Abstract:
omegranate product in Khash city causes this city enjoys a considerable advantage in terms of the production of this product. In this paper the performance of Khash township pomegranate producers was evaluated with a comprehensive analysis of supercharged performance. In this regard, the relevant information to complete the questionnaire in 2015 pomegranate growers in Khash city, were collected based on a comprehensive analysis method and the desired results were compared with analysis ubiquitous super-efficiency. In general, the results showed that the average level of technical efficiency in the model assuming constant returns to scale (CCR method) 0.46% and the mean level of technical efficiency in the model, the variable returns to scale (BCC method) 0.68%. Also pomegranate orchards under different levels of technical efficiency is evident that the major cause of inefficiency in the management of inputs, It is suggested that, with proper management and allocation of inputs used in the vineyards, pomegranate production efficiency can be increased
Machine summary:
46% and the mean level of technical efficiency in the model, the variable returns to scale (BCC method) 0.
This standard units with a predetermined level of function cannot be compared, but it is a criterion for evaluating the performance of decision-making units in the same condition, in this method instead of the frontier production function, the performance of firms that have the highest ratio of output to input, are considered as the boundary.
This performance measure is calculated by the following equation رجوع شود به تصویر صفحه (4) TECRS: technical efficiency obtained from constant returns to scale model.
This method is based on the basic definition of efficiency on the maximum ratio of total output to total inputs and limitations are including the performance of any of the units under study which cannot be more than its importing, The method of calculating the efficiency of DEA was first introduced in 1978 by Cooper and colleagues (Charnes et al.
The efficiency of the method according to the returns can be fixed, variable, increasing and decreasing the scale ratio can be calculated and effectiveness of multi-product mode is also possible.
4. Results and Discussion The first producers of pomegranate were used and the performance index using data envelopment analysis based models, including models with the assumption of constant returns to scale and variable returns to scale, was estimated then scale efficiency was calculated separately.
