Dr. Peter Liggesmeyer, Professor Software Engineering: Dependability at Kaiserslautern University of Technology.
Last year, Software AG formed a Scientific Advisory Board to provide it with a scientific perspective on trends – and potential trends - in technology. In this series of blogs, we highlight each Scientific Advisory Board member’s area of expertise and some of his views for the future.
Today, we feature Dr. Peter Liggesmeyer.
"'Smart ecosystems' are heterogeneous systems that break up old silo solutions for managing business processes (IT systems) and technical processes (embedded systems) and make them usable as an integrated complete solution.
The resulting systems are comprehensive, heterogeneous, and open - and they change autonomously during runtime. People can only intervene and manage these systems to a limited extent, if at all, because they lack an overview and the reaction speed, or because it would not be cost-effective.
The systems must run mostly autonomously and observe quality attributes—e.g., security—in the process. They need to be able to access suitable models as a basis for autonomous decision-making that, due to their dynamic variability, need to be created differently than system models that are on the cutting-edge of technology.
They must be able to be evaluated by the systems themselves during operation, for example to be able to decide whether a new system configuration is secure. In the past, people decided these types of issues during the development of systems. The result was that a suitable configuration could not be changed while running.
Smart ecosystems require comprehensive modeling approaches, especially for autonomous handling of the dynamic aspects. It must be decided which aspects are either stable or important enough to model them fully. Furthermore, the models need to be able to deal with natural uncertainty.
Platforms that ensure interoperability, for example, are increasingly evolving as a solid basis for these types of solutions, such as the ADAMOS IIoT platform or the BaSys4.0 platform for Industry 4.0, which is currently in development in a project headed up by the Fraunhofer Institute for Experimental Software Engineering (IESE) and financed by the German Federal Ministry for Education and Research.
It can be expected that platforms and comprehensive dynamic modeling approaches will play an important role in realizing smart ecosystems in the future."
