the disposal of nuclear wastes is one of the most controversial issues faced by authorities in japan. in this regard, a survey was conducted among 172 university students to analyze the attitude towards the sitting of a nuclear waste repository in the country. the study focused on a number of variables that influenced the perception of risks before the 2011 tohoku earthquake and tsunami. resul...

Researchers often express probabilistic planning problems as Markov decision process models and then maximize the expected total reward. However, it is often rational to maximize the expected utility of the total reward for a given nonlinear utility function, for example, to model attitudes towards risk in high-stake decision situations. In this paper, we give an overview of basic techniques fo...

Consensus reaching processes are applied in group decision making problems to reach a mutual agreement among a group of decision makers before making a common decision. Different consensus models have been developed to facilitate consensus reaching processes. However, new trends bring diverse challenges in group decision making, such as the modelling of different types of information and of lar...

Very often in decision problems with unior multivariate objective, many results depend upon the signs of successive direct or cross derivatives of the utility function at least up to the 4th order. The purpose of the present paper is to provide a new and unified interpretation of these signs. It is based on the observation that decision-makers like to combine assets the return of which are nega...

This research investigates the antecedents of airline travel intention, including effects crisis management, service quality perceptions, and loyalty programs, along with fear coronavirus disease (COVID-19) risk attitude among individuals from different parts world during peak pandemic. Its main objective is to assess how these variables impact passenger intention. Partial least squares structu...

background: according to the high prevalence of cardiovascular diseases (cvd) in developing countries as well as high treatment expenses for patients and health-care systems, cvd prevention in such societies has a great importance. one of the most effective strategies is improvement of knowledge and attitude towards the cvd risk factors. this study aimed to evaluate the knowledge and attitude o...

This paper utilizes nonparametric tests to investigate the following hypotheses: One, that there is no difference in household wealth distributions derived from the Survey of Consumer Finances for three survey years during the 1990s, namely, 1992, 1995, and 1998. Two, that there is consistency between households attitudes to taking financial risk and their financial risk taking behavior. Three ...

To depict the influence of decision makers’ risk psychology on the interval-valued intuitionistic fuzzy multi-criteria decision-making process, this paper proposes a new method based on prospect theory. Considering the risk attitude of the decision maker, we transform interval-valued intuitionistic fuzzy numbers into real numbers via a prospect value function and consequently derive the prospec...

In fields on which decisions need to be taken including health, as we are seeing nowadays in the COVID-19 crisis, decision-makers face multiple criteria and results with a random component. stochastic multicriteria decision-making models, risk attitude of decision maker is relevant factor. Traditionally, shape utility function only element that represents maker’s attitude. The eduction process ...
