Hello,

I am working on transportation scheduling problem obtained from CP optimizer document and modified as per my requirement. I am having data for scheduling 50 resources and observed default CPO is unable to give feasible solution in 4 hrs.  

Problem Size: 32916 variables & 744 constraints. 

Please suggest any parameters for tuning such scheduling problem?

Thank you.

Hi Anjikum,

You can share files with a DevWorks member. You need to go to the "Share" button (upper right corner of the page) and then click on "add files" to be able to add files to your profile. 

Then click on a forum member name and click on "Share a file". You will then be able to share files with that person. 

Regards,

Philippe

Hmmm very strange.
I suggest you something:
Could you try to check this using the "share a file" button?

Then, in the opened window, check that every files are selected (see the check boxes). If not, do it please.
