Hi,
I have declared a decision variable like this:
dvar int setup[Options,Slots] in 0..1;

and I have an error message that I can't use a dvar int for constraint
I don't know why?!

I tried to imitate what you're doing but I was not able to reproduce your problem. Are you sure that the declaration with the ranges of  options, slots is OK? probably sharing a bigger chunk of the code would help understand the reason of the error...

cheers

Hello,

i am facing the same error but with different statement related to scheduling:

if i used:
int nbPkt2 = 3;
int nbTsk2 = 9;
range Ap2 = 0..nbPkt2*nbTsk2-1;
int durationAp2i in Ap2 = 1;
dvar interval operationsi in Ap2 size durationAp2[i];

constraints {

forall (j in Ap2 : j mod nbTsk2 <= nbTsk2-5)
endBeforeStart(operations[j], operationsj+1);
}

it does work but when using :

int nbPkt2 = 3;
int nbTsk2 = 9;
range Pkts = 0 .. nbPkt2-1;
range Tsks = 0 .. nbTsk2-1;
range Ap2 = 0..nbPkt2*nbTsk2-1;
int Demandi in Pkts, j in Tsks = 1;
dvar interval operationsi in Ap2 size durationAp2ftoi(j/nbTsk2),j mod nbTsk2;

constraints {

forall (j in Ap2 : j mod nbTsk2 <= nbTsk2-5)
endBeforeStart(operations[j], operationsj+1);
}

it gives me two main errors:
Invalid initialization expression operations
bad conversion between integer object and numeric object

can you help me?

Thanks
