The existing data envelopment analysis (DEA) models for measuring the relative efficiencies of a set of decision making units (DMUs) using various inputs to produce various outputs are limited to crisp data. The notion of fuzziness has been introduced to deal with imprecise data. Fuzzy DEA models are made more powerful for applications. This paper develops the measure of efficiencies in input o...

In the case of proportional output reduction strategy with a single output, Variable-Returns-to-Scale (VRS) Zero-Sum Gains Data Envelopment Analysis (ZSG-DEA) efficiency scores can be obtained from VRS conventional DEA by means Target’s Assessment Theorem (TAT). Using TAT as departure point, two relations for computing ZSG-DEA appear in literature. Our objective this note is to compare, contras...

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...

Conventional data envelopment analysis (DEA) models are often extended for constant or variable returns to scale assumptions based on the under-investigated technology. It is assumed that all inputs and outputs real-valued data. However, in many practical applications, proportionality convexity axioms require be modified. This study attempts further expand upon hybrid DEA presence of integer-va...

In this study, the financial performance of 10 logistics companies operating in storage, transport and services sector Turkey is evaluated for years from 2011 to 2017 by using Data Envelopment Analysis (DEA) method. accordance with purpose input variables are selected as total assets, equity number employees whereas output net sales, profit before interest tax amount exports. measuring performa...

Our paper reports on the use of data envelopment analysis (DEA) for the assessment of performance of secondary schools in Malaysia during the implementation of the policy of teaching and learning mathematics and science subjects in the English language (PPSMI). The novelty of our application is that it makes use of the hybrid returns-to-scale (HRS) DEA model. This combines the assumption of con...
