How to cater overlapping routes issue in Network analyst VRP solver?

SarahOvais

Considering no. of outlets that are to be visited by different vehicles (Vans, Bike, Truck) etc depending on the demand of the outlets & capacity of the vehicles, the routes generated in VRP have overlaps, keeping in mind that each vehicle should visit exactly 50 outlets. networkanalyst vrp geonet answers geonet #geo-visualization

Hi Sarah - Thanks for asking your questions and welcome to the GeoNet community! I wanted to let you know that we're moving your question from the GeoNet Help group to the NetworkHarborInc‌ space so our Esri and user subject matter experts can further help answer this and future questions. So you're aware on how and where to post your questions, here's a few quick tips and reminders:

First, use the GeoNet search (top right corner by your profile icon) to search and see if your question has already by asked/answered previously.
If not, than we suggest reviewing the GeoNet Community Structure, to find the most relevant space to post your question.
The GeoNet GeoNet Help group is for questions and tips on how to use the GeoNet community platform not the Esri ArcGIS platform. Following steps 1 & 2 above will give you the best results for getting Esri product questions answered.

I have tagged the network analyst group as well, but no response so far.
I have checked; I couldn't find anything on my query on the forum.
I was hoping if someone can help me, or need more details.
Thanks

Hello Sarah,

I'm not quite sure what you are asking. Are your routes overlapping (crisscrossing each other) and you are asking for how to make it so they don't overlap? Can you give a little more detail about what you are doing and what issue you are running into.

Thanks,

Heather

Hi.
The issue is that the maximum no. of outlets served by each salesman is 50 in VRP.
Now when the VRP is executed, salesman one covers let's say 25 outlets from area one, another 10 from neighbouring area and rest from another. And 2nd salesman covers remaining 25 from area one and rest of the 25 from another and hence causing the overlap resulting in resource inefficiency.

Hi Sarah,

You could try route zones for the different salesman. That would keep them within a region. The other option is to use seed points. That tends to give better clustered results without having to predesignate areas for the different salesman.

Hi Heather, I have used the route seed points. Depending on the nature of the data set, I couldn't always get clusters with no overlaps. We are talking about huge dataset that's random, for reference I can provide the sample data as well.
Even though route seed points give accurate results incase of generating routes for many salesman, but this doesn't hold true in all cases.
