Abstract
This paper proposes a modular approach to verifying
whether a large discrete event system is nonconflicting.
The new approach avoids computing the synchronous
product of a large set of finite-state machines. Instead, the
synchronous product is computed gradually, and intermediate
results are simplified using conflict-preserving abstractions
based on process-algebraic results about fair testing. Heuristics
are used to choose between different possible abstractions.
Experimental results show that the method is applicable to
finite-state machine models of industrial scale and brings
considerable improvements in performance over other methods.
