Abstract
Accurate evaluation of Metro operational safety state plays critical role in cites stability and public personal safety. Here, we developed a novel fuzzy evaluation method to evaluate Metro operational safety status more scientifically and accurately, and it systematically integrated expert investigation, grading method and fuzzy comprehensive evaluation method based on entropy weight and analytic hierarchy process (AHP).We used a case data to validate Metro operational safety state, and the result shows that our method evaluates Metro operational safety state, and real dealing ability to safety accidents effectively. This method provides an important theoretical reference for the safe operation mode of the Metro.
