An Approach to Simplify the Index Hierarchy Based on Dempster - Shafer Theory

Chuohao Li, Chengming Liu, Tingting Peng
Based on the two concepts, namely, the different importance of index and the relative different importance of index which are presented in the paper, a knowledge engineering method, namely, an approach to simplify the index hierarchy is developed in this paper, through introducing DS theory. The superiority...

Hierarchical Inconsistent Qualitative Knowledge Integration for Quantitative Bayesian Inference

Rui Chang, Wilfried Brauer
We propose a novel framework for performing quantitative Bayesian inference based on qualitative knowledge. Here, we focus on the treatment in case of inconsistent qualitative knowledge. A hierarchical Bayesian model is proposed for integrating inconsistent qualitative knowledge by calculating a prior...

The Combining Rule of Dempster-Shafer Theory for Correlative Evidence

Ping Wang
The thesis puts forward an improvement method for the combining rule of Dempster-Shafer evidence theory based on the correlation between evidences. Different from D-S theory, the correlation coefficient between evidences is introduced; and varies with the evidence fusion. By decreasing the probability...

A BAYESIAN NETWORK APPROACH FOR FAULT-SECTION ESTIMATION

Shu Zhou, Xiaoru Wang, Qingquan Qian
Changes of the network topology of a power system, which are determined by a sequence of operations of breakers, will influence the relationships between relays and protected sections. Further more, the complexity of power systems and the uncertainty of all kinds of information make the relations between...
