A new paradigm for customer-oriented production is presented. A comple
te specification of a product variant is described as a virtual produc
t, a bill of material represented as a data object. This object may be
used as a basis for production management. A tool for creating, modif
ying and processing virtual products is presented, based on a generic
product structure. This tool may act as a means to facilitate handling
of individual customer-specified products in a serial-oriented produc
tion environment.
