METHOD FOR ANALYZING EFFECTS OF OPERATOR ACTIONS IN INDUSTRIAL PLANTS

摘要

The invention relates to the field of processing systems, particularly for industrial plants. The invention discloses a method for determining an interdependency between a plurality of elements in an industrial processing system. The method comprises the steps of:providing a process flow diagram, PFD, of a topology of the processing system;transforming the PFD into a directed graph, wherein each element of the plurality of elements is transformed into a node and each relation between the plurality of elements is transformed into a directed edge;selecting one node of the plurality of nodes as a starting node; andconstructing a subgraph, wherein the subgraph consists of all the nodes that are forward-connected from the starting node, thus showing at least one interdependency between the plurality of elements in the subgraph.
