Product development is one of the most important drivers of innovation. Methods, procedures and systems evoke, enable and support innovation. The papers presented in this book, show that answers can only be composed out of a variety of solutions where psychological, economical and technical research results are taken into account.

The proceedings represent trends in Product Development concerning industrial users and vendors as well as scientific research aspects.

The following topics are covered: Design Theory, Product Design, Requirements, Collaborative Engineering, Complex Design, Mechatronics, Reverse Engineering, Virtual Prototyping, CAE, KBE and PLM.

The globalisation of markets and the expansion of product responsibility into the entire product life cycle lead to an increasing competitive situation for nationally and internationally operating companies. Therefore, to win this competition the use of the most effective and efficient resources regarding the whole product life cycle is necessary. Since these resources are globally distributed the different tasks both within a phase of product life cycle and those spread over different phases are distributed as well. The global interference of these tasks requires a close multilateral co-operation of the companies concerned. Current information- and communication technologies and modern management concepts offer high potentials to meet these requirements. The international seminar of CIRP on Life Cycle Engineering titled "Life Cycle Networks" was a forum for the presentation and discussion of current research work and recent advancements on these strategic issues for current and future engineering. Complex requirements and innovative solutions to support and realise Life Cycle Networks has been revealed and summerised. The employment of information technology to support both specific phases of product life cycle and holistic approaches will be the main focus. This volume contains the papers presented at the seminar which provide opportunities to identify the state-of-the-art and address future needs. The parts in this volume correspond to the sessions of the seminar and are presented under the following headings: Life Cycle Management; Life Cycle Design; Design for Environment; Design for Recycling; Life Cycle Assessment; Disassembly; IT-Networks.

Die Tagung CAD '92 ist die erste Fachtagung der Gesellschaft f}r Informatik zum Thema "Rechnerunterst}tztes Entwerfen und Konstruieren". Schwerpunkte der Tagung sind neue Konzepte zur Realisierung anwendungsorientierter CAD-Systeme. Der Einsatz und die Entwicklung zuk}nftiger Generationen von CAD-Systemen werden von den folgenden Aspekten gepr{gt sein: - zunehmende Funktionalit{t - Erweiterung von Basis-Systemen um Anwendungsmodule - produktorientierte Konstruktions- und Arbeitsplanungslogiken - benutzergerechte und anwendungsbezogene Gestaltung der Mensch-Maschine-Kommunikation - anforderungsgerechte Informationsbereitstellung f}r die Produktionsvorbereitung - Anwendung von Methoden der Wissensverarbeitung - zunehmende internationale Standardisierung - Wirtschaftlichkeit und Produktivit{t Das Ziel der Tagung ist daher die Darstellung innovativer Technologien, Methodologien undKonzepte der Informatik f}r den integrativen und wirtschaftlichen Einsatz der Rechnerunterst}tzung in Entwicklung, Konstruktion und Arbeitsplanung.
