Special Purpose Railways Safety Assessment Based On Fuzzy Comprehensive Evaluation

China's railway transportation to the "fast, heavy weight, high density" rapid development, its security problem of this one major task has become a national railway departments concerned important aspects. The special railway line as the railway network is an important part of, on account of its own characteristics, the existence of hidden troubles of safety factors, so the special railway line to take effective safety evaluation is very important.This paper focus on professional railway line safety this theme, the special railway line safety situation analysis. And the special railway line and road accident analysis system analysis, special railway line safety influence factors, the effective identification of dangerous and harmful factors. And the special railway line safety influence factors to conduct a comprehensive, systematic analysis. According to the principle of establishing the index system and the index selection method, build special railway line safety index system, and the indexes of detailed description and analysis. Use the AHP method to determine the weight of index, and using the method of entropy weight to be amended, built special railway line safety fuzzy comprehensive evaluation model, and in the study of fuzzy comprehensive evaluation, based on the set value statistics theory defines a circular distribution membership function method; finally, to a specific special railway line as an example, applying the fuzzy comprehensive evaluation model to the evaluation method and model of the practical application simulation analysis, it is concluded that the special railway line safety evaluation grade, and put forward to strengthen the special railway line some measures, Used to guide the enterprise to special railway (line) of the safety management...
