SUGI 27: A SAS(r) Application for Measuring Efficiency and Productivity of Decision Making Units
نویسنده
چکیده
In the last two decades many authors have developed techniques to measure the efficiency of Decision Making Units in a way consistent with the underlying economic theory of optimization behavior. The model frequently used is Data Envelopment Analysis (DEA) which initially developed by Charnes, Cooper and Rhodes (1978). Using such as efficiency method over two consecutive periods, one can naturally define productivity of Decision Making Units. The aim of this paper is to present the capability of SAS® and SAS/OR® to implement such models. Therefor, the paper provides SAS code for various productivity measures using optimization procedures such as PROC LP. The code can be used to calculate non-parametric Malmquist Index as a base measure for productivity.

Ranking Network-Structured Decision-Making Units and Its Application in Bank Branches
Data envelopment analysis (DEA) is a method used for measuring the efficiency of decision-making units. Unlike the standard models, which assume decision-making units to be a black box, network data envelopment analysis focuses on the internal structure of these units. Some researchers have developed a two-stage method where all the inputs are entirely used in the first stage, producin...
متن کاملA Layer DEA Model for Measuring and Improving the Efficiency in the Presence of Special Decision Making Units
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 resul...

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...
