conclusions reduction of surplus production factors through comprehensive planning based on the results of the data envelopment analysis can play a major role in cost reduction of hospitals and health sectors. in hospitals with a technical efficiency score of less than one, the original and projected values of inputs were different; resulting in a surplus. hence, these hospitals should reduce t...

Regarding the increase in needs of human societies to agricultural products, increasing water use efficiency can lead to persistent use of limited water resources. Therefore, in this study using Data Envelopment Analysis (DEA), technical, allocative, managerial and economic efficiency and also Optimal level of inputs is surveyed in order to achieve maximum Efficiency in Marvdasht city in 20...

Based on an unbalanced panel of all Bavarian cooperative banks for the years of 1989-97 which includes information on 283 mergers, we analyze motives and cost effects of small-scale mergers in German banking. Estimating a frontier cost function with a timevariable stochastic efficiency term we show that positive scale and scope effects from a merger arise only if the merged unit closes part of ...

This paper applied a non-parametric (Data Envelopment Analysis) method to analyze the efficiency of farmers, discriminate efficient farmers from inefficient ones and to identify wasteful uses of energy in order to optimize the energy inputs for greenhouse cucumber production in Lorestan province of Iran. Data were collected from 27 cucumber producers by using a face-to-face questionnaire.DEA cr...

use of nitrogen fertilizers has contributed much to the remarkable increase in food production that has occurred during the past 50 years. however, environmental and economic challenges due to nitrogen application in agricultural have increased regard to nitrogen use efficiency (nue). studies conducted around the world shows that only half of nitrogen fertilizer inputs is taken up by crops. unf...

One of the most commonly used techniques in aerospace engineering is RANS (Reynolds average Navier–Stokes) approach for calculating transonic compressor flow field, where accuracy computation significantly affected by turbulence model used. In this work, we use SA, SST, k-ɛ, and PAFV developed based on side-biased mean fluctuations velocity strain rate tensor to numerically simulate NASA Rotor ...

BACKGROUND The Government of Ghana has been implementing various health sector reforms (e.g. user fees in public health facilities, decentralization, sector-wide approaches to donor coordination) in a bid to improve efficiency in health care. However, to date, except for the pilot study reported in this paper, no attempt has been made to make an estimate of the efficiency of hospitals and/or he...

BACKGROUND Hospitals represent a significant proportion of health expenditures in Uganda, accounting for about 26 % of total health expenditure. Improving the technical efficiency of hospitals in Uganda can result in large savings which can be devoted to expand access to services and improve quality of care. This paper explores the technical efficiency of referral hospitals in Uganda during the...

The aim of this article is to investigate issues related to technical efficiency and scale of dairy farms in south-western Victoria, Australia. Data envelopment analysis (DEA) is the technique used and is applied to a sample of 59 farms in the 1999-2000 lactating season. The key result is that 51 per cent of the farms are operating at optimal scale, 34 per cent are below and 15 per cent are abo...
