in most of the multi-criteria decision making problems, it is important to have necessary information about relative importance of each criteria. in this group of problems, weights measure the relative importance of preferences of each criteria in comparison with the other decision making criteria. in this research, the nise method has been used for mapping mean-variance efficient frontier. nis...

The suggested approach, FMAA (Fuzzy Multicriteria Acceptability Analysis), assimilates uncertainties/ imprecisions of objective values and subjective judgments within the discrete Multi-Criteria Decision Analysis (MCDA). The presented algorithm for FMAA implementation utilizes fuzzy criterion values and fuzzy weight coefficients based on the use of fuzzy numbers, integral measure to assess the ...

Among the main causes of low productivity at work, absence from work hours and even disability professionals, are the psychological disorders. Which most often manifests as psychotic disorders, mood disorders, anxiety disorders, antisocial personality, multiple personality disorder and substance abuse, causing damage to the person himself, his family and to the productive system in the country ...

this paper will introduce a new method to obtain the order weightsof the ordered weighted averaging (owa) operator. we will first show therelation between fuzzy quantifiers and neat owa operators and then offer anew combination of them. fuzzy quantifiers are applied for soft computingin modeling the optimism degree of the decision maker. in using neat operators,the ordering of the inputs is not...

The paper shows the contribution that two different multiple criteria decision aiding (MCDA) methods could provide in the field of strategic decisions and urban and territorial planning. In particular, the analytic network process and the dominance-based rough set approach have been considered and discussed in the work with reference to their role in supporting such decision-making processes, t...

This paper performs an assessment of 41 agricultural biogas plants located in Austria to determine their relative performance in terms of economic, environmental, and social criteria and corresponding indicators. The comparison of these renewable energy conversion plants is based on two complementary analyses. Data envelopment analysis (DEA) was conducted to provide measures of radial efficienc...

Developments in computer and information technologies continue to give opportunities for designing advanced E-learning systems while entailing objective and technical evaluation methodologies. Design and development of E-learning systems require timeconsuming and labor-intensive processes; therefore any decision about these systems and their analysis needs systematic and structured guidance to ...

We present a new methodology to lead the selection of Multiple Criteria Decision Analysis (MCDA) methods. It is implemented in Methods Selection Software (MCDA-MSS), decision support system that helps analysts answer recurring question science: “Which most suitable method (or subset MCDA methods) should be used for given Decision-Making Problem (DMP)?”. The MCDA-MSS provides guidance decision-m...
