Abstract
The purpose of this paper is to present a concept for configuring dynamic and ready-to-implement supply network structures. This concept is based on a (real) business case from the fashion industry where order, logistics and production management processes are entirely consumer-driven. Only after the consumer has configured and customised his made-to-measure fashion product and placed his order, the actual constellation of partners in the supply network is determined and business processes initiated. The focus of the paper is on the methodological approach of defining and modelling the underlying business model. © 2004 by Springer Science+Business Media New York.

Abstract
This paper proposes a social networking perspective on the e-manufacturing area. A short justification of the social network-perspective as applied to manufacturing organizations is made, focusing on methods and theoretical approaches. Then, it is speculated how social networking can be a paradigm for the management of networks of manufacturing enterprises. The management relationship (fostering collaboration and cooperation) and their support through new information systems architectures are the key issues. Finally, some research directions are discussed, focussing on new engineering paradigms.

Abstract
This paper reviews relevant aspects of the formation and dissolution of interorganizational networks (ION) aiming at define requirements for systems managing knowledge networks in such environments. Firstly, the concept of networking and virtual organizing is reviewed. Then a major work on formation of ION is analysed and some conclusions are drawn regarding the design of ION. Finally, the requirements for knowledge management systems in the formation and dissolution of ION are discussed.

Abstract
This paper presents an approach to the identification of requirements for the implementation of e-business solutions in small and medium sized enterprises (SME). The approach is based oil the so-called reference models whose main purpose is to guide the process of deriving the detailed requirements for business processes and information systems support, regarding e-business activities. Firstly, an overview of the particular aspects and main difficulties of the adoption of e-business by SME is presented. This overview justifies the methodology for the implementation of e-business in SME, developed within the EC funded project MEDIAT-SME, shortly described here. Next, it is focused a particular aspect of this methodology, the reference models approach, followed by an example of its application on a real SME. Finally, the advantages and difficulties of the approach are discussed.

Abstract
The main purpose of this paper is to present a preliminary study on the impact of stratospheric ozone on tropospheric ozone levels under specific atmospheric dynamical conditions. It is well accepted that stratospheric ozone can be the source of part of the tropospheric ozone. Previous studies indicate that the mechanism responsible for this ozone intrusion occurs generally in several steps or just in a single step, usually associated with strong upward motion. In the first part of this paper, the methodology used in order to identify particular short-term episodes, potentially associated to the abovementioned phenomenon, is presented. Several episodes have been studied occurring during 14 years of ozone data collection, recorded by the Portuguese ozone network. Then, an analysis of the dynamical atmospheric conditions associated to previously identified episodes have been developed in order to verify the possibility of stratospheric contribution for the observed ozone level in each episode. Two of these episodes show a relatively good relationship between synoptical patterns related to stratospheric intrusions and backward trajectories. For these cases, the possibility of stratospheric origin should not be discarded before further study is developed.
