in this paper, different input-oriented ratio-based dea (dea-r-i) models are proposed. by presenting the envelopment-additive-enhanced russell model based on the dea-r-i form, each decision making unit is evaluated and its efficiency score is calculated. also, by presenting the central resource allocation model based on the dea-r-i form, a suitable benchmark for all dmus is proposed by solving ...

introduction: there are various factors that affect manpower efficiency. identification of the most important and influential factors on efficiency is quite essential. analysis of factors affecting manpower efficiency from the viewpoint of clinical and non-clinical faculty members at guilan university of medical sciences in 2011. methods: this descriptive, analytical, cross-sectional study was ...

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...

conclusions better understanding of the effectiveness and efficiency mechanism and having valid evaluation required considering specific theories and points in this field. applying a dynamic approach with considering epidemiological concepts and sophisticated statistical models could improve quality of studies in this field. results from a total of 797 articles, 20 were eligible which among the...

background hospital emergency departments (eds) are as barometers of the health care system. crowded eds threaten delivery of timely care. prolonged ed wait times reduce the quality of care and increase adverse and sometimes irreversible events. objectives the purpose of this study was to determine the patients' waiting time at namazi and shahid faghihi hospitals in shiraz, iran. patients and m...

This paper develops a test for Pareto-elliciency in the local public sector using the analytical result that aggregate property value is maximized at the public output level which satisfies the Samuelson condition for efficiency. By using cross-section data, it is possible to deduce whether a representative community provides its public goods in a property-value-maximizing (and hence efficient)...

Article history: Received 10 October 2012 Received in revised form 14 October 2013 Accepted 23 March 2014 Available online 12 April 2014 We examine how an exogenous improvement in market efficiency, which allows the stock market to obtain more precise information about the firm's intrinsic value, affects the shareholder–manager contracting problem, managerial incentives, and shareholder value. ...

In this paper, we review the efficiency of both manufacturing processes and systems over recent decades and compare nano-materials technologies in this context. To a first approximation, nano-materials processes appear to be about as efficient as semi-conductor processes. That is, their second law efficiencies are of the order 10, while conventional processes are of order 10. However, many of t...
