A Layer DEA Model for Measuring and Improving the Efficiency in the Presence of Special Decision Making Units

چکیده
In the evaluation of non-efficient units by Data Envelopment Analysis (DEA) referenced Decision Making Units (DMU’s) have an important role. Unfortunately DMU’s with extra ordinary output can lead to a monopoly in a reference set, the fact called abnormality due to the outliers' data. In this paper, we introduce a DEA model for evaluating DMU’s under this circumstance. The layer model can result in a ranking for DMU’s and obtain an improving strategy leading to a better layer.

متن کاملMeasuring the overall performances of decision-making units in the presence of imprecise data
Data envelopment analysis (DEA) is a method for measuring the relative efficiencies of a set of decision-making units (DMUs) that use multiple inputs to produce multiple outputs. In this paper, we study the measurement of DMU performances in DEA in situations where input and/or output values are given as imprecise data. By imprecise data we mean situations where we only know that the actual val...
متن کاملMeasuring a Dynamic Efficiency Based on MONLP Model under DEA Control
Data envelopment analysis (DEA) is a common technique in measuring the relative efficiency of a set of decision making units (DMUs) with multiple inputs and multiple outputs. Standard DEA models are quite limited models, in the sense that they do not consider a DMU at different times. To resolve this problem, DEA models with dynamic structures have been proposed.In a recent pape...
متن کاملA new non oriented models for calculating the efficiency of decision-making units in the presence of flexible variables
In assessing the relative efficiency of decision-maker units by classical Data Envelopment Analysis (DEA) models, the status of the data is determined from the input or output points of views. In real issues, there are some data whose statuses are debatable. Some decision making units consider them as input to achieve higher efficiency while some other decision making units consider them ...
متن کاملMeasuring the efficiency of Iranian electricity distribution companies, a combined approach to bargaining game with DEA
Many models have been proposed for measuring performance of business agencies up to now. The goal of this research is providing a new approach for evaluation and measurement of efficiencies of national power distribution companies. This approach is provided as a combination of Data Envelopment Analysis (DEA) and Game Theory for evaluation of decision-making units by a large scale of actions. I...
