Opis:: The study was designed to investigate the relative input of payoffs and probabilities into risk judgment on the basis of the analysis of information search pattern. The modified version of MouselabWeb software (http://www.mouselabweb.org) was used as an investigative tool. The amount, the kind and the order of information accessed by subjects to evaluate risk was collected from ordinary respondents and respondents trained in mathematics and statistics. In the latter group were 75 students and young researchers working at National Aeronautics and Space Administration (NASA). The ordinary subjects were 67 Polish students of social sciences. As expected, the NASA group considered more information than ordinary students and searched for more information about probabilities. However, the ratio of information about payoffs to probabilities was close to 1 in both groups. Moreover, average risk rates were similar in both groups. It was also observed that risk rates were positively related with the amount of information about probabilities considered by subjects.

Tytuł:: The strength of emotions in moral judgment and decision-making under risk

Opis:: The focus of this paper is the role of emotions in judgments and choices associated with moral issues. Study 1 shows that depending on the strength of emotions when making a moral decision, people become sensitive to the severity and the probability of harm that their decisions can bring to others. A possible interpretation is that depending on the strength of emotions, people in their moral judgments choose to be either utilitarian or deontologist. In Study 2, following the priority heuristic model, we found that in situations in which the violation of moral norms does not evoke strong negative emotions, people are sensitive to quantitative risk parameters (probabilities and outcomes), and the decision-making process requires a relatively longer time. In moral situations in which a violation of the moral norm evokes strong emotions, decision-making is based on arguments other than quantitative risk parameters, and the process takes a shorter time.

Tytuł:: A method for estimating propulsion risk of the ship casualty

Opis:: Loss of the propulsion function by a ship is one of the most serious categories of hazardous events in sea transport. In specific external conditions it may lead to a loss of ship and environmental pollution. The consequences of propulsion loss by a ship are events classified by the International Maritime Organization as casualties or incidents. The probabilities of occurrence of the former events in a specific time unit constitute the propulsion risk of a ship. Determination of these probabilities is in practice confronted with difficulties connected with shortage of data. A method for estimating the risk caused by loss of a seagoing ship propulsion function is proposed. The estimation is fully based on the expert judgments. Expert is assumed to be well acquainted with the subject he is expected to formulate his judgment on. Expert should also be capable of formulating his judgment. This is connected with level of his education and the language used in the elicitation process, particularly as regards the parameters the expert is expected to estimate. This may be the language of numerical or linguistic values. Numerical values are better but are more difficult to articulate - also errors in judgments are more likely. To overcome this problem and to obtain a more accurate estimation, this study suggests using an analytic hierarchy process (AHP), which quantifies the subjective judgments and confirms the consistency of collected data. An example of the propulsion risk estimation of container carriers operating on the North Atlantic line allows to assess effectiveness of the method.

Tytuł:: Interval-valued intuitionistic fuzzy failure modes and effect analysis of the system failure risk estimation
Autorzy:: Nguyen, H.
Powiązania:: https://bibliotekanauki.pl/articles/243789.pdf
Data publikacji:: 2017

Tematy:: interval-valued intuitionistic fuzzy sets

system failure risk estimation

Opis:: Among the risk assessment methods, failure modes and effects analysis (FMEA) is a popular, widely used engineering technique in many areas. It can be used to identify and eliminate known or potential failure modes to enhance reliability and safety of complex systems. In practice, risk estimations encounter difficulties connected with shortage of data. In such cases, we have to rely on subjective estimations made by persons with practical knowledge in the field of interest, i.e. experts. However, in some realistic situations, the decision makers might be unable to assign the exact values to the evaluation judgments due to his/her limited knowledge. In other words, there is a certain degree of hesitancy in human cognition and his/her judgment, who may have insufficient knowledge of the problem domain or uncertainty in assigning the evaluation values to the objects considered. In order to deal with ambiguity and uncertainty in the imperfect information, there have been recently proposed many various such theories as fuzzy sets, interval-valued fuzzy sets, type-2 fuzzy sets, hesitant sets, grey sets, rough sets and intuitionistic fuzzy sets. They have drawn more and more attention of scholars and been adopted in many applications This article addresses the Atanassov’s interval-valued intuitionistic fuzzy sets and FMEA methods in the risk estimation of the system failures based on the expert judgments.

Tytuł:: An application of intuitionistic fuzzy analytic hierarchy process in ship system risk estimation

Tematy:: intuitionistic fuzzy sets

Opis:: In this paper, we extend the analytic hierarchy process (AHP) method and the Atanassov’s intuitionistic fuzzy set (IFS) into the intuitionistic fuzzy analytic hierarchy process (IFAHP) with application in ship system risk estimation. In the safety engineering, risk estimation is in practice confronted with difficulties connected with shortage of data. In such cases, we have to rely on subjective estimations made by persons with practical knowledge in the field of interest, i.e. experts. However, in some realistic situations, the decision makers might be reluctant or unable to assign the crisp evaluation values to the comparison judgments due to his/her limited knowledge. In other words, there is a certain degree of hesitancy in human cognition and his judgment. Taking advantages of IFSs in dealing with ambiguity and uncertainty into account, the IFAHP can be used to handle with the subjective preferences of experts, who may have insufficient knowledge of the problem domain or uncertainty in assigning the evaluation values to the objects considered. This paper also develops a new knowledge-based ranking method to derive the priority vector of the hierarchy. An illustrative example of the propulsion risk estimation of container carriers operating on the North Atlantic line is given to show the applicability and effectiveness of the proposed method.
