I am trying to create a routing system for a school using a minimum number of vehicles. But the problem is that it not only involves time windows but also capacity constraints. Also starting no. of vehicles and location is unknown. So, I have to just work with customer locations and the time by which they should reach the school.

I wanted to know if someone has worked on something similar before or any open-source solution is available to resolve this issue that resembles mine like google OR-Tools etc.

Edit I am looking for an opensource python-based solution

Have a look at jsprit, the optimisation component of Graphhopper.

Mapotempo might help you. It's commercial and opensource.

They claim otherwise. And they share their code on Github.

Thanks for pointing out Mapotempo. If I may bring more precision, We have multiple projects which are or were open source.

First, Mapotempo-Web is a web application. It was open-source, but it is not anymore as we focus on sharing general purpose micro-services instead.

In your case @vsaadnet, you probably need Optimizer-API which provide a wrapper towards OR-Tools and VROOM. It also provides multiple internal resolution methods. This project in entirely open source. You can transmit your problem in JSON

If you only need a wrapper to use OR-Tools, we also provide this project The exchange format is in Protobuf
