Professor Subhash Ray Publishes in European Journal of Operational Research

Professor Subhash Ray’s paper THE TRANSFORMATION FUNCTION, TECHNICAL EFFICIENCY, AND THE CCR RATIO is forthcoming in a special issue of European Journal of Operational Research commemorating the introduction of Data Envelopment Analysis (DEA) into the Operations Research/Management Science literature forty years back by Charnes, Cooper, and Rhodes (CCR). European Journal of Operational Research is a highly rated peer reviewed journal with an impact factor of 3.426 and a 5-year impact factor 0f 3.96.

DEA is a nonparametric method of evaluating productive efficiency without assuming any explicit production, cost, or profit function. It is particularly useful for benchmarking the performance of non-commercial organizations like schools, hospitals, police departments, etc.

Professor Ray has been an active researcher in this area for decades and is internationally recognized for his book Data Envelopment Analysis written from the viewpoint of neoclassical production economics. Published in 2004 by Cambridge University Press, it continues to be a major reference/textbook for serious researchers. In 2016 he received the W.W. Cooper Lifetime Contribution Award from the International DEA Society (iDEAs).
