However, existing EA frameworks lack modeling approaches to represent the increasing complexity and coupling of modern enterprises, as these frameworks do not distinguish architectural blocks supporting the different enterprise lifecycle processes, such as operation, maintenance and governance. In this paper, we propose the Viewband concept, which can be used to explicitly introduce lifecycle modeling, thus overcoming the limitations of existing EA frameworks. We also present an overlay methodology to implement the Viewband concept by use of standard modeling structures in existing EA frameworks, thus gaining compliance with currently available technologies and documentation standards. We show the application of the Viewband concept, and the related implementation methodology, through a simplified example enterprise model in UPDM (Unified Profile for DoDAF and MODAF). {\textcopyright} 2012 IEEE.}, keywords = {Architectural frameworks, Documentation standards, Enterprise Architecture, Enterprise engineering, Framework, Implementation methodology, Industry, Life cycle, Models, Regulatory compliance, Systems engineering, UML, UPDM}, isbn = {9781467329750}, doi = {10.1109/SYSoSE.2012.6384147}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84879760525\&partnerID=40\&md5=460d2bf88dfbefdc28866d34620db577}, author = {Gianni, D. and Andrea D{\textquoteright}Ambrogio} } @conference {Gianni2009, title = {Dissimjade: A framework for the development of agent-based distributed simulation systems}, booktitle = {SIMUTools 2009 - 2nd International ICST Conference on Simulation Tools and Techniques}, year = {2009}, note = {cited By 6}, publisher = {ICST}, organization = {ICST}, abstract = {The adoption of an agent-based approach that incorporates intelligence, adaptation and learning abilities has proved to significantly increase the realism and the accuracy of the simulation. Simulation systems of such a kind, however, require computational resources that might be considerable for a single agent, so to become unfeasible when the number of simulated agents scales up. A distributed environment is thus needed to allow the execution of such simulation systems, particularly in the case of scenarios populated by a large number of agents. Building an agent-based distributed simulation system, however, requires both specific expertise and knowledge of distributed simulation standards and a non-negligible amount of effort to develop ad-hoc components. This paper introduces a simulation framework named DisSimJADE, which enables the incorporation of distributed simulation facilities into existing agent-based systems. DisSimJADE is built on top of the popular agent-based framework JADE and allows to define agent-based simulation systems that can be transparently executed either in a local or distributed, therefore bringing significant savings in terms of effort and development time. In addition, DisSimJADE provides a uniform interface to the JADE framework, which further facilitates the production of distributed simulation systems to developers of JADE-based multi-agent systems.}, keywords = {Agent based simulation, Discrete event simulation, Distributed computer systems, Distributed simulations, Framework, HLA, Intelligent agents, JADE, Multi agent systems, Silicate minerals}, isbn = {9789639799455}, doi = {10.4108/ICST.SIMUTOOLS2009.5725}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84922896723\&partnerID=40\&md5=2916ed218703e0d34cb973b665080ff4}, author = {Gianni, D. and Andrea D{\textquoteright}Ambrogio and Iazeolla, G.}, editor = {Stea G., Dalle O., Perrone L.F., Wainer G.} } @conference {D{\textquoteright}Ambrogio2007210, title = {Software technologies for the interoperability and reusability of distributed simulators}, booktitle = {SISO European Simulation Interoperability Workshop 2007, EURO SIW 2007}, year = {2007}, note = {cited By 2}, pages = {210-219}, abstract = {Giving interoperability and reusability capabilities to distributed simulators is fundamental to the widespread use of distributed simulation. The HLA standard has introduced considerable improvements with respect to previous standards, though it suffers from shortcomings such as (1) lack of interoperability among different IEEE-compliant implementations, (2) no support to the adaptation and integration of individual federates and (3) poor reusability, which is limited to entire federates only. In this paper, we present two independent technologies that overcome such shortcomings. The first technology consists of a CORBA-HLA architecture that overcomes limitation (1), the second technology is a new development framework called SimJ that overcomes limitations (2) and (3). The CORBA-HLA architecture decouples federates from the specific HLA implementation so that federates can be effortlessly run on top of any HLA implementation that exposes services through an IEEE-complaint IDL interface. The SimJ framework eases the development of individual federates by providing a uniform and standard interface for local and distributed simulators, and makes it possible the reuse of components smaller than entire federates in both local and distributed simulators.}, keywords = {Adaptability, Common object request broker architecture (CORBA), Computer architecture, Computer software reusability, Distributed simulations, Framework, HLA, Interoperability, Middleware, Reusability, Simulators, Software technology, Standard interface, Technology}, isbn = {9781615671700}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84865354509\&partnerID=40\&md5=3cad39842c91176c439ae7bf7e6b17a1}, author = {Andrea D{\textquoteright}Ambrogio and Gianni, D. and Iazeolla, G.} }
