Vortrag von Prof. Holger Giese an der Charles Universität in Prag

Prof. Holger Giese gave an invited seminar talk entitled "Model-Driven Software Engineering of Self-Adaptive Systems". The seminar is organized by the Distributed Systems Research Group of the Charles University in Prague. The talk took place on 16-2-2010.

Abstract

While software is an immaterial object that does not decay with time,
Parnas pointed out that it is in fact aging. Lehman's laws of software
evolution accordingly states that a system that is being used undergoes
continuing adaption or degrades in effectiveness. Consequently, we can
observe that the ability to cost-effectively adapt software has become
one of the most important critical success factors for software
development today.

One particular vision to address this challenge is self-adaptive
software that incorporates the capability to adjust itself to the
changing needs into the software itself. This capability promises at
first to considerably reduce the costs for required administration and
maintenance and to avoid a decline in quality. In addition, future
generation of software systems that interconnect the today more or less
decoupled applications into complex, evolving software landscapes will
require the capability to adapt itself as an important cornerstone as
the software as whole can no longer be engineered at development time.

In this talk we want review why we should look for means to engineer
self-adaptive software systematically and what requirements have to be
fulfilled to achieve the systematic software engineering of
self-adaptive systems. Then, we will look into the particular role of
models for engineering self-adaptive systems and discuss the current
vision for the model-driven software engineering of self-adaptive
systems. Besides the means to build self-adaptive systems with models,
we will also review the role of models for the validation and
verification of such systems.
