Herausforderung Informationsgesellschaft : die Aus- und Weiterbildung von IT-Fachkräften vor einer konzeptionellen Neuorientierung (The challenge of the information society : Conceptual re-orientation in the basic training and continuing education of information technology specialists)

"The creation of an 'information society' is regarded as the central challenge to the future phase of development in Europe. Implementing it represents a profound change in the working life and occupational situation of many employees, thc necessity for reformulating existing occupational descriptions as well as career orientation guidelines is becoming apparent. This is especially true for information technology (IT) specialists; they must be accorded a key role in the creation of the information society. Ever since computers began to be used for commercial applications, IT specialists have been responsible primarily for setting up and operating isolated EDP systems, which to a large extent were restricted to automatic routine tasks. Up until now these tasks have provided the basis for the occupational profile of a technician in this occupational group. However, in the last few years the traditional 'EDP system' has increasingly expandet into integrated information systems crossing organizational lines and tasks within firms; through the networking of partial systems they now span an ever increasing range of tasks and increasingly more complex unstructured job areas. Hence, ever more firms are linking information technological innovations with organisational tasks and demands on job design. The resulting erosion of traditional skilted tasks requires that the qualifications of IT specialists be redefined; their occupational profile must undergo fundamental change. The forms of applying the computer in information technology the closeness to job design and the trend to new more cooperative forms of work should be included in the standards for professional competence and the occupational identity of this group, so that it can maintain its areas of responsibility in the social work process as well as expand them for purposes of future job security. This development poses a dilemma for the training system. Owing to the fact that the basic training and continuing education institutions in the IT area traditionally exhibit a reactive attitude towards the requirements of the market and interpret all changes from the conventional standpoint of the IT specialists as a technician, they are less and less in a position to confront the increasing dynamisation of the innovation processes and the erosion of the traditional skilled tasks in the occupational field of the IT specialist. This situation demands that the inadequate reactive attitude be replaced by a more active attitude towards the market. However, this calls for conceptual clarity and an adequate interpretation scheme for the changing trends. Two central requirements ,ust thus be fulfilled in reorienting the basic training and continuing education system of IT specialists during the transition to the information society: a) The institutions must reposition themselves in their relationship to the market: Instead of taking the traditionally reactive stance they should adopt a proactive stance towards changes in the market. It is of fundamental importance for them to intensify cooperative links to the scientific community as well as to practical information sciences within the framework of a functioning network. b) Basic training and continuing education institutions need a new type of interpretation scheme for analysing changes in qualifications as well as a corresponding model for qualifications: the paradigma of the IT specialist as a technician systematically annuls essential changes in qualifications. The authors suggest an alternative model of 'holistic job design competence', which focusses and reflects on changes in the traditional skilled tasks in the occupational field as influenced by essential development trends. This new model allows basic training and continuing education institutions to adequately reflect the changes in qualifications for the IT specialists in the transition to the information society and to apply the training concepts suitably for future needs."

In-situ-Fabrikation

Die technischen Anforderungen zukünftiger Bauprozesse werden immer komplexer und erfordern maßgeschneiderte Lösungen. Computergesteuerte Produktionsmethoden ermöglichen die Herstellung individuell gestalteter Bauteile ohne erhöhten Kosten- und Zeitaufwand. Im Gegensatz zu stationären Maschinen können mobile Einheiten direkt auf einer bestehenden Baustelle eingesetzt werden und die Leistungsfähigkeit digital beschriebener Elemente produktiv mit einer In-situ-Bauweise vereinen. Der direkte Einsatz von Industrierobotern in der Architektur und die roboterbasierte Fertigung im Maßstab 1 : 1 sind Kernthemen dieser Arbeit. Mobile Robotersysteme müssen die gebaute Umgebung wahrnehmen und auf veränderte Bedingungen reaktiv eingehen können. Als Grundlage für die Dissertation dient die erforderliche Untersuchung des neuartigen Zusammenschlusses der roboterbasierten digitalen Fabrikation mit kognitiven Fähigkeiten. Der experimentelle Schwerpunkt dieser Forschungsarbeit liegt daher ebenso auf der digitalen Ansteuerung und Durchführung maschineller Bauprozesse wie auf der Entwicklung einer mobilen Robotereinheit und von erweiterten Rückkopplungs- und Lokalisierungstechniken durch Sensorik. Der Synergieeffekt zwischen den Forschungsbereichen Architektur und Experimentelle Informatik ist angesichts dieser interdisziplinären Themenbereiche von zentraler Bedeutung.The technical demands of future construction processes are becoming increasingly complex and require customised solutions. Computercontrolled production methods allow for the manufacture of individually designed building components without increasing outlay in terms of costs or time. In contrast to stationary machines, mobile units can be deployed directly on an existing building site and thus combine the capabilities of digitally defined elements with an in-situ construction technique. The core themes of this dissertation are the direct use of industrial robots in architecture and robot- assisted in-situ fabrication on a 1 : 1 scale. Mobile robotic systems must be able to perceive the constructed environment and respond to changing conditions. The necessary investigation of the innovative fusion of robot-based digital fabrication and cognitive abilities forms the basis of this research. Thus, the experimental focus of this research is on the development of a mobile robotic unit and advanced feedback and localisation techniques, as well as the digital management and implementation of mechanical construction processes. Due to the interdisciplinary nature of this subject area, the synergetic effect between the research areas of architecture and experimental computer science is of central importance
