A Model-Based Approach to Impact Analysis Using Model Differencing
Impact analysis is concerned with the identification of consequences of
changes and is therefore an important activity for software evolution. In
modelbased software development, models are core artifacts, which are often
used to generate essential parts of a software system. Changes to a model can
thus substantially affect different artifacts of a software system. In this
paper, we propose a modelbased approach to impact analysis, in which explicit
impact rules can be specified in a domain specific language (DSL). These impact
rules define consequences of designated UML class diagram changes on software
artifacts and the need of dependent activities such as data evolution. The UML
class diagram changes are identified automatically using model differencing.
The advantage of using explicit impact rules is that they enable the
formalization of knowledge about a product. By explicitly defining this
knowledge, it is possible to create a checklist with hints about development
steps that are (potentially) necessary to manage the evolution. To validate the
feasibility of our approach, we provide results of a case study.Comment: 16 pages, 5 figures, In: Proceedings of the 8th International

Discovering Knowledge through Highly Interactive Information Based Systems
[EN] The new Internet era has increased a production of digital data. The mankind had an easy way to the knowledge access never before, but at the same time the rapidly increasing rate of new data, the ease of duplication and transmission of these data across the Net, the new available channels for information dissemination, the large amounts of historical data, questionable
quality of the existing data and so on are issues for information overload that causes more difficult to make decision using the right data. Soft-computing techniques for decision support systems and business intelligent systems present pretty interesting and necessary solutions for data management and supporting decision-making processes, but the last step at the decision chain is usually supported by a human agent that has to process the system outcomes
in form of reports or visualizations. These kinds of information representations
are not enough to make decisions because of behind them could be hidden information patterns that are not obvious for automatic data processing and humans must interact with these data representation in order to
discover knowledge. According to this, the current special issue is devoted to
present nine experiences that combine visualization and visual analytics techniques, data mining methods, intelligent recommendation agents, user centered evaluation and usability patterns, etc. in interactive systems as a key issue for knowledge discovering in advanced and emerging information systems.[ES] La nueva era de Internet ha aumentado la producciĂłn de datos digitales. Nunca nates la humanidad ha tenido una manera más fácil el acceso a los conocimientos, pero al mismo tiempo el rápido aumento de la tasa de nuevos datos, la facilidad de duplicaciĂłn y transmisiĂłn de estos datos a travĂ©s de la red, los nuevos canales disponibles para la difusiĂłn de informaciĂłn, las grandes cantidades de los datos histĂłricos, cuestionable calidad de los datos existentes y asĂ sucesivamente, son temas de la sobrecarga de informaciĂłn que hace más difĂcil tomar decisiones con la informaciĂłn correcta. TĂ©cnicas de Soft-computing para los sistemas de apoyo a las decisiones y sistemas inteligentes de negocios presentan soluciones muy interesantes y necesarias para la gestiĂłn de datos y procesos de apoyo a la toma de decisiones, pero el Ăşltimo paso en la cadena de decisiones suele ser apoyados por un agente humano que tiene que procesar los resultados del sistema de en forma de informes o visualizaciones. Este tipo de representaciones de informaciĂłn no son suficientes para tomar decisiones debido detrás de ellos podrĂan ser patrones de informaciĂłn ocultos que no son obvios para el procesamiento automático de datos y los seres humanos deben interactuar con estos representaciĂłn de datos con el fin de descubrir el conocimiento. De acuerdo con esto, el presente nĂşmero especial está dedicado a nueve experiencias actuales que combinan tĂ©cnicas de visualizaciĂłn y de análisis visual, mĂ©todos de minerĂa de datos, agentes de recomendaciĂłn inteligentes y evaluaciĂłn centrada en el usuario y patrones de usabilidad, etc. En sistemas interactivos como un tema clave para el descubrimiento de conocimiento en los sistemas de informaciĂłn avanzados y emergentes
The Internet's Effects on Global Production Networks: Challenges and Opportunities for Managing in Developing Asia
Placing global production networks (GPN) on the Internet poses a fundamental challenge, but also creates new opportunities for managing in Developing Asia. Network flagships can now select best-performing suppliers on a global scale, increasing the pressure on Asian suppliers. But the transition form EDI to the Internet may also provide new opportunities for Asian suppliers, by reducing barriers to network entry, and by enhancing knowledge diffusion. A conceptual framework is introduced to assess how the Internet reshapes business organization and GPN. That framework is applied to one of the role models of managing in Asia, Taiwan's Acer Group. The paper highlights a vicious circle that must be broken to reap the benefits of the Internet: Asian firms must reduce a huge efficiency gap between manufacturing and the management of supporting digital information systems (DIS). The challenge is to embrace the Internet as flexible infrastructures that support not only information exchange, but also knowledge sharing, creation and utilization. The Internet facilities this task: it provides new opportunities for the outsourcing of mission-critical support services.

A Requirements-Based Taxonomy of Software Product Line Evolution
Software product lines are, by their very nature, complex software systems.
Due to the interconnectedness of the various products in the product line any form of evolution becomes significantly more complex than in a single system situation. So far most work on product line evolution has focused on specific approaches to supporting special cases of the evolution problem. In this paper, we take a different approach and provide a broad taxonomy of requirements-driven evolution in software product lines. This serves as a basis for the identification of requirements on evolution support
