Abstract: A verification method of multi-agent interaction policy is proposed based on model checking. The model of system is specified with obligation policy language and it is converted to the input model of model checker NuSMV based on its operational semantics, the properties of system depending on different types of policy conflicts are represented with temporal logic, and the violations of properties are detected by using NuSMV model checker, which can provide the counterexample and trace it back to the errors in interaction policy. The result shows that the method can improve the efficiency of verifying interaction policy, and it ensures the correctness of the design of Multi-Agent systems.
