Risk Analysis Based on AHP and Fuzzy Comprehensive Evaluation for Maglev Train Bogie

Risk Analysis Based on AHP and Fuzzy Comprehensive Evaluation for Maglev Train Bogie

The maglev bogie is the key subsystem for maglev train security. To ensure life and property security, it is essential to evaluate its risk level before its operation. In this paper, a combinational method of analytic hierarchy process and fuzzy comprehensive evaluation is proposed to assess hazards...
