Abstract : The invention relates to a computer-aided system which is capable of displaying component and process structures for configurable roduct classes, said product classes being stored in a data structure. Product classes in the data structure are re resented by roduct nodes. Components, which are abstractions of actual items used in the roduct, are represented by com onen[ nodes. Com onent nodes rare ma ed onto each product class to which the component is allocated, and are allocated to one or more com onent variants, these being actual items used in the production of a articular product variant. Process nodes, which are abstractions of actual ste s required to produce a product variant, known as rocess variants, are re resented by process nodes. On receiving the selection of a particular product class, t e computer- aided system transfers all of the component nodes and process nodes that are allocated to this product class and is able to represent them graphically, for example. Alternatively, the system receives the input of a roduct variant and displays all of the component variants used in the roduction of this product variant, in the form of lists of materials.
