A novel imprecise stochastic process model for time-variant or dynamic uncertainty quantification
文献摘要：
This paper proposes a novel model named as"imprecise stochastic process model"to handle the dynamic uncertainty with insufficient sample information in real-world problems.In the imprecise stochastic process model,the imprecise probabilistic model rather than a precise prob-ability distribution function is employed to characterize the uncertainty at each time point for a time-variant parameter,which provides an effective tool for problems with limited experimental samples.The linear correlation between variables at different time points for imprecise stochastic processes is described by defining the auto-correlation coefficient function and the cross-correlation coefficient function.For the convenience of analysis,this paper gives the definition of the P-box-based imprecise stochastic process and categorizes it into two classes:parameterized and non-parameterized P-box-based imprecise stochastic processes.Besides,a time-variant reliabil-ity analysis approach is developed based on the P-box-based imprecise stochastic process model,through which the interval of dynamic reliability for a structure under uncertain dynamic excita-tions or time-variant factors can be obtained.Finally,the effectiveness of the proposed method is verified by investigating three numerical examples.
