Title: Subject: Question about swapping morning and afternoon sessions in a final timet
Post by: Alami mohammed on October 04, 2025, 07:28:11 PM


Hello Mr. Liviu,

I would like to ask about a technical question regarding an already completed and valid FET timetable.

Once I have generated a final timetable, how can I keep the exact same order of activities, but simply swap morning sessions with afternoon sessions (for example, moving 8:00–12:00 activities to 14:00–18:00, and vice versa)?

Is there a way to achieve this by editing the XML file or any other configuration file directly, so that I don't need to regenerate the timetable from scratch?

Thank you in advance for your help and for your continuous efforts to improve FET!

Best regards,
Alami Mohammed

Hello, Mr. Alami,

You are welcome! Thank you!

It is easy: swap odd FET days with even FET days in the fet XML data file, and deactivate all the time and space constraints which are not activity preferred starting time / activity preferred room (only so that you can generate the timetable, not more than necessary). I attach an example, imperfect, because I deactivated at least one activity preferred starting time which should not have been deactivated.

Yes, that, or swap in the section <Days_List>. In my example above I did like that.
