Dynamic composition and adaptation in adapt-medium

International audienceIn the presence of operational context changes, many applications must use dynamic adaptations in order to meet requirements. When an application has a set of distributed objects that collaborates to offer a particular function, adaptations involving simultaneous distributed processes may affect such collaborations, planning distributed adaptations is thus a complex task for developers. This paper presents Adapt-Medium, an architecture of adaptive distributed components. In the architecture, adaptations are realized by performing dynamic compositions of distributed components. We introduce a model-based process for 1) specifying architecture variants of such distributed components and 2) automatically generating adaptation plans that are performed at runtime to switch between architecture variants

Modelling information flow for organisations delivering microsystems technology

Motivated by recent growth and applications of microsystems technology (MST), companies within the MST domain are beginning to explore avenues for understanding, maintaining and improving information flow, within their organisations and to/from customers, with a view to enhancing delivery performance. Delivery for organisations is the flow of goods from sellers to buyers and a classic approach to understanding information flow is via the use of modelling techniques. Cont/d

Safety-Critical Systems and Agile Development: A Mapping Study

In the last decades, agile methods had a huge impact on how software is developed. In many cases, this has led to significant benefits, such as quality and speed of software deliveries to customers. However, safety-critical systems have widely been dismissed from benefiting from agile methods. Products that include safety critical aspects are therefore faced with a situation in which the development of safety-critical parts can significantly limit the potential speed-up through agile methods, for the full product, but also in the non-safety critical parts. For such products, the ability to develop safety-critical software in an agile way will generate a competitive advantage. In order to enable future research in this important area, we present in this paper a mapping of the current state of practice based on {a mixed method approach}. Starting from a workshop with experts from six large Swedish product development companies we develop a lens for our analysis. We then present a systematic mapping study on safety-critical systems and agile development through this lens in order to map potential benefits, challenges, and solution candidates for guiding future research.Comment: Accepted at Euromicro Conf. on Software Engineering and Advanced Applications 2018, Prague, Czech Republi

RECONCILING KNOWLEGDE MANAGEMENT AND E-COLLABORATION SYSTEMS: THE INFORMATION-DRIVEN KNOWLEDGE MANAGEMENT FRAMEWORK

In recent years, e-collaboration systems have emerged as an essential enabler of communication and collaboration between enterprises. Current trends in the area of e-collaboration emphasize the importance of effective collaborative knowledge management support in e-collaboration systems. Our research aims at proposing an intelligent infrastructure for the reconciliation of knowledge management and e-collaboration systems. The objective of the paper is to introduce a conceptual framework for designing and building the new infrastructure that supports specific characteristics of collaborative knowledge management in e-collaboration systems. The paper articulates how this framework enables efficient knowledge exploration and exploitation, before concluding with implications and recommendations for future developments in this area

On the Development and Management of Adaptive Business Collaborations.

Today’s business climate demands a high rate of change with which Information Technology (IT)-minded organizations are required to cope. Organizations face rapidly changing market conditions, new competitive pressures, new regulatory fiats that demand compliance, and new competitive threats. All of these situations and more drive the need for the IT infrastructure of an organization to respond quickly in support of new business models and requirements. This dissertation studies the adaptive development and management of such dynamic business models and requirements. A rule based environment is developed in which the people who develop and manage business collaborations in organizations can do so in a way that is as independent of specific implementation technologies as possible; and where they can take business requirements into consideration, and in which they can respond to changes as effectively as possible.
