Integrated Ontologies in Support of Factory Systems Design

摘要

Digital factory modelling based on virtual design and simulation has emerged as part of the mainstream activities geared towards reducing product design cycle. Some basic industrial systems are currently integrated via semantic modelling technologies so that products matching processes and resource requirements are integrated to fulfil customer demands. Despite these achievements, product design is still dependent on the knowledge of designers and do not benefit from existing process and resource knowledge, which are in separate domains. This paper therefore presents an integration method based on semantic technologies and PPR ontologies to enable the reuse of known and unknown knowledge. The method relies on the use of cloud manufacturing to improve the efficiency of responsesgenerated by querying the PPR ontology.
