Publishing a new research paper in academic and professional journals is very important to facilitate knowledge sharing among scientists and engineers, researchers and practitioners. Variouse measures and citation scores have been developed to evaluate and rank scientific publications in order to foster the progress of research and real world applications. Recently, Hsieh and Chang reported An assessment of world-wide research productivity in production and operations in International Journal of Production Economics[1]. This report explores the global production and operations management (POM) research performance on papers published in 20 core POM journals in the past half century, which is based on the data of 1959-2008 from Thomson Reuters Web of Science/Knowledge databases.
