摘要: DEA is a well-established, widely used, and powerful analytical resource in the toolbox of OR/MS analyst. It used to assess relative efficiency many, functionally similar, entities. has applications diverse areas including finance banking, education, healthcare. computationally intensive and, as scale grows, this intensity rapidly becomes one limiting factors its utility. In paper, we explore computations DEA. We investigate theory behind schemes, procedures algorithms performing study report on current practices ranging from basic standard advanced sophisticated. Our objective give researchers practitioners an appreciation for computational aspects that will permit them understand performance, problems, complications, limitations, well potential technique.
