Data Science Project: Exploring Flexible Scheduling for Nurse Rostering

2 weken geleden

Amsterdam, Noord-Holland, Nederland ORTEC Voltijd

ORTEC is a leading provider of decision support software and data science expertise. We help organizations improve their business results and make a positive impact on the world.

Hospitals and other businesses operate 24/7, requiring employees to work night shifts and adhere to labor laws governing scheduling. These rules ensure employees get sufficient rest after night shifts and require enough rest in general on a daily and weekly basis. The complex rules combined with personal preferences make for an interesting scheduling puzzle to solve using heuristics.

We currently use a heuristic that explores different solutions with local search, but the algorithm does not allow swaps (moves) that violate any hard constraints. Your challenge is to test which temporal violations lead to better final solutions and quantify the optimal penalty values for relaxing them.

What can you expect to do?

  • Review existing literature and methodologies related to the nurse scheduling problem, heuristics, and ways to relax hard constraints with penalties.
  • Familiarize yourself with the Dutch labor laws and the existing dataset.
  • Design and implement ways to relax the hard constraints throughout the search process considering the difficulty of fixing each violation.
  • Evaluate the impact on the algorithm based on the solution, runtime, etc.

You are:

  • A master student in Data Science, Operations Research, Econometrics, Applied Mathematics, or another related field looking for a graduation project.
  • Experienced with heuristics such as Variable Neighborhood Search.
  • Able to program and enjoy hunting for bugs (in C# or willing to learn).
  • Living in the Netherlands, studying at a Dutch University, and fluent in Dutch or English, verbally and in writing.
  • Available for a minimum of six months to a maximum of nine months, starting in October or November 2024.
  • Willing to travel to the office (in Zoetermeer) at least twice a week.

We offer:

  • Entrance to a passionate powerhouse in applied mathematics where we share a drive to use our problem-solving skills to improve our planet.
  • Inclusion in a company founded by graduate students back in 1981, which still fosters its students by:
    • Excellent supervision during your graduation project.
    • A good internship allowance, laptop, and other office facilities.
    • An open, kind, and fun culture.
    • Access to Young ORTEC formal and informal events.

Salary: €2,500 - €3,000 per month, depending on experience.

Benefits:

  • Development programs tailored to your individual needs and function requirements.
  • Opportunities to attend courses and seminars.
  • Challenging, practical hands-on experience with opportunities to work abroad.
  • An open, informal, cooperative, and positive atmosphere.
