In data envelopment analyze (DEA) the scale efficiency in the input-oriented CCR model is less than or equal to the scale efficiency in DEA based on the fractional analysis (DEA-R). Also, the scale efficiency in case of multiple inputs and one output and vice versa the scale efficiencies are equal in DEA and DEA-R. In this paper, first, DEA-R model with weight restrictions when there is relativ...

technical and scale efficiencies of cotton farms, in khorasan province, were estimated through the parametric approach during the period 2000-2003. efficiency was estimated through stochastic translog frontier production function based on panel data. results indicated that technical efficiency wa rated as less than scale efficiency. means of technical and scale efficiency were found to be 63 an...

the purpose of this article is the measurement of technical efficiency and returns to scale using data envelopment (dea) approach. in this study, we have measured efficiency quantity and economies of scale for state owned insurance and private companies for 1384-1385 periods. the results reveal that in the dea with the assumption of variable returns to scale, iran, tosee and razi companies have...

water is one of the most important and limited inputs in agricultural productions. the aim of water resources management in agriculture is increasing production performance and raising water use efficiency. to achieve this, in the present research, the water use efficiency of the main agricultural products and farmers of zabol district was studied using data envelopment analysis (dea) in 2011. ...

This paper uses data envelopment analysis (DEA) to examine the technical, pure technical, and scale efficiencies of 12 branches of the agricultural bank in Guilan province, Iran over the period of 2012-2016. The first results indicated that scale inefficiency contributed more to overall technical inefficiency than pure technical inefficiency over the studied period. Results of return to scale r...

introduction: iran's social security organization provides hospital services through direct treatment system (hospitals owned by the organization) and indirect treatment system (purchasing of hospital services and other health care services from other providers). the current research aims to assess technical performance and determine the relationship between activity size and efficiency level o...

from ancient times, governments have laid emphasis – albeit with varying degrees – on large-scale plans and their impact on society and have thus resorted to them. the iranian government is of course no exception; both before and after the 1979 revolution, the different administrations of the country maintained that employing large-scale plans was fruitful and applied them accordingly. although...

In this research, efficiency of Iranian forest and rangeland decision making unit was assessed using non-parametric method. Inputs and outputs determined by field research and with applying a Delphi method the final input and output variables selected. Forty five wood-producing units (forestry plans) in three northern Iranian province were studied using Data Envelopment Analysis. The efficiency...

iran isone of the main pistachiogrowersinthe world. kerman province is the largest grower of pistachio and sirjan is one of the most important pistachio production areas of kerman province. it is important to the study of efficiency status of pistachio growers and improvetheir efficiency and optimum use of resources in the production. the purpose of this study was to determinationtechnical effi...
