【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。
[Abstract]:In order to evaluate the dam safety monitoring system accurately and reasonably, using extension theory, the extension analysis model of structure element is used to determine the qualitative description of the working state of the monitoring system by using the extensibility of the matter-element. Using the correlation function of extension set to determine the quantitative description of the influence degree of evaluation index on the state of monitoring system, combining quantitative analysis with qualitative analysis, the traditional weight determination generally adopts subjective weighting method, neglecting the influence of objective factors. In this paper, the weight of the index system is determined by the combination of analytic hierarchy process (AHP) and entropy weight method, and the influence of subjective and objective factors is considered synthetically. The example shows that the evaluation results of the model are in accordance with the actual situation. It provides a new idea for dam safety monitoring system evaluation.
