This paper concerns fault diagnosis of industrial plants and complex systems with special interest in fault diagnosis system design. Scope of research connected with using causal graphs to fault diagnosis is presented. Directed graph is used to describe causal relationships between process variables and faults. New method for finding set of model structures based on causal graph is presented. Model structure is understood as an output variable and set of input variables. Algorithm for determining model sensitivity to faults is described. Method for finding possible ability to detect and isolate each fault given calculated set of models is described. Main ideas are explained on simple example.

Artykuł dotyczy zagadnień projektowania systemów diagnostyki procesów przemysłowych z wykorzystaniem grafów przyczynowo-skutkowych. Przedstawiono stan badań dotyczących zastosowania grafów w diagnostyce. Graf przyczynowo-skutkowy jest grafem skierowanym zawierającym wierzchołki reprezentujące zmienne i uszkodzenia oraz krawędzie obrazujące wzajemne oddziaływania. Zaprezentowano metodę znajdowana zbioru struktur wszystkich modeli, które mogą zostać wykorzystane w systemie diagnostycznym. Opisany jest sposób określania wrażliwości modeli na uszkodzenia oraz znajdowania możliwej do uzyskania wykrywalności i rozróżnialności uszkodzeń.
