Zoetermeer, Nederland ORTEC Voltijd

ORTEC helps many of the world's best-run organizations make better data-driven decisions. Our decision support software and data science expertise enable you to improve your business results and make a positive impact on the world.

Many businesses deal with fluctuating workloads, due to e.g. seasonal/weekly patterns or various disruptions. This has a direct effect on the number of employees that must be scheduled at any given time. With workforce being increasingly scarce, it is vital to make efficient use of workforce by scheduling employees at the right time (and the right place). Furthermore, it is important to acknowledge that employees have more influence than ever on their schedules (e.g. days on / off requests, working time preferences). Additionally, adherence to complex labor rules (e.g. enough daily/weekly rest) is imperative. Consequently, creating an employee schedule from scratch, with the objective of optimizing employee utilization, presents a significant challenge for planners.



A typical approach in solving rostering problems first translates the workload into shifts. For every day, there are different shifts, each with a start
- and endtime, and number of required employees to be assigned. Given the employees and their contracts, an assignment problem that matches the employees with the shifts gives a roster as a solution. In this research, you will investigate if a more integrated approach is available, where creating the shifts and assigning the employees is done simultaneously.

**What can you expect to do?**
- Review existing literature and methodologies related to the nurse scheduling problem, shift creation, employee assignment and integrated problems.
- Familiarize yourself with the (Dutch) labor laws and the existing dataset
- Design and implement more advanced and (partly) integrated approaches in which the two subproblems are not just solved sequentially.
- Evaluate the impact on the algorithm based on the solution, runtime etc.

**Who are you**:

- You are currently living in the Netherlands, studying at a Dutch University, and communicate fluently in Dutch or English, verbally and in writing.
- You are a master student in Operations Research, Econometrics, Applied Mathematics or another related field and looking for a graduation project.
- You like programming and can hunt for bugs.
- You have experience with heuristics.
- You are available for a minimum of six months to a maximum of nine months, starting in the first half of 2025..
- You can travel to the office (in Zoetermeer) at least twice a week

**What we offer**:

- Entrance to the most passionate powerhouse in applied mathematics. We share a drive to use our problem-solving skills to improve our planet, from the world at large to our own backyard.
- Inclusion in a company founded by graduate students back in 1981, which today still fosters its students by:

- Excellent supervision during your graduation project,
- Good internship allowance, laptop, and other office facilities,
- An open, kind, and fun culture.
- Access to Young ORTEC formal and informal events

**The next steps**:
If you're an enthusiastic graduate student seeking a hands-on experience that combines analytical thinking, multidisciplinary collaboration, and problem-solving, we invite you to join us on this exciting assignment by uploading your CV, motivation letter and grade lists (BSc and MSc in PDF if applicable).
