Hi,

In the attached model, I am getting an error "Operator not available for && int ..." . I have built this same program in C++ and didn't get error. How should I do the same in OPL?

Thanks

Hi,

I am not sure about what you intend to do but you cannot do affect in a constraint.

Maybe

forall(w in TanksInd)
              {   if (Routes[i][d][w] == 1)
                   {Tmax >= t[i][item(Tanks,w)] + LTravelTime[item(Tanks,w)][last(Tanks)] - (1-RouteAssign[i][d])*M; }
            }      

could help

Regards
