Dear scheduling researcher, We are delighted to announce the talk given by Erik Demeulemeester (KU Leuven). The title is "On the State of the Art in Proactive/Reactive Project Scheduling". The seminar will take place on Zoom on Wednesday, May 26 at 13:00 UTC. https://cesnet.zoom.us/j/93810859740?pwd=T3Z6d3hZSDM2UnFDRVQrMi9YMnY5Zz09 Meeting ID: 938 1085 9740 Passcode: 021060 You can follow the seminar online or offline on our Youtube channel as well: https://www.youtube.com/channel/UCUoCNnaAfw5NAntItILFn4A The abstract follows. The majority of publications in the extensive literature on resource-constrained project scheduling focus on a static deterministic setting for which a so-called baseline schedule is computed prior to project execution. In the real world, however, a project may be subject to considerable uncertainty. During the actual execution of a project, the baseline schedule may indeed suffer from disruptive events, causing the actually realized activity start times to deviate from the predicted baseline start times. This presentation focuses on robust project scheduling, in particular the development of effective and efficient proactive and reactive scheduling procedures. Proactive scheduling aims at generating robust baseline schedules that carry sufficient protection against possible schedule disruptions that may occur during project execution. Reactive scheduling procedures aim at repairing the baseline schedule when the built-in protection fails during the execution of the project. We discuss the fundamentals of state of the art proactive/reactive project scheduling approaches and discuss key directions for future research. The next seminar in our series will be given by Jinjiang Yuan (Zhengzhou Univ.) "Updated complexity results in single-machine primary-secondary scheduling for minimizing two regular criteria" and it will be held on June 9 at 13:00 UTC.
