摘要

数据包络分析(DEA)中最吸引人的问题之一是对决策单元(dmu)拥塞的评估，如果某些投入的减少导致某些产出的增加而不会恶化任何其他投入或产出，同样，如果某些投入的增加导致某些产出的减少而不会改善任何其他投入或产出，则会发生拥塞。在DEA文献中，现有的检测dmu拥塞的方法大多采用传统的拥塞定义，并考虑输入和输出只能成比例变化的情况。本研究提出了一种识别被评估单元的每个输入的拥塞情况的方法，当每个单元的输入和输出可以不成比例地变化时。本文以文献报道的中国科学院16个基础研究所2010年数据集为基础，对该方法的潜在应用进行了说明。

A New Method for Recognizing the Input Congestion in Data Envelopment Analysis

: One of the most attractive issues in Data Envelopment Analysis (DEA) is the evaluation of congestion of Decision Making Units (DMUs), which occurs if the decreases in certain inputs lead to increases in certain outputs without worsening any other input or output and equivalently, if the increases in certain inputs lead to decreases in certain outputs without improving any other input or output. Most of the existing approaches for detecting the congestion of DMUs in the literature on DEA employ the traditional definition of congestion and consider the situation in which the inputs and outputs can only change proportionally. This study proposes a method for recognizing the congestion of each input of a selected unit under evaluation for the case when the input and output of the respective unit can change disproportionally. The potential application of the proposed method is illustrated based on a dataset related to 16 institutes of basic research of the Chinese Academy of Sciences (CAS) for the year 2010, which was also reported in the literature.
