• The IWDSP 2021 workshop is the third event in the series started with IWDSP 2016 and IWDSP 2018 .
• Due to the uncertainty caused by the COVID-19 pandemic, the workshop is planned as a hybrid event, with both on-site attendance and virtual access.
• 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, malleable task scheduling, scheduling pliable jobs),
  • scheduling with various factors affecting job execution (ageing, 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 with maintenance activities),
  • scheduling under uncertainty (robust scheduling, stochastic scheduling, scheduling with explorable uncertainty),
  • other scheduling problems with parameters changing in time.
• 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.
