Decision Optimization

Hi,

I have two decision intervals "wp1_pieces & wp2_pieces"and I would like to combine them into a new decision variable "total_pieces". Is that possible?.

Here is how the two decision intervals look like

 dvar interval wp1_pieces[a in allActivities][b in St][1..maxPieces] optional size 100;
 dvar interval wp2_pieces[a in allActivities][b in St][1..maxPieces] optional size 200;

After the dvar interval total_pieces is made by combining the two intervals, I would like to minimise the makespan based on that interval:

dexpr float makespan = max(a in allActivities,b in St,j in 1..maxPieces) endOf(total_pieces[a][b][j]);

Thanks,
Mohamed

Are the first two intervals allowed to overlap, and do you know in advance which starts first and which ends first?

The two intervals can overlap but there is no information on which interval starts or ends before the other
