Abstract

The notion of I/O compatibility of reactive systems is defined. It models the fact that two systems can be connected and establish a correct dialogue through their input and output events. I/O compatibility covers safeness and liveness properties that can be checked with a polynomial-time decision procedure. The relationship between observational equivalence, I/O compatibility and input properness is also studied with the aim at supporting the proposal of transformations for the synthesis of reactive systems. Finally, a set of Petri net transformations that preserve I/O compatibility are shown as an example of application of the theory presented in this paper.
