14:00 - 18:00 Tutorial:  Interaction Protocol Engineering for Multiagent Systems

Lecturers: Marc-Philippe Huget (Agent ART Group, University of Liverpool, UK) and Jean-Luc Koning (Leibniz-Esisar, France)

Interaction is one of the key components in multiagent systems that enables the agents to coordinate in order for them to fulfil their tasks. The aim of this tutorial is to give a complete view of design of interaction protocols from the specification of requirements to executable versions of protocols. This tutorial is a practical one and relies on well-known protocols stemming from the research domain of multiagent systems like Contract Net protocol or English Auction protocol.

After a general introduction on interaction and a detailed one interaction in multiagent systems, we present a complete interaction protocol engineering from the analysis stage to the protocol synthesis and the validation of this synthesis.  This engineering advocated for interaction protocols in multiagent systems has been derived from communication protocol engineering in distributed systems.  We motivate this engineering approach on interaction protocols and then describe the whole life-cycle.

First, the protocol analysis stage, explains how to describe protocols and how to build a full specification of requirements.  Second, we focus on the formal description stage.  Contrary to the first stage which provides a natural language representation of a protocol, we deal here with formal methods for describing protocols, either coming from distributed systems (automata, Petri nets, LOTOS) or coming from multiagent systems (Agent-UML, Temporal logic).  Third, we tackle the validation issue, i.e., how to check properties on the obtained protocol.  There are essentially two methods for this purpose: reachability analysis and model checking.  We explain how one can make use of them.  Fourth, highlight how to an actual program from the formal description and explain what pitfalls appear from this stage and how to fix them.  Finally, we touch on how to validate and actual implement the protocols.  This conformance testing stage checks for flaws in the obtained program.

Tutorial attendees do not need to have any special background.  Practitioners will easily follow the tutorial since the basics are explained at the beginning of the tutorial. Moreover, researchers and practitioners from user interfaces and expert systems among others will find in this tutorial a set of techniques that could be of help for their research or development. By the end of the tutorial, attendees will know how to formally describe protocols and how to design them given an actual specification of requirements.
