weight estimation

The analytic methods include multidimensional diagnostics,noise modulation with blade passage frequency,and calculation of cavitation erosion,which base on the processing of cavitation noise.

本文从数据的测试与存储管理、信号数据的分析、空蚀失重量估计等方面介绍了水轮机空化空蚀软件的设计思路和方法。

To solve these problems, a new AHP method is presented by combining the weight vector rang estimation analytic theory with traditional evaluation index rejecting method.

针对用层次分析法(AHP)进行评价指标筛选过程中经常出现比较矩阵不一致、相对权重值差别较大等问题,将权重向量区间估计分析理论与传统的评价指标剔除方法相结合,提出了一种新的AHP评价指标筛选方法,并以海底管道工程方案评价指标体系的确定为例进行了实际应用,结果表明该方法具有较强的实用性和可操作性。
