Model-Based Systems Engineering Tools Devoloping the GUILTE System

The GUILTE (Guiding Urban InteLligent Traffic & Environment) system is part of a large, complex, interdisciplinary, socio-technical domain at the agenda of world leaders, local authorities, academia, and society-at-large. The main purposes of the system are to provide an integrated development framework for the municipalities, and to support the operations of the urban traffic through Intelligent Transportation Systems, highlighting two fundamental aspects: the evaluation of the related environmental impacts, and the dissemination of information to the citizens, endorsing their involvement and participation. The development process of the GUILTE system was supported by a novel Model-Based Systems Engineering methodology, the LITHE (Agile Systems Modelling Engineering), which aims to lightening the complexity and burdensome of the existing methodologies by emphasizing agile principles such as continuous communication, feedback, stakeholders involvement, short iterations and rapid response, and also by a graphical tool, the GRAPHITE matrices, developed to support model-based cooperative development environments.
