Management Structure Based Government Enterprise Architecture Framework Adaption in Situ
2017
Part 1: Regular Papers; International audience; The fragmentation of the public sector makes it difficult to manage strategically and architecturally as a whole. Enterprise Architecture (EA) is considered as an improvement to that. Architectural modeling and visualization of the general management strategy plans along with parallel database development in a local government forms the primary data in the longitudinal case study using Action Design Research Method. To find a proper organizational fit for the EA framework in public sector, we reflect on how the current state architectural descriptions got organized in situ in a deep corporate hierarchy, and what were the emerging management ne…
Specification of modelling languages in a flexible meta-model architecture
2010
Originally, meta-models were used to specify the structure (abstract syntax) of modelling languages. This is reflected both in meta-languages like MOF and Ecore, and the four-layer meta-model architecture. Presently, meta-modelling is used for specification of complete languages. In this situation, it turns out that the traditional meta-languages are not always expressive enough to capture all language aspects. This usually implies the use of more than one metalanguage in the meta-model architecture to cover the different language aspects. There are many approaches to address this challenge. In this paper, we analyze these approaches, and based on this analysis, we re-think the meta-model a…
A CAN Fieldbus Based Architecture for Distributed Control Systems Implementation
2003
Abstract The application of distributed systems theory to the implementation of industrial control systems is one of the best options to develop simple, scalable and physically distributed control systems. Following this line, our group has proposed a new architecture based on Rule Nets (RN) as an HLP over CAN fieldbus for the implementation of Distributed Systems. This architecture has been applied to several control applications, obtaining excellent results. The most outstanding feature of the architecture was its simplicity in the control systems design, without any efficiency loss. New capabilities have been added to improve its features and develop new analysis tools, in order to incre…
An expert system hybrid architecture to support experiment management
2014
Specific expert systems are used for supporting, speeding-up and adding precision to in silico experimentation in many domains. In particular, many experimentalists exhibit a growing interest in workflow management systems for making a pipeline of experiments. Unfortunately, these type of systems does not integrate a systematic approach or a support component for the workflow composition/reuse. For this reason, in this paper we propose a knowledge-based hybrid architecture for designing expert systems that are able to support experiment management. This architecture defines a reference cognitive space and a proper ontology that describe the state of a problem by means of three different per…
Fifth Generation Networking Principles for a Service Driven Future Internet Architecture
2010
Published version of an article published in Wireless Personal Communications, vol. 57:393-411. Also available from the publisher at: http://dx.doi.org/10.1007/s11277-010-0076-7 The vision of all-IP networks where IP forms the simple common layer understandable across the whole network has undeniable advantages. However, such simplicity comes as a major hurdle to flexibility and functionality to the architecture. This is evident from the increasingly numerous and complex engineering solutions and optimizations required to accommodate essential qualities like mobility, security, realtime communication support etc or to mitigate the shortcomings inherent in the 'traditional Internet' architec…
Government Enterprise Architecture Grid Adaptation in Finland
2009
In government, support for strategic political steering, administrative and cross-sectoral development, and integration of processes and systems can be sought out of enterprise architecture (EA) planning. To facilitate this, a proper EA method covering essential government levels is needed. A constructive case study has been carried out to create an adaptation model of Finnish government EA (GEA) grid. The study builds on general principles of method adaptation and observations about GEA method engineering and its pilot adaptations in Finnish State Administration. The model presents systematic guidelines for situational GEA grid adaptation and reuse in Finnish State administration. The mode…
Business architecture development at public administration - Insights from government EA method engineering project in Finland
2008
Governments worldwide are concerned for efficient production of services to customers. To improve quality of services and to make service production more efficient, information and communication technology (ICT) is largely exploited in public administration (PA). Succeeding in this exploitation calls for large-scale planning which embraces issues from strategic to technological level. In this planning the notion of enterprise architecture (EA) is commonly applied. One of the sub-architectures of EA is business architecture (BA). BA planning is challenging in PA due to a large number of stakeholders, a wide set of customers, and solid and hierarchical structures of organizations. To support …
A unified radio control architecture for prototyping adaptive wireless protocols
2016
Experimental optimization of wireless protocols and validation of novel solutions is often problematic, due to limited configuration space present in commercial wireless interfaces as well as complexity of monolithic driver implementation on SDR-based experimentation platforms. To overcome these limitations a novel software architecture is proposed, called WiSHFUL, devised to allow: i) maximal exploitation of radio functionalities available in current radio chips, and ii) clean separation between the logic for optimizing the radio protocols (i.e. radio control) and the definition of these protocols.
Toward a Reference Architecture for Archival Systems
2013
Long-term preservation of product data is imperative for many organizations. A product data archive should be designed to ensure information accessibility and understanding over time. Approaches such as the Open Archival Information System (OAIS) Reference Model and the Audit and Certification of Trustworthy Digital Repositories (ACTDR) provide a framework for conceptually describing and evaluating archives. These approaches are generic and do not focus on particular contexts or content types. Enterprise architecture provides a way to describe systems in their potentially complex environments.
A New HLA-Based Distributed Control Architecture for Agricultural Teams of Robots in Hybrid Applications with Real and Simulated Devices or Environme…
2011
The control architecture is one of the most important part of agricultural robotics and other robotic systems. Furthermore its importance increases when the system involves a group of heterogeneous robots that should cooperate to achieve a global goal. A new control architecture is introduced in this paper for groups of robots in charge of doing maintenance tasks in agricultural environments. Some important features such as scalability, code reuse, hardware abstraction and data distribution have been considered in the design of the new architecture. Furthermore, coordination and cooperation among the different elements in the system is allowed in the proposed control system. By integrating …
