Performance assessment of organizations in making strategic decisions for the future is essential. Thus, the efficiency determinations of organizations through planned economic growth in the future system loads are necessary. One of the most important indicators of performance evaluation is measuring efficiency. Banks are one of the most important economic units that provide proper conditions f...
Determining the type of returns to scale (RTS) and identifying stability region for RTS of evaluating unit are appropriate abilities for forecasting the future the unit when its size is changed. This paper aims to introduce RTS sustainability of frontier decision making units (DMUs) in data envelopment analysis (DEA). Based on the importance of RTS in relation to decisions of managers, differen...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...

Objective: The aims of this study were to determine energy efficiency and CO2 use pattern of grape production in Zanjan province, Iran by a non-parametric method of data envelopment analysis (DEA). Methods: Initial data were collected using a face to face questionnaire from 42 orchards in Abhar city of Zanjan province which is one of the most important centers of grape production in ...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
Due to economic importance production of fish farms, in this research, the producers of cold water fish rainbow trout farms in the province in 2017 was evaluated using Super efficiency comprehensive analysis. In this regard, the information required to complete the questionnaire and paddy yield method based on a comprehensive analysis of the results obtained were compared with Super efficiency ...
Learning from high performance projects is crucial for software process improvement. Therefore, we need to identify outstanding projects that may serve as role models. It is common to measure productivity as an indicator of performance. It is vital that productivity measurements deal correctly with variable returns to scale and multivariate data. Software projects generally exhibit variable ret...
We define a combined DEA score to evaluate efficiency in agricultural research. The production model we propose considers efficiency measurements under variable returns to scale for each year in the period 2012–2017. We postulate a first-order autoregressive process in the presence of covariates, to explain efficiency. Powers of the autocorrelation coefficient estimated assuming a dynamic panel...
