An ontological approach for planning and scheduling in primary steel production

Effective integration between manufacturing execution systems and business and logistics systems has been of great interest for a long time. Essential part in enterprise integration is the task of optimal planning and scheduling. An ontological approach consisting of integrated ontologies: a core meta-ontology, according to ANSI/ISA S95 standard and different domain specific ontologies for the primary steelmaking is proposed. For the purposes of planning and scheduling the integration between the core meta-ontology and a hot strip mill domain ontology is achieved and a case study is presented. Web Ontology Language (OWL) and Protege as an editor and knowledge acquisition tool are used.
