I am working on the multidepot-VRP problem an extension of your practical example capacitated VRP. I want to make a model in which vehicles will depart from their depots to serve different customers and turn back to the same depot where it started from. I made a rough model but facing some sort of errors. Kindly check and help me to resolve my model.
I shall be really thankful to you.
Looking forward for your kind response.

I modified the earlier model to work with 3 indices as you asked. Review attached project and let me know if you have any questions. I left comments for all variables and constraints.
