This paper measures the technical efficiency, super-efficiency, slacks, and input/output targets for large Indian pharmaceutical firms according to ownership by applying Data Envelopment Analysis (DEA) approach. The paper uses raw material, salaries & wages, advertisement & marketing and capital usage cost as input variables and net sales revenue as output variable. The super-efficiency model i...

With accelerated urbanisation, continued growth in water demand and the external pressure of from South–North Water Transfer Project, agricultural use Jiangsu is facing a critical situation. Therefore, it important to explore spatial temporal variation efficiency order clarify pathway for improving efficiency. Firstly, Super-Slacks-Based Measure (SBM) model was utilized measure Province, China,...

A new approach or model to the dynamic DEA, referred to as the adjusted dynamic DEA, is proposed in this study. Adjusted dynamic DEA optimizes the production activity of DMUs by introducing adjustment variables to modify the interconnecting activities between consecutive terms, solving conflicts that arise between terms and between management and shareholders. The non-oriented SBM model is used...

As a measure to promote the reform of China’s ecological civilization system, energy-consuming right trading policy has great potential reduce pollutant emissions and achieve green development in China. Based on panel data 254 cities China from 2005 2019, this paper uses difference-in-differences (DID) model super-efficiency slacks-based (Super-SBM) investigate impact efficiency urban developme...

Vehicle industry has made great contribution to human progress. However, in the process of vehicle operation, a large number carbon compounds are emitted, which brings serious environmental problems. As one important means emission governance, development new energy vehicles (NEVs) attracted much attention. The behavior and performance NEV enterprises highly concerned. Using Chinese 23 enterpri...

Supply chain performance evaluation problems are complex problems with multiple criteria and multi-layered internal linking activities. Data Envelopment Analysis (DEA) has been used to evaluate the relative performance of organizational units called Decision Making Units (DMUs). However, the conventional DEA models cannot take into account the complex nature of supply chains with internal linki...

Abstract This paper deals with an inverse data envelopment analysis (DEA) based on the non-radial slacks-based model in presence of uncertainty employing both integer and continuous interval data. To this matter, suitable technology formulation for DEA are proposed using arithmetic partial orders numbers. The is discussed from following question: if output $$DMU_o$$ <mml:math xmlns:mml="http://...

We propose an evaluation approach for a novel travel demand management strategy known as the downtown space reservation system (DSRS). This approach takes into account three perspectives, i.e., transportation service provider’s, the user’s, and the community’s and is based on network-Data Envelopment Analysis (DEA) where the perspectives are inter-related through intermediate inputs/outputs. Tw...

In the prior literature onmeasuring the efficiency of two-stage processes, there are both radial and non-radial methods of efficiency measurement. In some cases, non-radial methods which allow all inputs, intermediate measures and outputs to change non-proportionally are more appropriate than radial methods, but they do not ensure stage efficiency or allow for the efficiency decomposition of tw...

In this letter, we explore the idea of modeling slack variables in support vector machine (SVM) approaches. The study is motivated by SVM+, which models the slacks through a smooth correcting function that is determined by additional (privileged) information about the training examples not available in the test phase. We take a closer look at the meaning and consequences of smooth modeling of s...
