Yep, it works with 2GB of memory, with small datas so I really need to
simplify my model...

(As I said somewhere else in the thread, I would like to have something
like that :
subject to cont7 {i in 1..nbjob, j in 1..nbopparjob[i], k in
1..nbmachines, t in 1..BS-1} :
if (x[i,j,k,t]-x[i,j,k,(t+1)] == 1) then tpsopparjob[i,j]+sum{l in
1..nbmachines, r in (t+2)..BS}x[i,j,l,r]<=tpsopparjob[i,j]; )
