The area of staff/employee scheduling has been very active for decades with various successful applications from airline crew to manufacturing employees and health practitioners. With the aim of assigning staff to different tasks or shift patterns during a predetermined planning horizon, staff scheduling often aims to minimize costs while considering many hard and soft constraints, such as those dictated by regulations or preferences of the individuals. In this talk, I will present two particular applications that have rather distinctly different natures. In the first part of the talk, I will briefly review the state-of-the-art on the rather classical problem of nurse rostering. There will then a focus on more recent attempts integrating different methods to handle large-scale problems, with a discussion of our experiences on some integrations such as integer programming and variable neighbourhood search, and a brief outlook to the future. The second part of the talk will focus on the vessel crew scheduling problem, in particular for offshore supply vessels (OSVs). The maritime setting presents challenges due to the variety of tasks to be carried out, the varying experience levels of crew, and long duty times. A brief overview of the rather limited literature will be followed by a discussion of some effective integer programming formulations as well as effective solution methods, such as customized heuristics and Benders decomposition. I will conclude this part of the talk with some preliminary computational results.

Sobre o Palestrante:
Kerem Akartunali is a Senior Lecturer (Associate Professor) in the Department of Management Science at Strathclyde Business School (Glasgow, UK), and also holds a Visiting Professor position at Institute of Mathematics and Computer Science (ICMC-USP) of University of São Paulo. After completing his Ph.D. in 2007 at the University of Wisconsin-Madison (USA) on lotsizing, he worked as a postdoctoral research fellow in the Department of Mathematics and Statistics at the University of Melbourne (Australia) on airline planning and scheduling problems. Kerem’s research expertise lies primarily in integer programming and its applications, in particular in lot-sizing, transportation scheduling/planning, radiation treatment planning optimization and nurse rostering. Kerem's research has been funded by various bodies/organizations including EPSRC, Scottish Funding Council, Capita and USAF Office of Scientific Research. He is an active member of INFORMS, Mathematical Optimization Society, and The OR Society. He worked with many organizations, including First Milk, NHS, Scottish Power, Scottish Southern Energy and Technip, in a variety of projects ranging from short-term consultancy to long-term research partnerships.
