Hi,
I am solving a VRP using GAMS. I was using MTZ subtour elimination constraints but I want to move to DFJ formulation, could you help me?
Thanks,
Have a look IOSR Journal of Engineering (IOSRJEN) www.iosrjen.org

Dear Carlos,
See the attached GAMS file for TSP with DFJ54 method. It was coded by Erwin Kalvelagen. His website is "yetanothermathprogrammingconsultant.blogspot.com".
You can learn from this example to code VRP.
