RETRACTED ARTICLE: A nonanticipatory policy for stochastic seru scheduling problems

We, the Editors and Publisher of Journal of the Operational Research Society, have retracted the following article: Zhang, Z., Gong, X., Song, X., Yin, Y., Lev, B., & Zhou, X. (2023). A nonanticipatory policy for stochastic seru scheduling problems. Journal of the Operational Research Society, 1–12. https://doi.org/10.1080/01605682.2023.2182723. Since publication, significant concerns have been raised about the fact that this article appears to have substantial overlap with the following articles, which were not cited or referenced. Skutella, M., Sviridenko, M., & Uetz, M. (2016). Unrelated Machine Scheduling with Stochastic Processing Times, Mathematics of Operations Research, 41(3), 851–864. https://doi.org/10.1287/moor.2015.0757. Uetz, M. (2003). When greediness fails: examples from stochastic scheduling, Operations Research Letters, 31(6), 413–419. https://doi.org/10.1016/S0167-6377(03)00047-6 Subsequent to investigation, and communication with the authors, we have also been informed by the first corresponding author that the co-authors were not consulted on the decision to submit to the Journal of the Operational Research Society, nor on the submission of the revised manuscript. The first corresponding author also highlighted inaccuracies in the methodology, specifically the omission of the Worker element extension and the improper application of the model’s extension from discrete to continuous time, both of which were important to the claimed contribution of the article. The authors have agreed with the decision to retract the article. We have been informed in our decision-making by our Editorial Policies and the COPE guidelines. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
