Demonstration Schedule 

Only the Deep Inference Subsystem is demonstrated. The experimental results of the whole 
system, which consists of the Deep Inference Subsystem, the Shallow Inference Subsystem and the 
plant simulator, is demonstrated using the video tape. 

Step1) Occurrence of an unforeseen abnormal plant situation 
 
The case of multiple faults is demonstrated below. The video tape reproduces the scene of the 
abnormal plant situation caused by the malfunction of the plant simulator. In this demonstration, 
this occurrence is a manual input into the system.

Step2) Detection of the symptoms 

The Plant Monitor detects the unallowable deviations between the predicted plant behavior and 
the observed one. After that, the Deep Inference Subsystem is activated. 



Step3) Activation of the Diagnosor 

The Diagnosor calculates the possible disorders for the detected symptoms by using the Qualitative 
Causal Model and the symptoms clustering technique. After that, the Diagnosor outputs the plant 
operations to stop the malfunctioning devices.
