Summary
It cannot always be assumed that agents will behave as they are supposed to behave. Agents may fail to comply with system norms deliberately, in open agent systems or other competitive settings, or unintentionally, in unreliable environments because of factors beyond their control. In addition to analysing system properties that hold if specifications/norms are followed correctly, it is also necessary to predict, test, and verify the properties that hold if system norms are violated, and to test the effectiveness of introducing proposed control, enforcement, and recovery mechanisms. C+++ is an extended form of the action language C+ of Giunchiglia, Lee, Lifschitz, McCain, and Turner, designed for representing norms of behaviour and institutional aspects of (human or computer) societies. We present the permission component of C+++ and then illustrate on a simple example how it can be used in conjunction with standard model checkers for the temporal logic CTL to verify system properties in the case where agents may fail to comply with system norms.
