Analysis of shipbuilding fabrication process with enterprise ontology

This paper describes the analysis and evaluation of shipbuilding process based on an enterprise ontology. Shipbuilding process is composed of steel fabrication, assembly, erection, launching, sea trials, naming, and delivery. Among them, the fabrication process has been analyzed and evaluated in this study. An enterprise ontology is a cognitive model containing knowledge unique to the enterprise, and enables the representation and sharing of the enterprise’s process knowledge. We have built an enterprise ontology, and represented the shipbuilding process using plug-ins of Protégé. In addition, we have analyzed the current state of the process and dependency among the workflow elements using a Prolog inference engine, and evaluated the shipbuilding process.
