This document is the final report of a project supported by the European Community via an individual fellowship through the Human Capital and Mobility Programme. Title of this project is "A Methodology and Computational Support Environment for Cooperative Design of Knowledge Systems". This report is essentially a collection of papers published by the author in the context of this research project. A brief summary of the research problem and final results introduces this work. This report (i) discusses a method to concurrent design in which multi-functional groups actively participate; (ii) proposes a multi-agent distributed software architecture for the development of computer-based tools to support our design method; and (iii) illustrates the development of a design environment on the World Wide Web, implementing aspects of the conceptual software architecture
