The SNF project AVISSIMO (Combining aspect-oriented visualization and animated simulation for the validation of partial, semi-formal requirements models) started in fall 2003 and was still going on in 2004.
The first thread in the project deals with the
simulation of semi-formal and partial models: Firstly, we were
developing a concept for the simulation of partial and semi-formal
models. We showed that the simulation of partial models is an
appropriate means for evolving requirements models. The evolution of
requirements models can be achieved by playing through scenarios. The
resulting instance scenarios of this play-through can then be used to
refine the system. A second achievment was the development of a concept
for regression simulation. Regression simulation supports the evolution
by enabling the replay of simulation traces. This can be used to detect
unwanted changes in the behavior of a model during its evolution.
Thirdly, we developed various concepts for handling semi-formal
simulation, this includes beside other things the extraction of formal
elements out of informally described model parts.
The second
thread in the project deals with aspect-orientation: We first did a
state of the art analysis in the field of aspect-orientation and showed
the usefulness of the combination between aspect-oriented modeling and
simulation techniques for the validation of such models. Secondly, we
began to develop and elaborate visualization techniques for the
description of additional modularization dimensions in functional
requirements models (e.g. ADORA), which can be used to describe
crosscutting concerns. Last but not least, we started to define the
weaving rules, the necessary language elements and the constraints
needed as extension in modeling languages for describing these
crosscutting concerns. The research on the visualization of crosscutting
concerns in functional requirements models is still going on.
