Total factor productivity (TFP) is considered a source of economic growth, and as the constraints climate change energy security gradually increase, green total (GTFP) also included in meaning topic. In this study, we combine super-SBM model with GML index include undesirable outputs to measure GTFP 26 manufacturing sub-sectors China from 2004 2017. The results show that sample period, growth r...

Due to the power industry importance in the process of country economic development,studying the efficiency of power plant s is very important. By measuring the efficiency canbe perceived the strength and awareness of different sectors and can improve theirperformance by provide the appropriate solutions. In this paper, power plants was assumedas a decision-making unit that consume gas and gaso...

In the performance evaluation process, using the classic data envelopment analysis (DEA) models, decision making units (DMUs) are considered as black boxes. While in many cases and different applications such as investment funds, banks, insurance companies, etc., DMUs have a network structure. In addition, in many network structures, some of the indicators used to calculate the efficiency...

This paper deals with the problem of optimizing two-stage structure decision making units (DMUs) where the activity and the performance of two-stage DMU in one period effect on its efficiency in the next period. To evaluate such systems the effect of activities in one period on ones in the next term must be considered. To do so, we propose a dynamic DEA approach to measure the performance of su...

Environmental pollution has caused governments to be concerned about energy saving and the reduction of environmental pollution. Some researchers have presented resource allocation models as multi-objective linear programming (MOLP) in order pay more attention reduction. Energy affects both desirable undesirable outputs. In this paper, we argue for inapplicability existing reducing outputs thro...

This article proposes a model for evaluating inefficiency accounting firms’ corporate social responsibility engagement as part of their broader output production activities. The combines the marketable outputs, socially responsible and undesirable outputs into overall measures firm performance using data envelopment approaches. Methodologically, builds on dynamic by-production model, which acco...
