I am currently running it. Do I have to change the Obj attribute in the defining decision variable part? as in: ActionVar = {} for t in periods:   for i in decision:       ActionVar[t,i] = m.addV...

Hi, apologies for the late response. We have decided to use Lagrangian Relaxation to reduce the solving time, but not yet formed the updated obj function. This problem request can be closed. Thanks...
