Just saw a demonstration of Acumen wherein it was able to identify redundant logic ties (unnecessary). Was not able to find the same capability in either P6.7, Pertmaster 8.53, or Claim Digger. Has anyone seen this feature anywhere else? Could be useful to simplify schedules and reduce processing time. Any thoughts appreciated. Thanks.

Acumen Fuse does multiple types of logic checks including redundant logic, cycles, activities out of sequence, etc. You can download a trial copy of Acumen Fuse from http://www.projectacumen.com/fuse/trial/
Thanks all for your comments. My experience suggests that there are 'sloppy' schedules out there with complex, convoluted logic that could use tightening/simplification. I regard this as a tool that I would like to have in reviewing schedules - just like knowing open ends. I would like to be able to decide if the logic is sound or superfluous, but have never seen this tool before. If you have seen something similar, I would appreciate a 'heads-up'. Again, thanks.
In addition, the effort and time on programming such irrelevant functionality outweigh the benefits. Today more advanced software allows for the use of different calendars per link and allows multiple links between two activities.
For example, you migth have 2ea SS links between any two activities each with different lag and different calendar. At one time span; one link, the other link(s), or even both or all might be driving links. Deleting links without being very careful can invalidate your model. The algorithm for advanced software can be quite time consuming. Just add to the complication different types of lag, that is either duration and/or volume lag(S) plus conditional switches.

hi all
I Agree with Mr. Vladimir because form my exp. critical path for any project will change every time updating the schedule .
and this redundant links may become critical in future , unless the relation in not logic we have to keep them.
if anyone disagree, please explain to me (share your experience)
Good luck to all

Assuming no lag link 1-2 is redundant.
Unless you do not know what you are doing you will have very few, if any, redundant links you did not create on purpose, they will do no harm but might be a lifesaver if you latter on delete a link and forget about such prior predecessor link. A functionality to clean up redundant links, some of which I create on purpose; I find it irrelevant and even unwelcomed.

The dependencies may be driving or not. Did I understand correctly that redundant means non-driving dependencies?
It is dangerous to remove non-driving dependencies because schedules may change for many reasons. It is safer to enter all dependencies and the software will satisfy all of them.
