Multidepot Vehicle routing Problem

[mfurq...@gmail.com]

Hello,

I am having issue for making a network of multi-depot vehicle routing plan. Can anybody suggest help for that.

Hi,

I think the problem in our beginner's tutorial is similar to what you are looking for. Take a look at https://bit.ly/2LvcJvQ

Thanks for your response, but this article does not contain the multi depot vehicle routing plan, it is based on the single depot problem. 

 Kindly if possible than provide the relevant detail?

Regards

Hello Muhammad,

A multidepot problem is a simple extension of the single depot problem. You will use a set of Depots and the variables will get an extra index, for example Transport(d, c) where d is depot and c is customer.

If you can provide more context to your problem, the community might able to help you out more specifically.

This could be another relevant example : https://aimms.com/english/developers/resources/examples/practical-examples/vehicle-routing-cvrp

Hello Mohan,

thanks for your reply,  it was helpful for me  but  still this example is based on the single depot and i am looking for something which is based on multi-depot vehicle routing problem. 

I will appreciate you if you find me the relevant solution.

Hello Muhammad,

That is the only routing example that is available.

Like I mentioned already, extending a single depot routing problem to a multi depot routing problem is fairly straight forward.

You will have 3 sets - Depots, Customers and Vehicles.

You can have a parameter to specify which vehicles are available at which depot, or you can just say Depot 1 has 4 vehicles, Depot 2 has 3 vehicles and so on.

The variable could be something like X(v, d, c) - vehicle v left from depot d to customer c. The exact specification will depend on your exact problem statement.

Hello Mohan,

Thanks for your kind response. 

Exactly the same thing i am looking for but i am unable to do that. Actually i am lacking with possible language formulation for the parameters you describer earlier that suppose i want to allocate two vehicles depot 1 and two vehicles to other depot. what could be the possible formulation for that?
