Abstract

For supporting fault diagnosis of an industrial installation having a plurality of installation components connected via a pipeline system, provision is made for assigning each installation component to one of a plurality of abstract component types, where a weighted directed component graph is in turn assigned to each component type. A piping and instrumentation flow diagram of the industrial installation is processed component by component proceeding from a start point along a pipeline system. Here, in the case of each installation component, the component graph of the installation component assigned according to the component type is accessed. The individual component graphs are joined together to form a system of weighted directed overall graphs of the industrial installation, the nodes of which are each assigned to a plurality of individual installation components.
