In this paper, we introduce a methodology to predict the execution time of a DS system during its design phase. The methodology is based on a model-building approach that, basing on the design documents of the DS system, first produces its performance model and then evaluates it. The model includes components such as middleware to use (e.g., the HLA RTI), the set of DS execution hosts and the set of host interconnection networks. The methodology is applied to determine whether or not producing the distributed simulator of a given system may be advantageous in terms of execution time with respect to a conventional local simulator. An example use of the methodology is presented and validated by a comparison of the time-prediction with the actual execution time of the implemented DS system. {\textcopyright} 2010 IEEE.}, keywords = {Building performance, Computer simulation, Design documents, Design phase, Development cycle, Distributed simulations, Execution time, Forecasting, Middleware, Model buildings, Performance Model, Simulation model}, isbn = {9781424472918}, doi = {10.1109/PADS.2010.5471669}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-77954092922\&partnerID=40\&md5=2d68a6f0b45ad790df832f3da1a2ad43}, author = {Gianni, D. and Iazeolla, G. and Andrea D{\textquoteright}Ambrogio} } @article {D{\textquoteright}Ambrogio2009625, title = {Simulation model building of traffic intersections}, journal = {Simulation Modelling Practice and Theory}, volume = {17}, number = {4}, year = {2009}, note = {cited By 9}, pages = {625-640}, abstract = {Designers of traffic systems might take advantage of the simulation-before-construction approach that allows them to study the behavior of a new or existing system by use of simulation models. Nevertheless, the use of simulation models is often hindered by the fact that the model building activity is a critical, time consuming and error prone activity if performed by use of experience and intuition only. Moreover, traffic designers do not usually have the necessary skills to effectively carry out system simulation. This paper overcomes such problems by introducing a model building method, thus enabling traffic designers to seamlessly introduce simulation-before-construction into their best practices. The method is applied to the building of simulation models of traffic intersections, with an example application to a real-world intersection. {\textcopyright} 2008 Elsevier B.V.

Indeed the model can be used in the early stages of the product lifecycle to predict the product compliance with the user performance requirements. This paper deals with software performance model building. Only a few methods and tools have been introduced for performance model automatic building, which would be of great interest to software developers, since existing performance methods and tools require a deep knowledge of performance theory. This paper illustrates the design of a tool for automatically building software performance models. The produced model is a queueing network. The design is based on recently published standards like MOF and XMI, that facilitate the easy interchange of models between different tools (e.g., software development tools, evaluation tools, etc.).}, keywords = {Automatic buildings, Design, Information science, Java programming language, Model buildings, MOF, Product compliance, Product development, Queueing networks, Software development tools, Software engineering, Software performance, Software performance modeling, Tools, UML, XMI}, isbn = {0889864640; 9780889864641}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84882959712\&partnerID=40\&md5=5efce578e953ca65d5eff685949b9a32}, author = {Andrea D{\textquoteright}Ambrogio and Iazeolla, G.} }
