Model Checking of Time Petri Nets Using the State Class Timed Automaton
In this paper, we propose a method for building the state class graph of a bounded time Petri net (TPN) as a timed automaton (TA), which we call the state class timed automaton. We...

Planning Time-Minimal Safe Paths Amidst Unpredictably Moving Obstacles
In this paper we discuss the problem of planning safe paths amidst unpredictably moving obstacles in the plane. Given the initial positions and the maximum speeds of the moving ob...
