Measuring the efficiency of decision making units
A nonlinear (nonconvex) programming model provides a new definition of efficiency for use in evaluating activities of not-for-profit entities participating in public programs. A scalar measure of the efficiency of each participating unit is thereby provided, along with methods for objectively determining weights by reference to the observational data for the multiple outputs and multiple inputs...
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...
متن کاملSUGI 27: A SAS(r) Application for Measuring Efficiency and Productivity of Decision Making Units
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 natura...
