XU Rui-hua, Jia Gao, Jiang Zhibin · 2010
To investigate the safety of urban mass transit, the forewarning grade of emergency is evaluated with the fuzzy sets theory. The new fuzzy evaluation method shows how the interrupt time, casualties, happen position, property loss and sphere of influence affect the forewarning grade of emergency in urban mass transit system. The results demonstrate that fuzzy evaluation not only fulfill the comprehensive safety assessment of emergency in urban mass transit, but also catch the emphases in different situations.
