We have become aware that a review paper [1] recently published in Processes contained a considerable amount of identical text and a similar structure to a previously published review paper [2], although some novel content was presented, including new citations and a section on smart diagnosis. In agreement with the authors, we-the Editor-in-Chief and Publisher-have decided to withdraw the paper. It will thus be declared retracted and marked accordingly for the scientific record.We wish to apologize to readers of the journal, and particularly to the authors of [2].
