Being one of the most prestigious and most cited scientific journals in the fields of operations research and applied mathematics, the European Journal of Operational Research (EJOR) recently awarded its “EURO Award for the Best EJOR Paper 2021” to the paper “Solving the flexible job shop scheduling problem with sequence-dependent setup times” authored by WHU Professor Dr. Liji Shen, Stéphane Dauzère-Pérès, Professor at Ecole des Mines Saint-Etienne, France, and Adjunct Professor at Norwegian Business School, and Dr. Janis S. Neufeld of TU Dresden. “I hold EJOR in the highest regard and feel deeply honored to receive this award,” says Liji Shen.
In a sophisticated, iterative election process with a jury of distinguished experts in the relevant field, this paper was considered to provide the best theory and methodology out of 1,342 eligible papers published in EJOR in 2018 and 2019. The paper addresses the problem of scheduling highly diversified tasks and operations in the most flexible production systems to optimize both time- and cost-based criteria. Its specific focus lies on the complex set-up procedures of the various jobs entailed. Liji Shen and her co-authors have developed an extensive algorithm which enables companies to integrate sequence-dependent set-up times into their scheduling, which is well-known to be one of the hardest problems faced in Operations Research and Computer Science.
“This is a great success for Liji Shen and for WHU as well. The award is very well deserved, and we are proud to have outstanding researchers like Liji among our faculty,” says Professor Markus Rudolf, Dean of WHU.
