Abstract:

In order to enhance the scientific rigor and accuracy of street fire safety governance assessment, an improved VIKOR method based on the Choquet integral was proposed. First, an assessment indicator system was constructed from four dimensions: personnel, buildings and facilities, environment, and management. Then, probabilistic hesitant fuzzy sets were introduced to characterize the uncertainty in expert assessments and obtain indicator values. Next, a fuzzy measure was employed to analyze the interactions among indicators, while the Choquet integral and the Shapley value were utilized to aggregate indicator information and dynamically update indicator weights. These procedures were further integrated into the VIKOR decision-making framework. Finally, four streets were selected for empirical validation. The results show that the proposed method systematically considers indicator interactions and their influence on assessment outcomes. In particular, the ranking bias inherent in the traditional VIKOR method is effectively corrected when the degree of indicator interaction is high, significantly improving assessment accuracy. The case study indicates that Street D shows the lowest level of fire safety governance, followed by Street A and Street B, while Street C ranks the highest. This result is consistent with the actual fire accident frequencies, which verifies the reliability of the proposed method.
