[rules-users] Optaplan6.0.0Beta1:chaining-simpleScore OK, DRL Score corruption

Requirement:Equip to tasks scheduling.Earlier tasks may not exceed a waittime to latest endtime for each job. 2 JOBs to plan each with 2 identical TASKs with only 1 EQUIPMENT anchor: J1 comprises T1,T2 and J2 comprises T1,T2. problem Fact: EQUIPMENT E1 planning Entity: TASK T1|duration=3|waittime=2 and T2|duration=5|waittime=3 OptaPlan Schedule attempt ------------------------- anchor(E1:T1J1,T1J2,T2J1,T2J2) - so T1J1 is pos1,T1J2 is pos2 etc : timings are 3+3+5+5 and respective waittimes are 2,2,3,3 Rule: get latest ending task by JOB and punish if waittime is exceeded between the tasks for that specific JOB. J1 latestendtime=11 which is T2J1 J2 latestendtime=16 which is T2J2 Punish if any task endtime for JOB exceeds waittime (so for J1: T2J1-T1J1=(11-6-2)*-1 = -3 (SOFT) - I believe that the score function remembers J1,T2J1 in position 3 and T1J1 in position 1 with SOFT score -3 OptaPlan Schedule attempt ------------------------- anchor(E1:T1J1,T2J2,T2J1,T1J2) - so T1J1 is pos1,T2J2 is pos2 etc : timings are 3+5+5+3 and respective waittimes are 2,3,3,2 Rule: get latest ending task by JOB and punish if waittime is exceeded between JOBs J1 latestendtime=13 which is T2J1 J2 latestendtime=16 which is T1J2 Punish if any task endtime for JOB exceeds waittime (so for J1: T2J1-T1J1=(13-6-2)*-1 = -5 (SOFT) - I believe that the score function remembers J1,T2J1 in position 3 and T1J1 in position 1 with SOFT score -5 Score corruption seems to occur as the DRL scoring function has 2 identical set of entities/values but with different score results! J1,T2J1 in position 3 and T1J1 in position 1 with SOFT score -3 J1,T2J1 in position 3 and T1J1 in position 1 with SOFT score -5 What has happened is that J2 has swapped its tasks around which are not(?) taken into account for a chaining DRL score function and hence does not see them as different. Q?: Am I correct in my assumption that the DRL score function has insufficient data to compare for my requirement? Q?: If so any ideas to resolve? -- View this message in context: http://drools.46999.n3.nabble.com/Optaplan6-0-0Beta1-chaining-simpleScore...
