Reliability Analysis for Complex Systems Based on Dynamic evidential Network Considering Epistemic Uncertainty

Computer Modeling in Engineering & Sciences 2017年第1期113卷 17-34页

作者： Rongxing Duan Yanni Lin Longfei Hu School of Information Engineering Nanchang UniversityNanchangChina

Fault tolerant technology has greatly improved the reliability of modern systems on one hand and makes their failure mechanisms more complex on the *** characteristics of dynamics of failure,diversity of distribution and epistemic uncertainty always exist in these systems,which increase the challenges in the reliability assessment of these systems *** paper presents a novel reliability analysis framework for complex systems within which the failure rates of components are expressed in interval ***,it uses a dynamic fault tree(DFT)to model the dynamic fault behaviors and copes with the epistemic uncertainty using Dempster-Shafer(D-S)theory and interval ***,an approach is presented to convert a DFT into a dynamic evidential network(DEN)to calculate the reliability ***,a sorting method based on the possibility degree is proposed to rank the importance of components represented by interval numbers in order to obtain the most critical components,which can be used to provide the guidance for system design,maintenance planning and fault ***,a numerical example is provided to illustrate the availability and efficiency of the proposed method.

An Approach for Designing and Implementing Evidence Management Systems

引用

Intelligent Information Management 2010年第10期2卷 613-617页

作者： Dongping Gao Zhendong Niu Baosheng Zhang Nanning Zhang 不详

Generally speaking, the software of management systems in law field is based on the frames of events. However, we are going to study and develop the new software of management system in which the basic elements are evidence. This kind of software is often called evidence management system. Here we are supposed to present a designing plan and an implementing approach for the evidence management system in detail. Some functions such as global, dynamic and systematic managing of evidence can be implemented in this system. We attempt to provide a function of individual searching as well. Users may carry out multi-dimensional data analysis based on the information of our database of the management systems.
