core to create a indoor navigation app. I already create a .osm file of the building(with 2 floors) containing all the possible routes inside the building.

            The problem that I'm facing now is that there is no way to filter points by floors, i.e, when I make a call to the web API /route the points only have lat/lon and no floor or something similar to distinguish between to points with the same lat/lon.

            How can I solve this problem? Anyone can give me some hints to accomplish this task?

            Side question: How can integrate GraphHopper jsprit with GraphHopper core? Where can I find some documentation about that?

            This is a missing feature. See this issue https://github.com/graphhopper/graphhopper/issues/646

            You could attach a z-component for every edge (or node) and use an EdgeFilter to pick the correct floor.

            Solution of Jsprit is not correct if shipments have multiple size of dimension
            Asked 2019-Jan-09 at 10:22

            I am new to Jsprit. I tried to use multiple size of dimension in my shipment list. For example, some shipments I added size of dimension with WHEELCHAIRSPACE_INDEX and some shipments I use PASSENGERSEATS_INDEX in my createJob(). However the output seem like wrong.

            When you built your cost matrix, you only specified travel time, not distances.

            By default, the cost of an unassigned job depends on the the (maximum) distances between the pickup and delivery locations. Since distances aren't set, there is no penalty for unassigned jobs.

            An easy solution would be to add some reasonable distance metric when you build the cost matrix:

            Is there a way to obtain the output/store results in variables other than outputting solutions to an xml file using vrpxmlwriter?

            I tried to get the results with dom parser, xpath and family and can proudly say that I made a complete mess!! Common Jsprit team you've made this beautiful piece of art, why couldn't you provide us with functions like bestSolution.getAllVehicles() ??

            Judging only from the source code, shouldn't you be able to easily extract all the vehicles from the bestSolution instance?

            Assuming bestSolution is of type VehicleRoutingProblemSolution, I'd expect something like this to work:

            Jsprit using maven so it is very simple to use. Just download source code and open pom.xml file in Intellij-idea. You can have access all the source code and examples.

            ANSWER

            Answered 2017-Apr-24 at 03:05

            Because using two vehicles returns smaller total cost (10.28538328578604) than using one vehicle (10.537319187990756) in your case.

            If you would like to force it to use only one vehicle, you can either set fleet size to FINITE or set a fixed cost to the vehicle type.
