Abstract: The invention relates to a method and a device for locating a fault in a system. The system includes a set of elements. The elements are connected in a network. Each element is associated with an operational status and a probability of failure. The method according to an embodiment of the invention includes, for each of the elements having a status indicating a malfunction, denoted as a defective element, the creation, from the system topology, of an expression comprising terms corresponding to functional elements connected to said defective element. If several expressions have been created in the preceding step, then merge expressions having at least one term in common. For each expression, delete terms in the expression corresponding to elements having a “healthy” status. Calculate a minimal expression from the preceding expression. Calculate failure probabilities for selected members of the minimal expression based on failure probabilities of the corresponding elements.
