Abstract. Current standard models have improved interoperability in Product Lifecycle Management. But the increase of constrains surrounding information management in an industrial context, and notably for power plant design, like the increase of data, actors, systems and the need of automation and collaboration leads to an increasing use of ontologybased models. However, the design of power plants presents a specific issue, which is rules expression and validation. This need of rules is generated by safety, interoperability or collaboration constrains. The Semantic Web Rule Language (SWRL) is an ontological language based on OWL-DL that allows in addition rules expression. This paper presents SWRL rules and their industrial applications but also limits of this language in PLM applications. It proposes in consequence other rules languages.
The level of efficiency achieved in the diffusion of knowledge within an organisation is acknowledged to be a competitive advantage. As a result, various means have emerged to help share this knowledge. Among the various existing solutions, the use of parameterised files consistently encapsulating data of a refined level of granularity (e.g. figures, words, etc.) is a well-known practice. However, these files-which we will call Parameterised Knowledge Objects (PKOs)-often exhibit redundancy. This has led to a need for mapping, a fastidious work with no added value, which slows down the product redesign process. The goal of this article is to propose a conceptual model for the implementation of an automated tool to manage exchanges between these PKOs. The implementable nature of the model was validated by the development of a demonstrator, tested on an application provided by our industrial partner-the Renault Powertrain Technology Design Department.
Abstract. In the nuclear industry, achieving Long Term Data Preservation is a requirement for nuclear power plants to be safely built, operated over five or six decades and retired. Among them, CAD data suffers from some strong dependencies on the software vendors and its data model thus leading to a possible weakness in the preservation workflow. This paper presents a modeling language, suitable for the 3D representation of a process plant layout, based upon a procedural Constructive Solide Geometry (CSG) approach. The language execution, as well as the layout rendering and exchange, are experimented using a platform independent implementation, based on free software and open standards.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
