A Framework for Evolutionary Information Model Development

Large scale information modelling projects, like the development of ISO/STEP, require a modelling approach that does not develop a new model from scratch, but rather base it on a more generic model which, in turn, is based on an even more abstract model, etc. The resulting structure shows a layered framework. On top of which can be found the most generic concepts and downward the more specific concepts with increased semantics. The benefits of such a model development approach are improvements in: version management, object orientated modelling, concurrent model development, controlled change, standardized interfaces, conformance testing etc. This paper describes an environment which supports the development of a new model out of one or more generic parent models. The generation process consists of two steps. In the first step entities of the parent models can be instanciated while constraining the inherited behaviour and introducing new behaviour. In fact this process is identical with instanciating run time objects from class templates in the object oriented paradigm. However, in the authors'development environment an important (inherited) property of each entity is self-reproduction. In the second step, therefore, each instance is forced to represent its run time state into some kind of information modelling language specification. Appropriate measures are taken to guarantee that the resulting model will conform the behaviour of its parent model(s). The paper demonstrates this approach in a multi-layered example currently being implemented and explores several implementation issue

Distributed modeling for road authorities

A great challenge for road authorities is to improve the effectiveness and efficiency of their core processes by improving data exchange and sharing using new technologies such as building information modeling (BIM). BIM has already been successfully implemented in other sectors, such as architecture. But the civil infrastructure sector still lags behind. This paper reports the core findings of the research undertaken in an FP7 project called V-Con, Virtual Construction for Roads. In this EU-funded project, BIM technologies are being implemented at road authorities. Typical interest areas of the road authorities are the programming phase, in which requirements management and systems engineering play a key role, as well as the use and maintenance phase, in which asset management is essential. These processes require special attention in information management for road authorities. Furthermore, road authorities are interested in standardized “as designed” road information. IFC would be a good standard for this, but there is no “IFC for roads” yet. But road authorities are also interested in information about the context of the road, as usually defined in GIS. So GIS should be linked to the envisaged system as well. Finally, it was observed that there is a need in the infrastructure sector for so-called concept libraries, libraries with objects and concepts that can be located and managed on different levels (from project-specific to national and global). It was found that the support of such libraries requires changes in the way information modeling and exchange is commonly approached. The new approach is called “distributed modeling” and will be elaborated in this pape

ICT tools for improving the competitiveness of the LSE industry. Engineering construction and architectural management 1999

This paper describes an analysis of Product Data and Information Technologies (PDIT) which are available to support processes in Large Scale Engineering and construction especially. Three main areas were addressed: Supporting Environment, Systems & Technologies and Application Software. On-going and future developments in these areas are considered
