The invention relates to a computer-aided system which is capable of displaying component and process structures for configurable product classes, said product classes being stored in a data structure. Product classes in the data structure are represented by product nodes. Components, which are abstractions of actual items used in the product, are represented by component nodes. Component nodes are mapped onto each product class to which the component is allocated, and are allocated to one or more component variants, these being actual items used in the production of a particular product variant. Process nodes, which are abstractions of actual steps required to produce a product variant, known as process variants, are represented by process nodes. On receiving the selection of a particular product class, the 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 product variant and displays all of the component variants used in the production of this product variant, in the form of lists of materials.
