This work studies potential ways of integration of two different techniques for fault detection, isolation, and identification in complex dynamic systems: the Lydia NG suite of diagnosis algorithms and the Consistency-based Diagnosis with Possible Conflicts approach. By integrating both techniques, Lydia NG will benefit from a more efficient fault detection and isolation task, and Possible Conflicts will benefit from the identification capabilities of Lydia NG. In this paper, we define a common framework that integrates both techniques, and then we apply the proposed integrated approach to a three-tank system case study, and draw some conclusions about potential ways of integration.
