This paper presents a design method for re-using existing interaction protocols in agent-based control applications. In particular, this paper presents a general set of criteria for classifying interaction situations and matching them with existing interaction protocols that are able to resolve the interaction situations. This classification scheme is based solely on criteria derived from the specification of an interaction situation and thus enables a designer to select a suitable interaction protocol for these interaction problems without going through all the interaction protocols available. This design method completes the DACS methodology for agent-oriented analysis and design of control systems.
