Professor Edwin Cheng was the Second Most Productive and Influential Author in EJOR

The European Journal of Operational Research (EJOR) was launched in 1977 as the flagship journal of the Association of European Operational Research Societies. To celebrate its 40th anniversary, EJOR published a paper entitled "Forty years of the European Journal of Operational Research: A bibliometric overview", to present a general bibliometric overview of the journal between 1977 and 2016. The study uses VOS viewer software for mapping bibliographic material and analyzes the publication and citation structure of EJOR and the most productive and influential authors, institutions, and countries of the journal.

The study results show that Faculty Dean, Professor Edwin Cheng, in the Department of Logistics and Maritime Studies, was the second "most productive and influential author" contributing to the journal (in terms of both number of articles published and h-index) during the review period. He also has three papers included in the "50 most-cited articles" in EJOR.
