Hello,
I am facing another problem!
I have achieve my model and it starts without any error.
But after a few time, it stops with this error, tat I cannot understand...

>>IloTupleRequestI::addGeWithoutCopy : IloNum request on non IloNum column

Can you please explain to me the meaning of this one ?
I have not found it in the OPL documentation...

Thanks for your help.

In your model, do you have any constraint that refer to a tuple and >=? If so could you post it with the detail on the tuple definition?

From the error message, it seems that you post a ">=" constraint on elements that are not of numerical type.

I checked but I do not seen any mistake such as the one you talked about...

Though, I think that the constraint the more likely to be the origin of this mistake is this one (it uses two tuple definition in the same variable, so maybe there is a misunderstanding)

forall(t in Time, u in Usines : t<Ttot)
Down[u] <=
sum(g in 1..Groupet+1[u]) e<t+1,u,g> * CaracNoeuds<t+1,u,g>.turb
- sum(g in 1..Groupe[t][u]) e< t ,u,g> * CaracNoeuds< t ,u,g>.turb
+ (Dt+1[u] - D[t][u])
<= Up[u];

with the Tuples :
tuple TripleIndex{int t;int u; int g;}
tuple Carac{float turb; float puis;float prim;float tele;}

used in :
{TripleIndex} Index = {<t,u,g> | t in Time, u in Usines, g in 1..Groupe[t][u]}
Carac CaracNoeudsIndex = ...

range Time = 1..Ttot
float UpUsines = ...
float DownUsines = ...
DTimeUsines = ...
and
dvar float+ eIndex in 0..1
I'm sorry, this is quite long and this might not be the error.
I have other constraint with CaracNoeuds< t ,u,g>.turb and if there is actually and error (why should it be one ? ok, there is one), it definately has to be with that writting

Thanks a lot !

Actually,
I removed all constraints containing the Carac tupe, and the mistake is gone!
Can you please tell me how can I write the model avoidin the error.
CaractIndex.turb should be right ? Doesn't it ?

Hello again,
Here's what I discovered :
All contraints work except this one (this is the error)

forall(t in Time, u in UsinesDiscretes : t<Ttot)
{
Down[u] <=
sum(g in 1..Groupet+1[u]) X<t+1,u,g> * CaracNoeuds<t+1,u,g>.turb
- sum(g in 1..Groupe[t][u]) X< t ,u,g> * CaracNoeuds< t ,u,g>.turb
+ (Dt+1[u] - D[t][u])
<= Up[u];
}

But, strangely, this one works :

forall(t in Time, u in UsinesDiscretes : t<Ttot)
{
Down[u] <=
sum(g in 1..Groupet+1[u]) X<t+1,u,g> * CaracNoeuds<t+1,u,g>.turb
- sum(g in 1..Groupe[t][u]) X< t ,u,g> * CaracNoeuds< t ,u,g>.turb
+ (Dt+1[u] - D[t][u]);

sum(g in 1..Groupet+1[u]) X<t+1,u,g> * CaracNoeuds<t+1,u,g>.turb
- sum(g in 1..Groupe[t][u]) X< t ,u,g> * CaracNoeuds< t ,u,g>.turb
+ (Dt+1[u] - D[t][u])
<= Up[u];
}

Ok, it might not be that akward, but this works :

forall(t in Time, u in UsinesContinues : t<Ttot)
{
Down[u] <=
sum(g in 1..Groupet+1[u]) e<t+1,u,g> * CaracNoeuds<t+1,u,g>.turb
- sum(g in 1..Groupe[t][u]) e< t ,u,g> * CaracNoeuds< t ,u,g>.turb
+ (Dt+1[u] - D[t][u])
<= Up[u];
}
It is another set for u and the e dvar
I don't see how the first constraint could be a problem when the second is not...

Problem solved.
Like 99% of the time, inattention...
Thanks for the explaining, it helped me a lot...
