the main purpose of this study was to measure the level of technical efficiency of sugar beet producers and determination of factors affecting it. a sample of 144 producers in the main sugar beet growing areas of hamedan, nahavand, malayer and asadabad were selected by two stage cluster sampling method. data were collected through interviews during farming year of 2001-2002.technical efficiency...

in this paper, non parametric data envelopment analysis (dea) was subjected to the energy data of wheat producers in punjab state, india, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. the main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...

this paper is concerned with the estimation of frontier production function to measure the technical efficiency for iranian textile companies during 1995. the objective of this estimation is to investigate if there are any differences in the technical efficiency between the private and public firms as well as the relationship between technical efficiency and size of textile companies in iran. a...

this study was conducted to rank the broiler farms based on buildings, installations and equipment and its effect on production factors. to determine the contribution of each factor in ranking of farms, a multi-criteria decision analysis (saw) was used. data of 108 broilers were recorded in specific forms and the amount of investment per broiler was calculated for individual factors. to calcula...

due to increasing expansion of energy consumption and also the decrease and tendency towardsending fossil energy reserves, the current energy cycle needs to use alternative energy speciallywind energy, because it’s considerably cheaper than other recycling sources. the presentresearch investigates suitable possibility of exploiting wind energy to create wind power stationin soltanieh zone of za...

Data envelopment analysis (DEA) is a method for evaluating the relative efficiency of a set of firms in a production process. Estimation of cost efficiency is one of the branches of performance evaluation. Cost efficiency evaluates the ability of producing current output with minimum available cost. Now let's assume that there are several groups of firms that operate separately and have differe...

Draft animal power (DAP) has been identified as an environmentally friendly technology that is based on renewable energy and encompasses integration of livestock and crop production systems. Draft animal technology provides farmers with a possibility to cheaply access and use manure from the draft animals and farm power needed to apply renewable practices for land intensification. Compared to m...
