Abstract: This paper studies the multiple attribute group decision making problems, in which the decision makers (DMs) have multiplicative preference information on alternatives. We first make the decision information uniform by using a transformation formula and introduce some linear deviation elements, and then establish a constrained optimization model. Based the model, an approach is develo...

In practical linguistic multi-criteria group decision-making (MCGDM) problems, words may indicate different meanings for various decision makers (DMs), and a high level of consensus indicates that most the members are satisfied with final solution. This study aims at developing novel framework considers personalized individual semantics (PISs) DMs to tackle single-valued neutrosophic MCGDM prob...

This paper proposes a fuzzy multi -criteria decision making method for disaster risk analysis. It considers the application of “α-cut” and “fuzzy arithmetic operations” to rank the fuzzy numbers describing linguistic variables. This article studies the use of variable fuzzy sets and is applied to study disaster area of Nagapattinam district under northeast monsoon rainfall. The relative and syn...

The evaluation of Information Systems (IS) is a critical process for the successful development of any organizational IT capability. An important class of decision making techniques used in practice is based on conflicting criteria applied to the available alternatives, and the results are consolidated into a single ranking. In this process it is often the case that investment alternatives rece...

This paper describes a theory of rational emulation and deviance. It assumes that individuals care about relative position (or ‘status’), and constructs a model of decisionmaking in social and economic settings. The analysis shows why individuals who want to be different from others will, paradoxically, find it rational to imitate other people. The paper also provides a choice-theoretic foundat...

Weighted aggregation of fuzzy preference relations on the set of alternatives by several criteria in decision-making problems is considered. Pairwise comparisons with respect to importance of the criteria are given in fuzzy preference relation as well. The aggregation procedure uses the composition between each two relations of the alternatives. The membership function of the newly constructed ...

This paper presents a new, nonlinear, multicriteria, decision-making method: the characteristic objects (COMET). This approach, which can be characterized as a fuzzy reference model, determines a measurement standard for decision-making problems. This model is distinguished by a constant set of specially chosen characteristic objects that are independent of the alternatives. After identifying a...

Despite the fact that conceptual models of individual decision making under risk are deterministic, attempts to econometrically estimate risk preferences require some assumption about the stochastic nature of choice. Unfortunately, the consequences of making different assumptions are, at present, unclear. In this paper, we compare three popular error specifications (Fechner, contextual utility,...
