Agents and Roles: Refinement in Alternating-Time Temporal Logic

摘要

We present a notion of refinement between agent-oriented systems defined using alternating-time temporal logic (ATL). The refinement relation provides a framework for defining roles in a society of interacting agents, and formalising a relation of conformance between agents and roles. The refinement relation also allows us to construct abstractions in order to make verification more tractable.
