Super-efficiency based on a modified directional distance function

Chen, Yao; Du, Juan; Huo, Jiazhen - In: Omega 41 (2013) 3, pp. 621-625

The problem of infeasibility arises in conventional radial super-efficiency data envelopment analysis (DEA) models … developed based on a directional distance function. Although this N–L super-efficiency model does not suffer infeasibility …-efficiency model successfully addresses the infeasibility issues occurring either in conventional VRS models or the N–L super …

A slacks-based measure of super-efficiency in data envelopment analysis: An alternative approach

Fang, Hsin-Hsiung; Lee, Hsuan-Shih; Hwang, Shiuh-Nan; … - In: Omega 41 (2013) 4, pp. 731-734

The current paper proposes a slack-based version of the Super SBM, which is an alternative super-efficiency model for the SBM proposed by Tone. Our two-stage approach provides the same super-efficiency score as that obtained by the Super SBM model when the evaluated DMU is efficient and yields...

Carbon Emissions Abatement (CEA) allocation and compensation schemes based on DEA

Feng, Chenpeng; Chu, Feng; Ding, Jingjing; Bi, Gongbing; … - In: Omega 53 (2015) C, pp. 78-89

As environment constraints on economic growth are strengthening, Carbon Emissions Abatement (CEA) allocation becomes a significant issue that draws academia׳s attention. In the literature, the Data Envelopment Analysis (DEA) technique has been applied to obtain CEA allocation with centralized...

Human development and data envelopment analysis: A structured literature review

Mariano, Enzo Barberio; Sobreiro, Vinicius Amorim; … - In: Omega 54 (2015) C, pp. 33-49

Given the importance the concept of productive efficiency has on analyzing the human development process, which is complex and multidimensional, this study conducts a literature review on the research works that have used the data envelopment analysis (DEA) to measure and analyze the development...

Data envelopment analysis: Prior to choosing a model

Cook, Wade D.; Tone, Kaoru; Zhu, Joe - In: Omega 44 (2014) C, pp. 1-4

In this paper, we address several issues related to the use of data envelopment analysis (DEA). These issues include model orientation, input and output selection/definition, the use of mixed and raw data, and the number of inputs and outputs to use versus the number of decision making units...

Efficiency measures of the Chinese commercial banking system using an additive two-stage DEA

Wang, Ke; Huang, Wei; Wu, Jie; Liu, Ying-Nan - In: Omega 44 (2014) C, pp. 5-20

Measuring and improving the efficiency of the Chinese commercial banking system has recently attracted increasing interest. Few studies, however, have adopted the two-stage network DEA to explore this issue in the Chinese context. Because the entire operational process of the banking system...

Efficiency improvement from multiple perspectives: An application to Japanese banking industry

Yang, Xiaopeng; Morita, Hiroshi - In: Omega 41 (2013) 3, pp. 501-509

The current study focuses on efficiency improvement for banking systems from multiple perspectives, which have different definitions of input/output about various attributes of a banking system. In this research we utilize data envelopment analysis (DEA) and Nash bargaining game (NBG) theory to...

Sustainable design performance evaluation with applications in the automobile industry: Focusing on inefficiency by undesirable factors

Hwang, Shiuh-Nan; Chen, Chialin; Chen, Yao; Lee, Hsuan-Shih - In: Omega 41 (2013) 3, pp. 553-558

Design for the environment (DfE) has been recognized as one of the most important practices for achieving sustainability. One major challenge in DfE implementation is how to effectively deal with the mix of the both the desirable outputs (to maintain or improve traditional product attributes)...

DEA models for extended two-stage network structures

Li, Yongjun; Chen, Yao; Liang, Liang; Xie, Jianhui - In: Omega 40 (2012) 5, pp. 611-618

Liang et al. (2008) [1] developed DEA models based upon game approach to decompose efficiency for two-stage network structures where all outputs of the first stage are the only inputs to the second stage. This paper extends Liang et al. (2008) [1] by assuming that the inputs to the second stage...

Non-oriented slack-based decompositions of profit change with an application to Taiwanese banking

Juo, Jia-Ching; Fu, Tsu-Tan; Yu, Ming-Miin - In: Omega 40 (2012) 5, pp. 550-561

A change in profit can originate from the output side and the input side. In the spirit of work by Tone [1] and follows Grifell-Tatjé and Lovell's [2], we propose a non-oriented slacks-based measure (SBM) model to decompose the change in the operating profit into various meaningful components:...
