The directional distance function and measurement of super-efficiency: an application to airlines data
Lovell and Rouse (LR) have recently proposed a modification of the standard DEA model that overcomes the infeasibility problem often encountered in computing super-efficiency. In the LR procedure one appropriately scales up the observed input vector (scale down the output vector) of the relevant superefficient firm thereby usually creating its inefficient surrogate. An alternative procedure pro...
متن کاملMeasurement of prot inefficiency in presence of interval data using the directional distance function
In many applied programs in real-life problems, both physical inputs and outputsare heterogeneous which in this case the ecient cost and income modelcan not apply to evaluate the cost and income of related turnover. So, a measurementbased on the directional value of prot was presented which we havedeveloped it in this paper and have computed it for interval data. In fact, wehave measured the in...
متن کاملAnalyzing the concept of super-efficiency in data envelopment analysis: A directional distance function approach
Based on the framework of the directional distance function, we conduct a systematic analysis on the measurement of super-efficiency in order to achieve two main objectives. Our primary purpose is developing two generalized directional measures of super-efficiency that completely resolve the crucial infeasibility issue, commonly arisen in the traditional super-efficiency measures. The secondary...
متن کاملMeasurement of dynamic efficiency, a directional distance function parametric approach
This research proposes a parametric estimation of the structural dynamic efficiency measures proposed by Silva and Oude Lansink (2009). Overall, technical and allocative efficiency measurements are derived based on a directional distance function and the duality between this function and the optimal value function. The applicability of the parametric proposal is illustrated by assessing dynamic...
متن کاملInput efficiency profiling: An application to airlines
Data envelopment analysis (DEA) can produce results which lack discrimination, one consequence of this is that a large proportion of decision-making units (DMUs) appear to be efficient. In addition, because it is a radial measure of efficiency it assumes that all inputs at a naturally enveloped production unit need to be reduced by the same proportion for efficiency to be achieved. It would see...
