FET vs Orchestra Master Scheduler

FET creates timetables for schools, high schools, and universities, with automatic, semi-automatic, and manual allocation modes. Its time and room constraints can account for teacher and student availability, preferred times and rooms, gaps, working hours, and changes between rooms or buildings. It accepts flexible XML input and imports CSV; completed schedules can be exported as HTML, XML, or CSV. The maker states algorithm limits of 500,000 activities, 30,000 student subgroups, 30,000 rooms, and 30,000 buildings. FET runs on Linux, macOS, and Windows and is free software under the GNU Affero General Public License version 3, with no stated usage limits. The maker provides a forum and documentation, including manuals, instructions, tips, and frequently asked questions. Listed third-party tools convert FET XML results to Microsoft Excel or bring FET-compatible timetables into RosarioSIS. The maker also says it may help institutions with custom variants for changes that are not too difficult, or advise on how to implement them. Stated generation times range from under five minutes for simpler schedules to hours for extremely difficult ones.
