紧急救援系统可靠性评价指标及评价方法研究

基于人机工效学的原理,分析高速公路紧急救援系统的结构组成和特点,从事件检测、救援方案及设备管理3个方面建立紧急救援系统可靠性的评价指标体系,通过理论分析和专家咨询,确定各影响因素的重要度,运用层次分析法与模糊综合评价相结合的方法,对紧急救援系统的可靠性进行评价。采用该方法对陕西省某高速公路紧急救援系统的可靠性进行评价,得到综合评价值为77.96,与实际状况相符,表明该方法可行。

Reliability Evaluation of Emergency Rescue System on Freeway

Based on the ergonomics principles,this paper analyzes the structure and characteristics of emergency rescue system on freeway,and constructs the index system for reliability evaluation of emergency rescue system from incident detection,rescue plans and equipment management.Through theoretical analysis and expert consultation,the importance degree of each influence factor is determined,and the reliability evaluation of emergency rescue system is realized by using AHP(analytic hierarchy process) and fuzzy comprehensive evaluation method.Finally,an application example in Shanxi Province is given,which demonstrates that the evaluation method is feasible.
