MODULAR MODELLING AND ANALYSIS OF TIME-DEPENDENT SYSTEMS

This paper describes an approach to the analysis of time-dependent systems which combines discrete-event simulation and model-checking techniques. The approach rests on Merlin and Farber’s Time Petri Nets (TimePNs) and is supported by a Java toolbox TPN Designer which enables graphical modelling, simulation and translation into UPPAAL/Timed Automata, for exhaustive state space verification, of modular TimePN models. The paper discusses the potential of the proposed approach through its application to a real-time system model.
