During the development of context aware applications a context management component must traditionally be created. This task requires specialist context lifecycle management expertise and hence can be a significant deterrent to application development. It also removes the developers focus from differentiation of their application to an oft repeated development task. This issue can be addressed ...

Web services are playing a pivotal role in e-business, service intelligence, service science and information systems. This article will examine how the main players make decisions for activities in web service lifecycle (WSLC) and propose a holistic model for decision making in web services. More specifically, this article first examines main players in web services. It also reviews the existin...

Many technologies have lifecycles that are shorter than the lifecycle of the product they are in. Lifecycle mismatches caused by the obsolescence of technology (and particularly the obsolescence of electronic parts) results in high sustainment costs for long field life systems, e.g., avionics and military systems. This paper presents a methodology for performing optimum design refresh planning ...

Thinking in terms of SoS brings a 180 change in viewpoint. In traditional embedded systems design (being a subsystem in itself) we focus on how to effectively design those embedded subsystems to implement the functions of a device.This device plays a role in the physical world. With the introduction of embedded networking we move to cyber-physical systems in which these embedded subsystems now ...

This paper introduces an integrated modeling approach that has been used to design and implement the ColNet platform. ColNet is the result of creating an integrated system, supporting distributed business processes design and execution in a Collaborative Network (CN) belonging to an Open Ecosystem (VBE). The work has been carried out as a part of the FP7 REMPLANET European Project, which aims a...

Manufacturing companies are facing the challenge to cope with individualized process chains in spite of high market dynamics. In order to achieve high process efficiency by realizing logistic targets, two main leverages can be identified: adjustment of production structure and configuration of production control. The production structure represents the layout and arrangement of machines, the or...

Electric’s and electronics’ content in the high performance luxury segment’s vehicles is continuously increasing. Dynamically controlled safety features, passenger comfort, information and entertainment and operational convenience are the field of permanent innovation. To guarantee an appropriate level of quality for this permanently innovated features requires robust design techniques (analysi...

Systems required to exhibit high operational reliability often rely on some form of fault protection to recognize and respond to faults, preventing faults’ escalation to catastrophic failures. Integrated System Health Management (ISHM) extends the functionality of fault protection to both scale to more complex systems (and systems of systems), and to maintain capability rather than just avert c...

Introducing an SOA in a company brings new challenges for the existing management. Small loosely coupled services allow the Enterprise Architecture to flexibly adapt to existing business processes that themselves depend on changing market environments. SOA, however, introduces a new implicit system complexity. Service Governance approaches address this issue by introducing management processes ...

Tree disease epidemics are a global problem, impacting food security, biodiversity and national economies. The potential for conservation and breeding in trees is hampered by complex genomes and long lifecycles, with most species lacking genomic resources. The European Ash tree Fraxinus excelsior is being devastated by the fungal pathogen Hymenoscyphus fraxineus, which causes ash dieback diseas...
