Dear scheduling researcher, We are delighted to announce the talk given by Pieter Smet (KU Leuven). The title is "Robustness in personnel rostering". The seminar will take place on Zoom on Wednesday, March 20 at 14:00 UTC. Join Zoom Meeting https://cesnet.zoom.us/j/99775148608?pwd=UkgwT25wRXpHL1k3dzJhbkFqc2pkdz09 <https://cesnet.zoom.us/j/99775148608?pwd=UkgwT25wRXpHL1k3dzJhbkFqc2pkdz09> Meeting ID: 997 7514 8608 Passcode: 885832 You can follow the seminar online or offline on our Youtube channel as well: https://www.youtube.com/channel/UCUoCNnaAfw5NAntItILFn4A The abstract follows. In this talk, we study the problem of generating personnel rosters that are robust with respect to disruptions caused by employee absenteeism. If an employee unexpectedly becomes absent, they must be replaced by another employee. This in turn may affect the working hours of other employees, creating an undesirable ripple effect that changes a large part of the roster. We investigate how making use of on-call duties may avoid such large perturbations. We begin by first introducing a metric to quantify the robustness of a roster, which is then used to generate sufficiently robust rosters. In the second part of this talk, we discuss the conditions under which machine learning can lead to better solutions. A novel methodology is presented to determine the minimum prediction performance required to outperform the non-data-driven rostering approach. The next talk in our series will be: André Rossi (Universite PSL) | April 3 | Maximizing stability of assembly line balancing schedules under uncertain task duration For more details, please visit https://schedulingseminar.com/ With kind regards Zdenek, Mike and Guohua -- Zdenek Hanzalek Industrial Informatics Department, Czech Institute of Informatics, Robotics and Cybernetics, Czech Technical University in Prague, Jugoslavskych partyzanu 1580/3, 160 00 Prague 6, Czech Republic https://rtime.ciirc.cvut.cz/~hanzalek/
