IntroductionFuzzy numbers,or fuzzy subsets of the realline R,are a convenientconceptfor the representa-tion and arithmetic manipulation of imprecise nu-merical quantities[1,2 ] .In applications,the problemof comparison or ranking fuzzy numbers arises nat-urally.For example,in a fuzzy decision- analysiscontext[3 ] ,comparison of fuzzy expected utilitieslooms imminent.Many methods for comparing two or morefuzzy numbers have been suggested in the litera-ture as surveyed in Ref.[4]. Generally,th… 相似文献

Introduction In the areas of every level of probabilistic riskassessment and management in nuclear powerplants,the application of subjective expert' s judg-ments is broadly in demand.The behind reason isprobably thatthe assessmentis usually performed,based on the limited data due to the scarcity of op-erating experience and/or on the incompleteknowledge due to the complexity of phenomenaembedded in severe accidents[1] .In the literature,subjective expert' s judgment is also called expertjud… 相似文献

基于小波变换的混凝土缺陷特征抽取研究 总被引:2,自引:6,他引:2
采用脉冲回波法对混凝土板中的不同类型的模拟缺陷进行检测,实验分别在密实板、剥离板和空洞板上进行,利用小波分析对脉冲回波信号进行处理,小波变换采用Mallat算法和具有紧支集的Daubechies小波,并从反映缺陷特征的小波变换细节信号的极大模中抽取特征向量,用些特征进行缺陷的模式识别,分析结果表明小波变换在混凝土板类结构缺陷探测中具有很大潜力。 相似文献
