With the advent of knowledge economy and virtual R&D models, enterprises get the knowledge not only from themselves but also from others. Distributed case-based reasoning system (DCBRS) plays an important role in virtual R&D by supporting knowledge sharing. This study develops a novel mechanism for ontology-based distributed case-based reasoning using ontology and a proposed multistage algorithm to effectively support knowledge sharing within a virtual R&D environment. Tasks involved in this study are as follows: (i) design an ontology-based distributed case-based reasoning architecture and procedure, (ii) develop techniques related to the ontology-based distributed case-based reasoning, and (iii) implement an ontology-based distributed case-based reasoning mechanism. Developing methods associated with ontology-based distributed case-based reasoning involves the definition and representation of a user query model, definition and representation of a knowledge case model, definition and establishment of a knowledge case index structure, and development of a distributed knowledge case retrieval and knowledge case adaptation methods. Study results will facilitate heterogeneous knowledge sharing among enterprises participating in a virtual R&D.

With companies having multi-location operations and the increasingemphasis on design and manufacturing internationalization , thecoordination of a wide-area electronically - networked product andprocess development team has become one of the fundamental issues of concurrent engineering . It requires the capabilities forcommunication , information and knowledge sharing , management ofproduct and process data , and tracking of development activitiesacross wide-area network. In order to help industry to become internationally competitive,the objective of this research is to development A Framework forConcurrent Net Shape Product and Process Development that empowersvirtual team and tools to collaborate through coordination andconcurrent sharing of product and process knowledge .
