Abstract
This paper deals with verification of timed and untimed linear properties of the Interval Timed Colored Petri Net model. This model can simulate other timed colored Petri nets and allows describing large and complex real–time systems. We propose here to contract its generally infinite state space into a graph that captures all linear properties of the model. The resulting graph is finite iff, the model is bounded (the set of its reachable markings is finite). In this case, linear properties of the model can be verified on the graph using, for example, the classical linear model checking techniques.
Keywords: Formal methods, model checking, timed models, timed colored Petri net, state space contraction, linear properties.
Resumen
Este artículo se ocupa de la verificación de las propiedades lineales temporizadas y no temporizadas del modelo de redes de Petri coloreadas con intervalos temporizados. Este modelo puede simular otras redes de Petri coloreadas temporizadas y permite describir grandes y complejos sistemas en tiempo real. Nosotros proponemos contraer el espacio generalmente infinito, en un grafo que capture todas las propiedades lineales del modelo. El grafo resultante es finito, si y solamenti si, el modelo tiene límites (el conjunto de sus marcas accesibles es finito). En este caso, las propiedades lineales del modelo se pueden verificar en el grafo resultante, utilizando, por ejemplo, técnicas de comprobación del modelo lineal clásico.
Palabras clave: Métodos formales, comprobación modelo, modelos temporizados, red de Petri coloreada con intervalos temporizados, contracción del espacio del estado, propiedades lineares.
