Abstract (en)

[origin: WO2005109196A1] Disclosed is a method for determining deadlocks in secondary processes for a system model that is described in an object-oriented manner. Said method comprises the following steps: a) all active objects of the object-oriented system model are extracted; b) the transitions between the objects are identified; c) the state-waiting relations between the objects are established; d) potential deadlocks are determined as cycles of entities of two or more different objects, which wait for each other, and for each deadlock; e) all potential paths resulting in a determined deadlock are verified by means of a simulated execution of the system model.
