The approach outlined here wants to illustrate how ontologies [Gr93] could help to support the integration process. The main benefits for an ontology-based approach are the ability to picture all occurring data structures, for ontologies can be seen as nowadays most advanced knowledge representation model the combination of deduction and relational database systems, which extends the mapping and business logic capabilities a higher degree of abstraction, as the model is separated from the data storage its extendibility and reusability

Work undertaken in the context of the ARCHON project has provided a number of important insights into these issues. By providing an in depth analysis of ARCHON's electricity transportation management application, this paper draws together many of the experiences obtained when building one of the world's first operational DA! systems.

It devised a general-purpose architecture, software framework, and methodology which has been used to support the development of DAI systems in a number of real world industrial domains. Two of these applications, electricity transportation management and particle accelerator control, have been run successfully on-line in the organisation for which they were developed (respectively, Iberdrola an electricity utility in the north of Spain and CERN the European Centre for high energy physics research near Geneva). This paper recounts the problems, insights and experiences gained whilst deploying ARCHON technology in these real-world industrial applications. Firstly, it gives the rationale for a DAI approach to industrial applications and highlights the key design forces which shape work in this important domain. Secon...

The integration of market management together with the physical management of the electrical network creates several problems that the use of ICTs is going to help to solve. In this context, Internet and the Semantic Web1 technologies appear as the most cost effective and promising way to achieve the interoperation of both interrelated worlds. Scada is the basic system for every process control. The data provided by the Scada system is mainly focused onto the control o...

As a technique for overcoming this complexity barrier, researchers have started to build systems composed of multiple ...

The notion of `ontology', rooted in philosophy, is used in knowledge engineering to describe explicit specifications of conceptualizations, where a conceptualization is a set of definitions of elements in a domain. It is a useful notion in knowledge based systems development because it provides the means for describing explicitly the conceptualization behind the knowledge represented in a knowledge base. An ontology, in this case for fault diagnosis, is a combination of small-scale ontologies. After a detailed analysis of the network and its behaviour, five viewpoints were identified as relevant for diagnosis. We generated an ontology for each to characterize more accurately and clearly the elements involved in the problem. Each of them focuses on different relevant aspects of the network and has a compact body of knowledge and a clear meaning in the problem. They are identified as transport, control, events, alarms, and trips. Each is discussed by the authors in relation to fault diagnosis

The World Wide Web has appeared as the vehicle to share information and facilitate businesses like the provision of simple configuration capabilities to users. Ontologies have gained acceptance within the research community as the way to make applications interoperable and drive the next intelligent generation of the World Wide Web known as the Semantic Web that many consider as a future enabler of future advance forms of collaborative e-business. It is just this consideration what has motivated the OBELIX * consortium to do research on multi-component product configuration, since collaborative design scenarios over the (Semantic) Web will become a future reality, but have not been researched in depth yet. This paper describes the efforts done and the results obtained in that direction.

The S-TEN technology is extending the Semantic Web technologies for applications in industrial sectors. In the field of active distribution networks several objectives are addressed: to enable an automatic re-configuration of a microgrid, to improve the integration of dispersed generation by enhanced monitoring and control processes and to facilitate the integration of demand resources into the control of the grid using market mechanisms. The grids of the electrical network of the future will need to be highly automated, will require a reduced human intervention and will have a dynamic characteristic. Dynamic characteristic indicates the possibility of the equipment connected in the network to connect, disconnect and provide services to the central controller for managing the network. This capability will require plug and play capabilities that need the specification of standard protocols and data exchange models. But apart from 21, rue d'Artois, F-75008 PARIS

For three years thirteen partners from seven European countries worked on this project which was finally completed by the end of September 1999. This paper presents the innovative concepts developed for ElectroNet. Finally an outlook of a subsequent planned project EPSIM is given.
