摘要
应急管理系统是多状态系统,适合选用GO法进行可靠性分析。本文建立了应急管理系统GO图,给出了应急管理系统GO图操作符的计算方法,借助梯形模糊数理论将模糊语言转化为数学语言,最终形成了基于GO法的应急管理系统可靠性分析模型。通过实例分析表明GO法对应急管理系统可靠性分析是可行有效的。
Emergency management system is a multistate system,so it is feasible to use GO method to carry out reliability analysis on it.This paper establishes the GO figure for emergency management system,and gives the operators calculation method of GO figure for it.In the case of calculating operators＇ failure rate,trapezoidal fuzzy number theory is used to change fuzzy language into mathematical language.Finally the emergency management system reliability analysis model based on GO method is developed.Through the case analysis,it is proved that the reliability analysis model is feasible and efficient.
