Gozintographs for By-Products and Cyclic Production: An Approach for ERP System Application

Cyclic production, which is distinctive of recycling and chemical processes, and by-products can hardly be managed in common ERP systems. This problem is discussed using graph representations like gozintographs. Furthermore an approach is presented to handle by-products and cyclic production with common gozintograph structures for acceptable solutions in the material requirements planning (MRP). For ERP application appropriated data structures are proposed. A discussion of benefits and limitations of the approach conclude the contribution.
