A Recycling-Oriented Product and Production Planning Knowledge Base

The selection of recyclable materials in product design and the process planning for manufacturing and recycling such products were identified as a promising application domain for knowledge base evolution. In [\protect\citeauthoryearBoley et al.1994] a materials knowledge base is discussed as an integral part of a declarative knowledge base for recycling-oriented product and production planning (RPPP). The overall structure of this knowledge base consists of a module representing the materials, a second one representing production and recycling knowledge and a third module containing products that have been manufactured from these materials (see Fig. 2).
