摘要

．我们提出了两种不同网络DEA (NDEA)模型的有效边界的二维表示。这两种表示都遵循先前的研究，该研究使用一种新的线性化形式，对经典DEA的二维表示方法进行了推广。有效边界的图形化表示使不熟悉线性规划和DEA的管理者和决策者能够简单明了地理解所得到的结果。在本研究中，我们可以获得提供每个DMU效率信息的图表。此外，对于采用效率分解方法的NDEA，可以获得一个图来评估每个阶段的技术效率，以及总体效率。基于效率构成的NDEA模型只产生一张图。然而，这种独特的表示在同一个图中显示了阶段级和整个过程级信息。

TWO-DIMENSIONAL REPRESENTATION FOR TWO-STAGE NETWORK DEA MODELS

. We propose two-dimensional representations for the efﬁcient frontier for two different Network DEA (NDEA) models. Both representations follow a previous study that developed a generalization of the two-dimensional representation method for the classic DEA using a new form of linearization. The graphical representation of the efﬁcient frontier allows managers and decision-makers unfamiliar with linear programming and DEA to understand the results obtained simply and clearly. In this study, we can obtain graphs that provide information about the efﬁciencies of each DMU. Furthermore, for the NDEA with an efﬁciency decomposition approach, it is possible to obtain a graph to evaluate the technical efﬁciency for each stage, as well as for the overall efﬁciency. The NDEA model based on efﬁciency composition only produces one graph. However, this unique representation shows the stage-level and the overall process level information within the same graph.
