Network data envelopment analysis (NDEA), one of the most important branches recent DEA developments, has been developed for examining decision making units (DMUs) a system with complex and internal component divisions. In this study we apply maximin strategy to network at two levels. At individual DMU level, evaluate system’s performance by maximizing minimum divisions efficiencies, which is b...
This research has been done with the aim of identification of effective factors which influence on credit risk and designing model for estimating credit rating of the companies which have borrowed from a commercial bank in the one-year period by using Data Envelopment Analysis and neural network model and comparison of these two models . For this purpose, the necessary sample data on financial ...
Network data envelopment analysis models assess efficiency of decision-making unit and its sections using historical data but fail to measure efficiency of its units and their internal stages in the future. In this paper we aim to measure efficiency of stages of bank branches and obtain efficiency trend of stages during the time, then to estimate their efficiency in the future therefore we can ...
in the data envelopment analysis (dea) the efficiency of the units can be obtained by identifying the degree of the importance of the criteria (inputs-outputs).in dea basic models, challenges are zero and unequal weights of the criteria when decision- making units are evaluated. one of the strategies applied to deal with these problems is using common weights of the each input...
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...
in this paper allocating a fixed resource for producing finite projects in order to obtaining a desired level of efficiency will be discussed. note that it is assumed that a vector of limited sources is at hand. this vector of resources can be contained human resource, budget, equipment, and facilities. in any firm there exist different suggestions from subunits for running...
