Approaches founded on the use of modeling languages and frameworks are grouped under the banner of MBSE (Model Based Systems Engineering). The basic idea is that a model evolves over the system development life-cycle, until it becomes the built-to baseline. In this paper, we consider a modeling approach based on the use of a metamodeling architecture that focuses on the use of models as the primary artifacts of system development. We specifically address the use of MDA (Model Driven Architecture), which allows to increase the level of automation when evolving models from the very abstract representation of a system down to the system implementation, thus making easier (i.e., at reduced cost and effort) the analysis, development and testing activities. By applying MDA concepts and standards to MBSE approaches we obtain what we refer to as MDSE (Model Driven Systems Engineering). The paper illustrates a methodological template for MDSE and shows its application to the development of a software-intensive system.

However, BOM specifications suffer from interoperability issues as they cannot be automatically imported into model-driven simulation engineering environments based on UML and related standards. In this paper, we overcome this limitation by introducing BOM2UML, a model transformation to derive standard UML models from a BOM specification. We provide both a conceptual description of the transformation rules and the details of their implementation in ATL, the Atlas Transformation Language. We also show a preliminary output of the proposed transformation, applied to a set of BOM specifications of a simplified military application.}, keywords = {BOM, Computer simulation, HLA, Mathematical models, Model driven development, Model transformation, Specifications, Standards, UML, Unified Modeling Language}, isbn = {9781618397867}, issn = {07359276}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84876472367\&partnerID=40\&md5=60c7fa8c563ba58f48e298b7cc8fb1a1}, author = {Gianni, D. and Andrea D{\textquoteright}Ambrogio and Grasso, M.} } @conference {D{\textquoteright}Ambrogio2008460, title = {Distributed simulation of complex systems by use of an HLA-transparent simulation language}, booktitle = {2008 Asia Simulation Conference - 7th International Conference on System Simulation and Scientific Computing, ICSC 2008}, year = {2008}, note = {cited By 5}, pages = {460-467}, abstract = {The continuously decreasing cost of distributed systems gives academics and industry the advantage of using larger execution platforms and of reusing locally implemented software components. This is particularly true for the simulation of complex systems where the computational resources needed considerably increase with the model resolution and with the number of simulated entities. The development of such simulation systems, however, requires extra efforts compared to the conventional local ones. Example extra efforts are learning how to use the Distributed Simulation (DS) Standard (such as HLA) and the development of extra software for the synchronization and communication between the local and distributed environment. In this paper, we address the problem of defining a simulation language that can transparently support the development distributed simulation systems, by making the use of the DS standard transparent and also reducing the amount of extra software. The HLA transparent language we introduce is named jEQN, being Java-based and dealing with Extended Queueing Networks domains. The language approach, however, can be easily extended to any other DS Standard and modelling domain. {\textcopyright} 2008 IEEE.}, keywords = {Complex systems, Computational resources, Computer simulation languages, Computer software, Dielectric relaxation, Distributed environments, Distributed simulation systems, Distributed simulations, Distributed systems, Do-mains, Java programming language, Large scale systems, Linguistics, Model resolutions, Queueing networks, Simulation languages, Simulation systems, Software components, Standardization, Standards}, isbn = {9781424417872}, doi = {10.1109/ASC-ICSC.2008.4675405}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-58049176462\&partnerID=40\&md5=9610842bfbbce4f9f21f913927ec00c1}, author = {Andrea D{\textquoteright}Ambrogio and Gianni, D. and Iazeolla, G. and Pieroni, A.} } @conference {Angelaccio200695, title = {A model-driven framework for managing the QoS of collaborative P2P service-based applications}, booktitle = {Proceedings of the Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises, WETICE}, year = {2006}, note = {cited By 6}, pages = {95-100}, abstract = {Distributed and collaborative applications are rapidly converging towards the adoption of a computing paradigm based on service-oriented architectures, according to which an application results from the composition of a set of services in execution on networked server hosts.

In order to enable better QoS, service providers may employ overlay networks to bring applications closer to their consumers, overcoming slow backbone paths, network congestions and physical latencies.

A MDBS (Multi Data Base System) is a system that provides access to data from a collection of DBSs (Data Base Systems), called component DBSs, that are heterogeneous and distributed. The integration of the component DBSs into the MDBS is performed by a complex of functions termed gateway. This paper describes the design of a gateway based on the distributed object computing (DOC) approach, and compliant to the CORBA (Common Object Request Broker Architecture) standard. The approach is shown to introduce savings in design complexity and cost. The details of the approach are described in a gateway case study for the integration of a relational DBS into a MDBS.
