A fogyasztói preferenciák vizsgálatához alkalmazott eljárás megválasztása még manapság is rendkívül nehéz döntést képvisel a kutatásokban. feltárt preferencia (SP) jellegű adatokon alapuló módszerek használatakor kutatók elsődleges célja az, hogy minél eredményesebben tudják csökkentetni hipotetikus kontextus okozta torzító hatást, mindemellett egyre több információhoz jussanak felmérés résztve...

Abstract Financial institutions use credit rating models to make lending, investing, and risk management decisions. Credit have been developed using a variety of statistical machine learning methods. These methods, however, are data-intensive dependent on assumptions about data distribution. This research offers an integrated fuzzy model address such issues. study proposes reduce problems. The ...

different methods have been proposed for finding the non-negative solution of fully fuzzy linear system (ffls) i.e. fuzzy linear system with fuzzy coefficients involving fuzzy variables. to the best of our knowledge, there is no method in the literature for finding the non-negative solution of a ffls without any restriction on the coefficient matrix. in this paper a new computational method is ...

data envelopment analysis (dea) is a method to measure relative efficiency of a set of decision-making units (dmus) which uses multiple inputs and produces multiple outputs. in the conventional dea, crisp inputs and outputs are fundamentally necessary. but the observed values of inputs and outputs in real-world problems are sometimes imprecise. thus, performance measurement often needs to be do...
