Session Goal

The session aimed to refine and enhance a task scheduling model using Python and the OR-Tools library, focusing on implementing non-overlapping constraints and optimizing task scheduling algorithms.

Key Activities

  • Developed a Python-based task scheduling model using OR-Tools, incorporating constraint programming techniques.
  • Addressed and corrected various errors including non-overlapping constraints, TypeErrors, IndexErrors, and KeyErrors in the scheduling code.
  • Implemented dynamic CSV-based logic for task scheduling, ensuring tasks do not overlap by processing constraints from a CSV file.
  • Utilized a binary occupancy matrix and auxiliary variables to manage task scheduling and enforce occupancy constraints.
  • Integrated AddNoOverlap constraint within the task scheduling model to prevent task overlap while maintaining occupancy constraints.
  • Optimized the calculation of day and slot variables, ensuring alignment with the occupancy dictionary without unnecessary complexity.

Achievements

  • Successfully implemented a refined task scheduling model with enhanced non-overlapping constraints using OR-Tools.
  • Resolved multiple coding errors and optimized the scheduling process, improving the reliability and efficiency of the task scheduling system.

Pending Tasks

  • Further testing and validation of the scheduling model to ensure robustness across different scheduling scenarios.
  • Integration of additional task management features, such as incorporating recurring tasks and more complex scheduling constraints.
