Research on Continuous/Discrete Hybrid Causality Diagram for Reasoning Model

Based on the characteristics of causality diagram knowledge expression and according to fuzzy logic methodology, a new approach dealing with the continuous cases is presented in this paper, and a complete solution is put forward, which is a mixed reasoning model compatible with continuous and discrete cases. Through testing experiment on the full-size 950MW nuclear power simulator at Beijing Nuclear Power Simulating Training Centrer in Tsing-hua University, the methodology is proved to be valid.
