Please help! Could not able to place last 20 activities
« on: October 09, 2016, 11:45:17 PM »
Hi there,

Please help me in completing this timetable.  It took me more than 2 weeks, but still incomplete.  I do not understand why the last 20 activities failing to place.  That is, after the activity 489 it is hanging up.  Please help me soon.

Regards,
Syed.

i recommend to use weight only 100% or 0%; that will help you to find the bug faster. You can setup an other value again as soon as you found the bug.

Hi Volker Dirr,

Thanks for your quick response. Let me clarify once again about your reply.  Do you want me to keep weightage of 100% or 0% in place of 95% for all the activities.

Regards,
Syed.

yes. it is easier to see and understand bugs if you use only 0% or 100%.
(but i already tried to remove all min day constraints. your dataset is still impossible without them. so you need to remove some more constraints until it is solveable. then you hopefully understand why (a combination of the last and a previous removed constraint) it is impossible.
