Abstract

Lossy VASS (vector addition systems with states) are defined as a subclass of VASS in analogy to lossy FIFO-channel systems. They can be used to model concurrent systems with unreliable communication. We analyze the decidability of model checking problems for lossy systems and several branching-time and linear-time temporal logics. We present an almost complete picture of the decidability of model checking for normal VASS, lossy VASS and lossy VASS with test for zero.
