• The IWDSP 2023 workshop is the fourth event in the series started with IWDSP 2016, IWDSP 2018 and IWDSP 2021.
• The workshop is organized by Algorithmics Research Unit, the Faculty of Mathematics and Computer Science, Adam Mickiewicz University in Poznań, Poland, and ZHAW Institute of Data Analysis and Process Design, Zurich University of Applied Sciences, Winterthur, Switzerland.
• Plenary lecture on scheduling over scenarios will be given by Leen Stougie (CWI, Vrije Universiteit Amsterdam and ERABLE, Lyon), abstract of the lecture is here.
• The aim of the workshop is to present recent research results on dynamic scheduling problems, in which job processing times, machine speeds or other parameters of the problems are variable and dynamically change in time.
• Main topics related to the workshop scope are
  • scheduling with variable job processing times (controllable job processing times, time-dependent job processing times, position-dependent job processing times, resource-dependent job processing times, discrete-continuous scheduling),
  • scheduling with various factors affecting job execution (aging, alteration, deterioration, learning, shortening),
  • scheduling on variable speed machines (energy-efficient scheduling, scheduling under time-of-use electricity tariffs, scheduling with rate-modifying activities),
  • scheduling problems with constraints on machine availability (scheduling with maintenance activities, scheduling on machines with non-availability periods),
  • scheduling under uncertainty (robust scheduling, stochastic scheduling, scheduling over scenarios, scheduling with explorable uncertainty),
  • scheduling with a partial, changing in time, data on jobs or machines (online scheduling, semi-online scheduling),
  • scheduling in non-classic models of job preemption (malleable task scheduling, scheduling pliable jobs, scheduling splittable jobs),
  • other scheduling problems with job or machine parameters changing in time (scheduling in data gathering networks, scheduling in health care systems, etc.).
• Topics not mentioned above are not excluded, however potential authors are asked to contact the Program Committee via e-mail to address stgawiej@amu.edu.pl.
