Abstract:
A digital data processing apparatus for manufacturing process control includes input elements for inputting digital signals representative resource elements consumed in a manufacturing process, resource elements produced by the manufacturing process and manufacturing relations between at least one consumed resource and a set of one or more produced resources. These manufacturing relations include at least one of an operational relation, a planning relation, and a financial relation. A production modeling element generates and stores a production model representative of the manufacturing relations. The modeling element includes a sub-element for generating digital signals representing manufacturing one-to-one, one-to-many, many-to-one, and many-to-many relations between consumed and produced resource elements.
