DEA: 45 years on
In the seminal paper, Charnes, Cooper, and Rhodes (European Journal of Operational Research 2, 429-444, 1978) introduced DEA as a linear programming based method for measuring the comparative efficiency of decision making units (DMUs). Since then DEA has seen exponential growth in both theoretical development and applications. Thousands of papers have been published extending the methodology to address numerous aspects of real life problems. Applications though lagging behind theory are nevertheless well established, ranging from the regulation of utilities to the delivery of financial, health, education and other public and private sector services. Following the DEA40 conference at Aston University in 2018, which celebrated the 40th anniversary of the seminal paper on DEA,  we are now organizing the DEA45 conference in 2023 on the 45th Anniversary of that, the most frequently cited paper in Operational Research journals.

Outline of the Conference
The conference will feature: Papers on the latest research in the field;Applications focused tracks including on Regulation, Agriculture, Education, Financial and Health Services;Round table discussions aimed at early career researchers where former or  current Editors of Journals in the field, including the European Journal of Operational Research and the Journal of Productivity Analysis will offer advice on getting published;
