Hi alI

We have GAMS & CPLEX software and want to solve VRP problem.Could
anybody send me any type of VRP problem.

Thanks

Do it yourself. Use google. Start from here

Thanks for the reply. Actually I know about this websites but nothing
has been mentioned about GAMS & CIPLEX. I am not good in programming so
wanted to solve the problem in aforesaid softwares.

Maybe the reason why GAMS and CPLEX are not mentioned is that VRP is
not a linear programming problem. Actually, LP can be used on
various stages of solving process, but VRP is a bit more than LP.

Here is randomly selected link to materials that show where LP is
located within soem VRP solver.



Check also the book

The Vehicle Routing Problem Discrete Math (Siam Monographs on
Discrete Mathematics and Applications) by Paolo Toth , Daniele Vigo
This is the most up-to-date book on VRP and you will find a lot
about applicability of LP in various stages of solving VRP.

Hello,
I am student of industrial engineering , i need a guidance about Branch
and cut for the Capacited Vehicle Routing problem in GAMS.

Thanks a lot.

Read discussion on GAMS and VRP that started 10/02/2006 under the
same subject
