摘　　要：针对水闸安全评价体系中存在定性指标多、指标权重无固定标准及专家主观因素等问题,引进基于指标重要性分值和熵权理论相结合的改进层次分析法(AHP),利用中间型柯西分布确定隶属度函数,并结合模糊综合评价理论对水闸指标体系进行安全评价。实例表明,该方法合理、可行且易于操作。Aiming at the problems of qualitative indexes,the index weight without fixed standard,the experts＇subjective factors,improved AHP method based on the index importance value and entropy weight theory is proposed to evaluate the safety of sluice index system.And then intermediate-type Cauchy distribution is used to establish the membership function.Finally,fuzzy comprehensive evaluation theory is adopted to evaluate the safety of sluice index system.The engineering example shows that the proposed evaluation method is reasonable,feasible and easy to implement.
