Verification criteria for a compositional model for reactive systems

Abstract

System compositioddecomposition has to be analyzed in terms of temporal constraints associated with the components' external interjiace. In this paper the analysis is focused on the propagation of temporal constraints along the structural hierarchy, thus showing that in many cases missing temporal constraints can be evaluated on the basis of the temporal constraints known. A set of criteria for the veriBcation of the temporal constraints in a compositional model is presented. A specific graphical notation is proposed. The application of the criteria to a real problem is illustrated by using TROL, an object-oriented real time language.

Data Sources and Models for Integrated Mobility and Transport Solutions

“…Such data results are at the basis of the what-if analysis approaches (orange blocks) to assess and set up different strategies for sustainable mobility, which can solve specific critical or hypothetical conditions in order to improve mobility and transport scenarios. Finally, all the data, results and information are presented to operators (and maybe to final users) by means of operative dashboards [ 122 ] as well as aggregated and integrated into smart city Digital Twins representations [ 123 , 124 ] exploiting client-side business logic [ 125 ] to guarantee seamless interactivity.…”
