N2 - A fault diagnosis algorithm using a signed digraph as a model of a system is useful to real-time diagnosis of failures that occur in a chemical plant. It has been improved so much that it can find multiple origins of failures that occur in the plant at the same time. It is imperative that the diagnosis system be evaluated in the design phase of the system in advance for its practical use. In this paper, an accuracy of diagnostic results using the algorithm for multiple origins has been examined by its application to data obtained by the simulation of tank pipeline systems. The accuracy of diagnosis has been evaluated properly by the size of the greatest set of candidates.
