ABSTRACT
This paper proposes an ontology-based approach to improve the information communication and message exchanges within the PpU system. The PpU system ontology is constructed according to the work flow of the system to fulfill distributed manufacturing functions. To allow the agent ontology to fully utilize the domain knowledge and acquire new domain knowledge, an ontology is constructed for each agent in the MAS. The rest of the paper is organized as follows. The work flow in an agent based on the ontology model is described in Section 2. In Section 3, the ontology for the PpU platform is modeled as a combination of all the agents in the PpU platform. Ontology matching methods between agent ontologies are illustrated in Section 4. In Section 5, conclusion and future work are presented.
