Network Analyst Vehicle Routing Problem

DevinUnderwood2 — Fri, 16 Feb 2018 22:37:47 GMT

I am having trouble in what this error exactly means. Do you know how I can get more returned error information when I Solve ?

Warning: Orders (Name = "Location 2929") location does not have a corresponding network element. The network dataset needs to be rebuilt.
Error: Invalid input in the NA classes.

was it added after the network was built?

Yes it was. I constantly rebuild the network after each edit, to ensure where it may pose an issue.

try removing the point then or another rebuild ... after a shutdown, reboot, walk and a revisti... it is Friday, afterall

I removed that point (order) and the exact error prompted with another point and I can't rebuild unless I make an edit.

It is possible that you are loading these points with network locations. That is, the input point feature class has the network location fields such as SourceID, SourceOID, etc and it is using the old, stale locations. If that is the case, make sure to load by geometry. OR you can in the NA Window, right-click on the Orders and choose to Relocate All to update their location on the network.

Thank you for the advice.

I reloaded the orders based on geometry and Recalculate Location Fields - Unlocated (913 orders)

I reran the Solve but received the following error

Failure while working with internal OD cost matrix problem instance.

Error: General function failure

>I reloaded the orders based on geometry and Recalculate Location Fields - Unlocated (913 orders)

What does this mean? Did you relocate location fields and still get 913 unlocated OR did you load the orders again by geometry?

Are there other feature that need to be loaded again? Like depot, barriers, etc.?

Can you test that you are able to solve a route on that network dataset. And you can you try creating a new VRP layer and adding the orders/depots/route and resolve.

I loaded the orders based on geometry and still received errors, I proceeded to use Recalculate Unlocated .

Issue still not resolved. Yes, I already loaded Depot, Routes,Routes Zones.

I further tested by only loading one random order by Location and it successfully routed. I am not sure what this means.

I further tested by loading one random Order by Geometry and received the following

Warning: Orders (Name = "Location 10") is unlocated. (This is odd to me since I cleared out every record of the Name field for the orders, where is the solver getting the original Name from ?)

I created another VRP layer to further test, and I created another Network Dataset, yet still same errors.

If you are not able to load the locations by geometry then there is some problem going on with the network dataset or some settings like a spatial reference or search tolerance on the VRP layer.

What I was suggesting you to do is create a new Route layer, click two stops on the map and solve. Does that work? It would test that the network data is built correctly and that you are able to add locations by geometry.

I should preface my current status as follows , I have updated the previous Network road data by adding road segments and moving many orders. I am using the same search tolerance and spatial reference as before when I successfully ran the solver.

I can now successfully load as geometry, solve and generate a route when only using 2 order points (stops) which includes the Depot as departure and destination .

I can load multiple orders just not all 900 plus orders, not sure it is because certain areas of the road network may have errors.

Re: Network Analyst Vehicle Routing Problem

You can do a service area to check for connectivity issues. Create a service area layer, load your depot as the facility and set the service area layer properties to generate lines (instead of polygons), then set a large break value, say 120 minuutes and solve. Are all expected streets within the 120 minutes traveled by the service area?

Or you could also load all your orders as stops in the route layer and see if all can be reached.

I followed your steps and created a Service Areas Layer and it solved with the large set minutes break value, I reached and went past all order locations.

Re: Network Analyst Vehicle Routing Problem

JaySandhu — Tue, 20 Feb 2018 21:22:04 GMT

Are you able to route to all the stops?

And without looking at the data/layer, it is hard to say what is going on. I suggest that you call Esri Tech support so that we can follow up by getting your data and diagnosing it more.

Thanks,

I am able to load orders by route zones and get returned errors results, if any.

For example, one route zone only returned one error, "Network element not located"

I think I should be able to trouble using this method.

I have finally identified the one road segment/edge that is creating the issue.

The network is built successfully but the edge is not visible for the problem road segment and when I attempt to make edits on the segment and rebuild, I get build error.

Essentially preventing me from fixing the segment.
