The Evaluation of the Efficiency with Data Envelopment Analysis in case of Missing Values: A Fuzzy Approach
نویسنده
چکیده
The evaluation of productivity of educational units during the last decades has become an important priority for many countries. A current approach considers the schools as production units that use multiple inputs and produce multiple outputs. Data Envelopment Analysis (DEA) is a very effective methodology for the estimation of relative efficiencies in the presence of multiple inputs and outputs. The shortcoming of the requirement of exact data in traditional DEA lately has been confronted by imprecise or fuzzy DEA approaches. In these considerations it is possible to take into account variables of qualitative manner or variables with missing values. In this paper we evaluate the public high schools of the Greater Athens Area (GAA) for the academic year 2002-2003. The problem of missing values, which appeared in some school units, is countered by using the methodology of fuzzy DEA and the a-level sets of fuzzy numbers.

Efficiency Evaluation and Ranking DMUs in the Presence of Interval Data with Stochastic Bounds
On account of the existence of uncertainty, DEA occasionally faces the situation of imprecise data, especially when a set of DMUs include missing data, ordinal data, interval data, stochastic data, or fuzzy data. Therefore, how to evaluate the efficiency of a set of DMUs in interval environments is a problem worth studying. In this paper, we discussed the new method for evaluation and ranking i...

متن کاملPresenting a New Model for Bank’s Supply Chain Performance Evaluating with DEA Solution Approach
Data Envelopment Analysis (DEA) is a method for measuring the efficiency of peer decision making units (DMUs) with multiple inputs and outputs. The traditional DEA treats decision making units under evaluation as black boxes and calculates their efficiencies with first inputs and last outputs. This carries the notion of missing some intermediate measures in the process of changing the inputs to...
متن کاملFuzzy Data Envelopment Analysis Approach for Ranking of Stocks with an Application to Tehran Stock Exchange
The main goal of this paper is to propose a new approach for efficiency measurement and ranking of stocks. Data envelopment analysis (DEA) is one of the popular and applicable techniques that can be used to reach this goal. However, there are always concerns about negative data and uncertainty in financial markets. Since the classical DEA models cannot deal with negative and imprecise values, i...
