论文统计软件。CCR模型是DEA模型中的一种，是数据包络模型中的一种。1978年，著名运筹学家、美国德克萨斯大学教授A.Charnes及W.W.Cooper和E.Rhodes发表了一篇重要论文得出。BCC模型是评价技术效率的一种模型。相对效率是说DEA模型中的DEA有效是相对有效，即相对其他同类的DMU单元而言有效，并不是真正的技术有效和规模有效。
Paper statistics software. CCR model is a kind of DEA model and a kind of data envelope model. In 1978, a famous operational research scientist, professor A. Charnes and W. W. Cooper and E. Rhodes of the University of Texas published an important paper. BCC model is a model for evaluating technical efficiency. Relative efficiency means that DEA efficiency in DEA model is relatively effective, that is to say, it is effective compared with other similar DMU units, but not true technology efficiency and scale efficiency.
