Summary
This study introduces a new model integrating intuitionistic fuzzy sets and set pair analysis to assess airport operational risks. The model effectively ranks airport risks by considering expert opinions and uncertain factors.
Area of Science:
- Operations Research
- Decision Science
- Risk Management
Background:
- Airport operational risk assessment is complex due to uncertain indicators.
- Existing methods often lack systematic data and quantitative analysis for these uncertainties.
Purpose of the Study:
- To develop a novel group decision-making model for evaluating airport operational risk.
- To integrate intuitionistic fuzzy sets and set pair analysis for handling uncertainty.
- To provide a tool for transit authorities to rank airport operational risks.
Main Methods:
- Utilized intuitionistic fuzzy sets to characterize uncertain indicators.
- Applied set pair analysis to convert indicators into ternary connection numbers.
- Developed a new distance metric based on intuitionistic fuzzy set and set pair analysis to measure expert consistency.
- Determined the ranking degree of expert groups on airport operational risk.
Main Results:
- The proposed model effectively integrates expert viewpoints and uncertainty factors.
- A case study of four Chinese airports demonstrated varying risk changes with increased contact degree.
- The model identified specific risk trends for Beijing, Tianjin, Qinhuangdao, and Shijiazhuang airports.
Conclusions:
- The integrated model offers an effective tool for ranking airport operational risks.
- It addresses viewpoint deviations and uncertainty factors in group decision-making.
- The findings provide insights into managing and mitigating airport operational risks.

The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...
