Performance of fault diagnosis system based on signed directed graph (SDG) is experimentally analyzed. The performance of the system can be evaluated in terms of reliability, accuracy and speed, which are greatly influenced by the thresholds to be used for distinguishing abnormal from normal measurements. To search an optimal adjustment of thresholds is formulated as the maximization of a performance index which is the similarity to the ideal diagnostic result. Finally, we present a guideline on the determination of the thresholds in the application of fault diagnosis system based on SDG to practical chemical plants.
