Design and development of fuzzy systems at Siemens R&D

In the 1980s several Siemens groups inside and outside Germany started activities within the area of fuzzy control and classification. Siemens Corporate Research and Development in Munich decided to start a central research group, to coordinate and support the activities within the groups. This research group had three main assignments, namely (1) to bring Siemens to the state-of-the-art fuzzy control and classification, (2) to develop software tools to support the implementation of fuzzy systems, and (3) to build up a methodology for the design and development of fuzzy systems. The author mainly deals with this third assignment. He shows several aspects of the design and development of fuzzy controllers and exemplifies this process by the defuzzification methodology
