The Study Of Fuzzy Comprehensive Evaluation Method About The Special Rail That Based On Hazard And Operability Analysis

At present, the special railway brings great interests to the enterprise and society, but it has brought some serious security incidents too, such as train derailment, train runaway, turnout shouldered out and so on. These accidents make the damage of rolling stock, casualties and goods lost, and so, this bring economic damage and bad influence to company and society.As the further promotion of People-centered policy, enterprise safety consciousness has be strengthen, enterprise to security needs has be improved, so the security of the special railway become one of important content in the study。In order to improve the safe condition of special railway and to effectively control and reduce the traffic accident of the special railway, the most crucial step is safety evaluation for the special railway. Through the Security status detection and analysis of the special railway, we can identify safety deficiencies,and so we can make relevant safety improvement measures. Nowadays, there is so much method to special railway safety evaluation, but most of them are not only having a few limitations but also are qualitative evaluation, so the accuracy of results vulnerable to disturbed by physical condition. Using actual data on qualitative evaluation about the special railway has more convince, so we need a better method which can make quantitative study more systematic on the special railway qualitative evaluation.The study of fuzzy comprehensive evaluation method about the special rail that based on hazard and operability analysis is not only considering the affect of works feature, but also make qualitative evaluation about the works’current situation. Through quantitative way to identify the most dangerous professional railway works the place and dangerous degree, thus preventing accidents reduce casualties and economic losses, and other units to railway private sidings quantitative research on demonstration role.
