基于直觉三角模糊 TOPSIS 的高铁列车调度指挥人因失误风险排序

摘要

针对高速铁路调度指挥人因风险排序问题，从人因失误概率、人因失误探测度、人因失误重要度和事故严酷度四个方面构建风险评价指标体系。考虑到人因风险指标的模糊性和不确定性，用直觉三角模糊数描述各指标值，基于直觉模糊熵计算指标客观权重，然后建立基于TOPSIS法的高铁列车调度指挥人因失误风险排序模型。最后，基于实例验证了排序模型的实用性。%Error probability, error detectability, error importance and accident severity were used to evaluate hu-man error risk .Due to the uncertainties and imprecisions , the risk factors were characterized with intuitionistic tri-angular fuzzy numbers .The objective weights of four factors were calculated based on intuitionistic fuzzy entropy . Then, a risk prioritization model of human error for high-speed railway dispatchers based on intuitionistic triangular fuzzy TOPSIS was constructed .A case example was presented to demonstrate the practicality of proposed approach .
