Measures University Libraries Efficiency of Changsha Region using DEA

摘要

Data envelopment analysis (DEA) allows individual decision-making unit (DMU) to select the weights that are most favorable to them in calculating the ratio of the aggregated output to the aggregated input.In this paper we use data envelopment analysis (DEA) to measure the efficiency of the 10 university libraries in Changsha region.The sensitivity of DEA efficiency to various input-output variable combinations is investigated.More university libraries show up efficient when several inputs and output are taken into account.
