Is there a way to model the following production processes:
1) splitting (e.g. cutting)
A (src product) -> (becomes) A (result product) + B (result product)?
and
2) combined working
A+B+C+ P (indivisibile work process that works A,B,C together) -> A'+ B'+ C'
(where A,B,C are source materials and A',B',C' processed materials).
