Abstract. In order to design and analyse complex systems, modelers need formal models with two contradictory requirements: a high expressivity and the decidability of behavioural p...
Discrete event dynamic systems may have extremely large state spaces. For their analysis, it is usual to relax the description by removing the integrality constraints. Applying thi...
Abstract. In many cases, complex system behaviors are naturally modeled as nonlinear differential equations. However, these equations are often hard to analyze because of "sti...
We introduce discrete pushdown timed automata that are timed automata with integer-valued clocks augmented with a pushdown stack. A con guration of a discrete pushdown timed automa...
