An explanation and quantification of the water-energy-food nexus (WEF-Nexus) is important to advance our understanding of regional resource management, which is presently in its infant stage. Evaluation of the current states, interconnections, and trends of WEF-Nexus, in cities, has largely been ignored due to quantification hurdles and the lack of available data. Based on the interaction of WE...

A primal index of productivity change is introduced which decomposes exactly in three components: technical change, technical efficiency change and average scale economies (radial scale change). The proposed index is invariant to movement along indifference surfaces and it collapses to the Malmquist index if the technology is locally constant returns to scale. It is the best linear approximatio...

This article computes the energy productivity changes of regions in Japan using total-factor frameworks based on data envelopment analysis (DEA). Since the traditional DEA-Malmquist index cannot analyze changes in single-factor productivity changes under the total-factor framework, we apply a new index proposed by Hu and Chang [2009. Total-factor energy productivity growth of regions in China. ...

Vietnam’s textile and garment enterprises make an important contribution to the country with second largest export turnover. The existence development of have a significant influence on socioeconomic Vietnam. Currently, industry is facing difficulties caused by COVID-19 pandemic, along competition from foreign direct investment (FDI) enterprises. Therefore, it imperative for managers assess com...

This paper explores the use of the optimisation procedures in SAS/OR software with application to the measurement of e#ciency and productivity of decision-making units (DMUs) using data envelopment analysis (DEA) techniques. DEA was originally introduced by Charnes et al. [J. Oper. Res. 2 (1978) 429] is a linear programming method for assessing the e#ciency and productivity of DMUs. Over the la...

Data envelopment analysis (DEA) based productivity indexes models are widely applied to evaluate the of decision-making units over a period. This study proposes index for evaluating environmentally sensitive growth while excluding possibility spurious technical regress. innovative has been created by combining directional distance functions, sequential DEA, undesirable data, and concept interva...

The purposed-the main purpose of this study is to look at the development of efficiency and productivity in the military hospital sector of Tehran province, by applying a nonparametric method. Design/methodology/approach- The study applied the nonparametric method to assess the efficiency of military hospitals service in Iran, Tehran, over the period 2013-2016. Utilizing non-parametric me...
