Research on risk analysis of suspension system in maglev train based on fuzzy multiple attribute decision-making

As a new-type rail transportation tool, the medium and low speed maglev train will assume the arduous task of the urban rail transportation. Whether it can run safely and reliably relates directly to the life and property safety, and meanwhile relates to the sustainable development of the maglev transportation industry. This paper provides the general method fit for the risk analysis of the full life cycle of the maglev train system, and puts forward the method of assessing the risk level in FMEA by utilizing the risk analysis method on basis of the fuzzy multiple attribute decision making theory. The method eliminates the influence of the subjective factors of people and the uncertain factors on the assessment results during the analytic process to a certain extent, and makes the relationship between the corresponding risk priorities of every fault more objective and reasonable.
