Fuzzy comprehensive evaluation method of high-speed railway traction substation risk assessment research
摘要
Abstract
In order to provide a scientific analysis of safe and reliable operation of the high speed railway traction substation, according to the principle and method of risk assessment and combining with four major factors of personal, environment, management and equipment, a hierarchical model was established. By using the theory of fuzzy mathematics, a risk assessment method based on improved fuzzy analytic hierarchy process and entropy weight method was proposed to compute integrated weight vector of the system. Changing from the principle of maximum degree of membership to determine the rank attribution of the system in the past fuzzy evaluation to the scoring mechanism, the integrated weight vector was transformed into fraction value of the system. The risk level of the system was determined according to fraction value with respect to the score value of area. The example results suggest the risk level of the system can be truly reflected by integrated weight, making full use of the risk assessment of original information. Compared to the traditional maximum membership degree principle, the scoring mechanism is more scientific and overcomes some shortages of the maximum membership degree principle. Therefore, it can provide guidance to managers of high speed railway traction substation.关键词
