Method & Evidence

AimTo develop and validate a hybrid decision-making model (Fuzzy AHP and Grey Relational TOPSIS) for assessing and ranking the sustainable development of tourism regions.
MethodHybrid Decision-Making Model (Fuzzy AHP and Grey Relational TOPSIS)
ProcedureEstablished a 13-indicator evaluation system across economic, social, environmental, and cultural dimensions. Utilized Fuzzy AHP to determine indicator weights through fuzzy judgment matrices and consistency tests. Applied Grey Relational TOPSIS, integrating Euclidean distance and grey relational degree, to calculate a hybrid closeness index for ranking regions. Verified the model with data from seven tourist regions.

Strengths & Limitations

Strengths

  • +Addresses ambiguity and subjectivity in indicator weighting.
  • +Integrates multiple evaluation criteria into a single ranking system.
  • +Provides a quantitative basis for decision-making.

Limitations

Data collection for all indicators can be challenging. The complexity of the model might require significant computational resources or specialized software.

Reliability & validity

The reliability of the model depends on the consistency of expert judgments in the Fuzzy AHP phase and the robustness of the Grey Relational TOPSIS calculations. Validity is supported by the logical framework and the application to real-world cases, though external validation with different datasets would strengthen it.

Think critically

How might the cultural context of different tourist regions influence the perception and importance of the 'culture' dimension in sustainable development, and how could this be better accounted for in the evaluation model?

05

Design Principles

"Employ hybrid decision-making models to address ambiguity and subjectivity in evaluating complex systems."

This approach provides a robust framework for evaluating the multifaceted impacts of tourism, enabling informed decision-making for regional development. By quantifying sustainability levels, stakeholders can identify areas for improvement and implement targeted strategies to foster more responsible and resilient tourism practices.
