This conference has been organised tocelebrate the success of DEA on the 40th Anniversary of the publication of the seminal paperon DEA by Charnes, Cooper and Rhodes in the European Journal of Operational Research. Thepaper has spawned a multitude of papers on the theory and application of DEA taking forwardefficiency and productivity analysis in a variety of directions.Aston Business School is one of the largest and most successful Business Schools in Europe.
