This study develops a novel mechanism for integrating ontology-based product lifecycle knowledge to effectively integrate the heterogeneous product knowledge distributed among different enterprises during a product’s lifecycle, thereby facilitating sharing of this product knowledge. This study: (i) designed an integration and sharing process for collaborative product lifecycle knowledge, (ii) developed techniques associated with integration of ontology-based product lifecycle knowledge, and (iii) implemented an integration and sharing mechanism for ontology-based product lifecycle knowledge. In developing techniques associated with integration of ontology-based product lifecycle knowledge, which involves establishing a product lifecycle ontology, designing local ontology schema, designing an integration algorithm for ontology-based product lifecycle knowledge, and designing a searching method for ontology-based product lifecycle knowledge.
