I have implemented the single machine scheduling problem with release date constraints, with maximum lateness objective. The model file is:

using CP;

int nbJobs = ...;

range Jobs = 0..nbJobs-1;

int jobDurationsj in Jobs= ...;
int ReleaseDatesj in Jobs= ...;
int DueDatesj in Jobs= ...;
dvar interval jobs j in Jobs in ReleaseDates[j] .. maxint size jobDurations[j];//dichiarazione array di variabili intervallo

minimize max(j in Jobs)
maxl(0,endOf (jobs[j]- DueDates[j]));

The error message in the last line of the model is:

Operator not available for dvar interval - int.
