The proposed approach transforms a specification written in a semi-formal language into a stochastic model to be used for reliability evaluation. The paper assumes an UML-based system specification and introduces a method to map the specification onto a failure model. The method enables software designers with no specific knowledge of reliability theory to predict at design time the reliability of the final product, thus introducing lifecycle reliability prediction into their development best practices. The method is illustrated by use of an application case study that deals with the development of distributed software. A software architecture that allows the method to be easily integrated into UML-based software development environments is also introduced. The architecture is based on the use of XML (eXtensible Markup Language) to represent both the UML system specification and the failure model.}, keywords = {Application programs, Automatic modeling, Component based software, Forecasting, Formal languages, Reliability assessments, Reliability Evaluation, Reliability prediction, Reliability theory, Semi-formal languages, Software development environment, Software engineering, Software reliability, Specifications, XML, XML (extensible markup language)}, isbn = {0889863237; 9780889863231}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84904159409\&partnerID=40\&md5=e3371411e5b757b27cda93c405253da1}, author = {Andrea D{\textquoteright}Ambrogio and Iazeolla, G. and Mirandola, R.} } @conference {Gianni201031, title = {A methodology to predict the performance of distributed simulations}, booktitle = {Proceedings - Workshop on Principles of Advanced and Distributed Simulation, PADS}, year = {2010}, note = {cited By 5}, pages = {31-39}, abstract = {Predicting the time-performance of a Distributed Simulation (DS) system may be of interest to evaluate system alternatives during the development cycle, before the system is implemented. 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} }
