Hi Vincent. Thanks for your answer. Finally, I decided to move to a full python implementation of the model. And I am working in the translation. Thanks! ------------------------------ Juan Esteban Calle Salazar ------------------------------

Hi Vincent, thanks so much for your message. Your suggestion has made me think if I should redefine the approach I was thinking to implement a Customised Benders Algorithm. To implement this type algorithm do you recommend me to go for a full Concert-Technology based approach? Another question. ...

Hi all, I am trying to code the Benders Algorithm to solve the Fixed Charge Transportation Problem. The code runs fine the first iteration: I can solve the dual subproblem and then the master problem, but I get this error in the second iteration: Oplrun process is not responding, you must relaunch ...
