A case for an international consortium on system-of-systems engineering
A system-of-systems (SoS) conceptualization is essential in resolving issues involving heterogeneous independently operable systems to achieve a unique purpose. Successful operation as an SoS requires communication among appropriate individuals and groups across enterprises through an effective protocol. This paper presents a position on the creation of a consortium of concerned system engineers and scientists worldwide to examine the problems and solutions strategies associated with SoS. The consortium could lead efforts in clarifying ambiguities and in seeking remedies to numerous open questions with respect to SoS analysis, SoS engineering (SoSE), as well as differences between systems engineering (SE) and SoSE. The mission of this consortium is envisioned to: 1) act as a neutral party; 2) provide a forum to put forth Calls to Action; and 3) establish a community of interest to recommend a set of solutions. <br /
ASSERT: a step towards reliable and scientific system and software engineering.
International audienceThe ASSERT (www.assert-project.org) project (Automated proof-based System and Software Engineering for Real-Time systems) is an integrated project partially funded by the European Commission within the Information Society Technologies priority of the 6th Framework Program in the area of embedded systems. The project is coordinated by the European Space Agency (ESA) in the TEC directorate (Technical and Quality management), Software Systems division. The assert consortium is made of 28 partners (see the full list in section 7) representing the space industry, research laboratories, software houses and tool developers. The project started in September 2004 and has ended in December 2007. The main objective of ASSERT is to change the way system and software engineering is performed today to adopt a more reliable and scientific approach based on modelling, preservation of system properties and model transformation down to the final code.The current results include a process, a set of tool prototypes and case studies demonstrating the validity of the overall approach. The project results will now be disseminated in operational projects through the support of ESA, the tool and technologies providers and the industrialists from the space sector

EU-China collaboration in design: research in Web-enabled collaborative design supported by the Asia-Link and Asia IT&C projects
The research of Web-enabled collaboration in total design supported by the European Union's Asia Link project [1] and Asia IT&C project is reported in this paper. The two projects both aim at enhancing research collaboration between the EU and China. The Virtual Research Institute (VRI) is described first, which is the platform for the collaboration for the Asia Link project and is established by utilizing the advanced Web techniques; and then, the framework for the collaboration and the Web techniques involved in the research are presented which represent the major research of the Asia IT&C project. The effective collaboration between the project partners and the impacts of the project outcome on the partnership are also discussed
Value-based Design of Collaboration Processes for e-Commerce
Designing cross-organizational e-business applications faces the problem that the collaborating businesses must align their commercial interests without any central decision making authority. The design process must therefore yield a clear view of the commercial value of the collaboration for each economic actor, as well as a clear specification of the activities to be performed by each actor and a specification of information systems to be used by each actor. We present guidelines for designing the value network of the collaboration, which shows the commercial value of the collaboration for each participating actor. We then present guidelines for transforming the value network into process models, which show the feasibility of implementing the value network in the business processes of the actors. Our approach has been developed in different consultancy projects. We illustrate our approach with a consultancy project performed at a company that we will call the Amsterdam Times
SimCADO - an instrument data simulator package for MICADO at the E-ELT
MICADO will be the first-light wide-field imager for the European Extremely
Large Telescope (E-ELT) and will provide difiraction limited imaging (7mas at
1.2mm) over a ~53 arcsecond field of view. In order to support various
consortium activities we have developed a first version of SimCADO: an
instrument simulator for MICADO. SimCADO uses the results of the detailed
simulation efforts conducted for each of the separate consortium-internal work
packages in order to generate a model of the optical path from source to
detector readout. SimCADO is thus a tool to provide scientific context to both
the science and instrument development teams who are ultimately responsible for
the final design and future capabilities of the MICADO instrument. Here we
present an overview of the inner workings of SimCADO and outline our plan for
its further development.Comment: to appear in Ground-based and Airborne Instrumentation for Astronomy

An open source collaboration infrastructure for Calibre
The study of Free and Open Source (Libre) software and the benefits provided by its processes and products to collaborative software development has been somewhat ad hoc. Each project wishing to use tools and techniques drawn from Libre software conducts its own research, thus duplicating effort, consequently there is a lack of established community practice on which new projects can draw. Long-standing intuitive theories of Libre development lack empirical validation. The long-term goal is to provide a resource to guide the evolution of Libre-software projects, from inception to maturity. The CALIBRE project is a co-ordination action aiming to address these issues through its research, its wider educational goals, and with an open invitation to the community to contribute. To succeed, the CALIBRE project needs an effective technological infrastructure which must support internal and external collaboration, communication and contribution to the project.
The requirements of CALIBRE are similar to those of a Libre software project; this suggests that adopting a SourceForge-style environment which will be incrementally enhanced with further specialised tools as the requirements become better understood will be a sensible strategy
