An ontology-driven framework to support scenario representation in a 3D operator training simulator

This paper presents a framework to support the development of three-dimensional virtual scenarios for an operator training simulator for electrical systems. Given the need to represent a variety of scenarios of interest, this can be an effort and time consuming task. The proposed framework promotes a systematic approach when building scenarios and is supported by tools from the ontology-based domain. An editing tool is also under construction. As it will be discussed in the paper, this approach resulted in the simplification of the scenario building process which is achieved by interchanging descriptions at different levels of abstraction. The descriptions concern the situation to be represented; plant objects' representation, both visual and behavioural, the latter represented as Coloured Petri Nets (CPN) models.
