Sensitivity and Stability Radius in Data Envelopment Analysis

An investigation of returns to scale in data envelopment analysis

This paper discusses the determination of returns to scale (RTS) in data envelopment analysis (DEA). Three basic RTS methods and their modi®cations are reviewed and the equivalence between these di€erent RTS methods is presented. The e€ect of multiple optimal DEA solutions on the RTS estimation is studied. It is shown that possible alternate optimal solutions only a€ect the estimation of RTS on...

Finding stability regions for preserving efficiency classification of variable returns to scale technology in data envelopment analysis

This paper addresses issue of sensitivity of efficiency classification of variable returns to scale (VRS) technology for enhancing the credibility of data envelopment analysis (DEA) results in practical applications when an additional decision making unit (DMU) needs to be added to the set being considered. It also develops a structured approach to assisting practitioners in making an appropria...
