Jonas Rothhardt developed and enhanced the CombiRWTH/StaffScheduling system over three months, focusing on both feature delivery and maintainability. He implemented core scheduling objectives, such as honoring pre-planned shifts and introducing an alternating free weekends policy to improve fairness and reduce manual adjustments. Using Python, OR-Tools, and JavaScript, Jonas expanded the system’s constraint programming capabilities, improved the web interface with Bootstrap and Jinja2, and restructured documentation for better onboarding. His work included architectural refinements, robust error handling, and data visualization enhancements, resulting in a more reliable, scalable scheduling platform that aligns with workforce planning and supports ongoing developer contributions.

Aug 1, 2025August 2025: Focused feature delivery for CombiRWTH/StaffScheduling. Delivered the Alternating Free Weekends Objective to penalize two consecutive weekends with the same status (both free or both assigned), with comprehensive documentation and integration into the solver. This enhancement improves scheduling fairness and automated decision-making for weekend staffing, reducing manual adjustments and enabling more predictable workloads. No major bugs were fixed this month; priorities centered on feature delivery, stability, and verification of the new objective within the solver. Commit reference included for traceability: 0e7814a8c707cd5a3e5d4853f71563fdef6b8725.
