CAESAR - an architecture for enterprise modelling in the aec industry
Abstract: This paper reviews work in progress concerning information modelling in support
of enterprise engineering, and discuses how important modelling challenges are
being addressed to support more cost effective development of offshore
installations for oil production in the Norwegian part of the North Sea. The paper
describes a framework and a methodology for information modelling of real
world project enterprises and presents initial application examples from the
offshore oil and gas industry.
CAESAR Offshore is a research program undertaken jointly by Norwegian oil
companies, engineering ms, research institutions and the Norwegian Research
Council, with the aim of utilising information-technology-based methods and tools
which lead to more cost effective field development and operation. As a part of
CAESAR Offshore we are developing an object oriented system architecture
consisting of a framework and methodology for information modelling, based on
our belief that complete and correct enterprise models of development projects
must include both the project requirements, deliverables, activities and
organisation. Thus information models of projects must represent both the
objective, product, process and organisation dimensions.
Based upon a model of engineering design, we explicate and relate the enterprise
dimensions, and outline a way of describing the difference between planned
action and actual behaviour. We implement our model architecture according to
an information meta-model, based on a set of common reference entities, and a
general offshore reference model. In our work we are using the offshore
reference model, as the basis for modelling offshore platforms, design of
hydraulic system for offshore production units, and project control systems for
engineering design projects.
