摘要
为了提高危险化学品道路运输系统(Dangerous Chemical Road Transport System,DCRTS)风险性评价结果的准确性,避免主观权重的影响,本文基于突变理论,研究并建立了道路"人-物"的尖点突变模型;结合危化品运输的特殊性,构建DCRTS突变安全评价指标体系;采用模糊突变级数评价法获取系统不同时刻的突变值,并进行逐级计算,得到系统总突变隶属函数值.研究表明,基于突变理论的危险化学品道路运输系统评价能科学客观地反映实际情况.
In order to improve the accuracy of Dangerous Chemical Road Transport System( DCRTS) risk assessment results and avoid the influence of subjective weights,based on the catastrophe theory,the cusp catastrophe model of road "human-object " was studied and established,combined with the speciality of transportation of hazardous chemicals,the DCRTS catastrophe safety evaluation index system was constructed.The fuzzy catastrophe progression evaluation method was used to obtain the sudden change values of the system at different times,and the system was calculated step by step to obtain the total catastrophe membership function value. The studies showed that the evaluation of DCRTS based on catastrophe theory can reflect the actual situation scientifically and objectively.
