Model checking of message flow diagrams

摘要

Model checking for message sequence charts (MSCs), message sequence chart graphs and hierarchical message sequence chart graphs (HMSCs) is provided. To verify the behavior of a given MSC, MSC graph and HMSC, a specification automaton is constructed. This specification automaton specifies the undesirable executions of the model under analysis. From the model under analysis, linearizations are defined from the model and a finite test automaton is constructed from the linearizations. The test automaton and the specification automaton are combined and it is determined whether there is an execution in the intersection. Where no state in the specification automaton is reachable from the test automaton, the model is verified.
