摘要
为准确合理的对大坝安全监测系统进行评价,运用可拓学理论,构造物元可拓分析模型。利用物元的可拓性确定监测系统工作状态的定性描述,利用可拓集的关联函数确定评价指标对监测系统状态影响程度的定量描述,将定量与定性分析相结合;传统权重的确定一般采用主观赋权法,忽略了客观因素的影响,因此本文引入层次分析法(AHP)与熵权法相结合的方法确定指标体系的权重,综合考虑主客观因素的影响。实例表明,该模型评价的结果与实际相符,为大坝安全监测系统评价提供了新思路。
To evaluate dam safety monitoring system accurately and reasonably ,based on the theory of extenics ,this paper makes a matter-element analysis model ,using the matter-element extensibility determines the qualitative description of the status of the moni-toring system .The correlation functions of extension set are used to determine the quantitative description of the influence degree of evaluation index for monitoring system status ,combine quantitative and qualitative analysis .In determining the weight of index ,u-sing the subjective weighting method ,neglecting the influence of objective factors ,this paper introduces the AHP method combined with entropy weight theory to determine the weight of index system .Examples show that ,the evaluation result is consistent with re-ality ,provide a new method for the evaluation of dam safety monitoring systems .
