Combined Rules         

MOD (modified operation due date)                                 PNj = max (t + oj, tdj)

(SPT-Tr) (Truncated SPT)                                            PNj = max (oj + r, tsj / nj*)

Here r is free parameters that influence the weight of the SPT component associate to the Slack component.

SL + SPT (max of slack and operation time) PNj = max (oj, tsj / wj*)

 CR + SPT (dynamic version of MOD rule) PNj = max (t + oj, t + oj. (tdj*- t)/wj*)
