Self-optimizing concepts and structures in mechanical engineering (only German version available)
The Collaborative Research Centre 614 „Self-optimizing concepts and structures in mechanical engineering” addresses technical systems of tomorrow. It consist of the configuration of system elements with inherent partial intelligence. The systems behavior will be characterized by communication and cooperation of intelligent system elements. Self-optimization allows technical systems with inherent intelligence, that are able to respond independently and flexibl to changing condition states.
The vision of the SFB 614 is a new school for the design of intelligent mechatronic systems. This new school is based on a set of instruments consisting of process models, design methods and tools and practices. The instrument is developed in the interplay with the development of demanding demonstrators, as representative future mechanical engineering products and related industries like the automotive industry and the medical industry.
After an introduction to the active paradigm of self-optimizing eight demonstrators are described by the following pattern: 1) Scenario description, 2) benefit potentials and objectives of self-optimization, 3) realization of the self-optimization process and 4) Summary. This underscores the basis of representative examples of practice that creates significant value and opens up real prospects for engineering and related industries through self-optimization.
We summarize the developed concepts finally. These include process optimization, development methodology and platform (dynamically reconfigurable hardware and real-time operating system)

The instrument is developed in the interplay with the development of demanding demonstrators, as representative future mechanical engineering products and related industries like the automotive industry and the medical industry.
Against this background emerges the challenge of making such systems reliable. We have the chosen term reliability instead of the dependability, because it covers the aspects availability, reliability, security and confidentiality and therefore expresses our concern on the way to the products of tomorrow.
This book is the result of an interdisciplinary cross-project collaboration in the working group "Safety and stability" of the CRC 614. Haves well-presented introduction of the broad topic of reliability and shows by means of sophisticated examples of advanced mechatronics, how to design systems that are complex, strongly influenced by information and communication technology reliable. It clarities, that the active paradigm of self-optimization does not only require greater efforts to achieve reliability, but also opens up new opportunities for increased reliability.
7th International Heinz Nixdorf Symposium
The integration of mechanical engineering and information technology results in extensive potentials. This is expressed by the term “mechatronics”. This term refers to the symbiotic cooperation of mechanics, electronics, control engineering and software technology, in order to improve the behavior of a technical system. Future mechatronical systems encompass subsystems with inherent partial intelligence due to integrated micro processors.
The behavior of the complete system will be characterized by communication and cooperation of intelligent subsystems. From the information technology point of view it is a distributed system of cooperating agents. This establishes fascinating possibilities for the design of mechatronical products of tomorrow. The term Self-optimization characterizes this perspective.
Self-optimization of a technical system is the endogenous adaption of objectives as reaction to changing influences and the resulting autonomous adjustment of parameters or structure and consequently of the system‘s behavior:
Thus Self-optimization is substantially beyond the well-known control and adaptation strategies; Self-optimization enables systems to act with inherent “intelligence”, to react independently and flexibly to changing operation conditions.

Selbstoptimierung im Maschinenbau
Die absehbare Entwicklung der Informations- und Kommunikationstechnik wird Maschinen und Systeme inhärenter Teilintelligenz ermöglichen. Hierfür verwenden wir den Begriff Selbstoptimierung. Selbstoptimierende Systeme reagieren autonom und flexibel auf sich ändernden Umfeldbedingungen. Sie sind lernfähig und optimieren ihr Verhalten im Betrieb. Etwa vierzig Forscherinnen und Forscher haben es sich zur Aufgabe gemacht, zu klären, wie solche Systeme funktionieren und wo sie Nutzen stiften sollen und vor allem wie sie zu entwickeln sind.
The Annual Report of the Heinz Nixdorf Institute
By the end of every legal year, the Heinz Nixdorf Institute publishes its profesionally designed Annual Report on the expired year in german and english. It cconcerns a concise, easy to conseive description of distinguished activities. The Annual Report contains reports of the seven workgroups and the associated workgroups as well as presentations of further activities like the Graduate College or important events.
