Method for providing a list of equipment elements in industrial plants

A method for providing an impact list of affecting equipment elements that affect an industrial sub-process, wherein affecting the industrial sub-process comprises to control or influence otherwise the sub-process' flow of material, of energy, of information, and/or of other aspects, the method comprising the steps of:

• selecting using a controller, in a topology model, the sub-process,
• wherein the sub-process is an equipment element that is a part of an industrial plant or process, and
• wherein the topology model is a graph generated by the controller, whose nodes represent equipment elements and whose edges represent interconnections between the equipment elements;
• traversing the nodes of the topology model using the controller, wherein the traversing starts from the selected sub-process and uses a traversing strategy;
• and
• for each of the at least one equipment elements, if the equipment element affects the industrial sub-process by an affecting degree greater than a first predefined affecting degree, adding the equipment element to the impact list of affecting equipment elements.
