The aim of the conference PROLAMA T'95 on "Life Cycle Modelling for Innovative Products and Processes" was to present, discuss and summarize requirements and solutions for sustainable product development and manufacturing processes. The employment of information technology to support the development of new strategies will be the main focus. This volume contains the papers presented at the conference which provide opportunities to identify the state-of-the-art and address future requirements. A variety of branches with their specific products and manufacturing processes were the basis for intensive discussions. The relationships between aims for sustainability, costs, quality, and performance are of significant interest. Changes in organizational structures, outsourcing and globalization are important parameters for novel product development and manufacturing strategies. The link to standardization will be emphasised. The papers in this volume are presented under the following headings: Advanced Strategies; Life Cycle Modelling; Decision Support; Assembly and Disassembly; Rapid and Virtual Prototyping; Sustainable Manufacturing; Design for Environment; Specific Methods; Recycling; Feature Technology; Distributed Product Development and Manufacturing. A large number of papers was submitted for consideration. Members of the International Program Committee worked assiduously to select appropriate papers. Thanks are due to them. Furthermore, we express our thanks to the local organization committee as well as to the officials of the "International Federation for Information Processing" (IFIP) for their efforts, which helped to make this conference possible.
