Modelling multi-aspect negotiations in multiagent systems using petri nets

Abstract

Agent-based technologies are used to develop concurrent systems running in open environment. Research in multiagent systems is concerned with modelling and designing of communication between autonomous agents to make it successful. This work applies to negotiation as a form of communication between agents and concurrency of this process. We propose multi-aspect negotiation, which may be run concurrently between agents in autonomous bilateral negotiation threads using different negotiation strategies. High level Petri nets are known model to design concurrent and distributed systems working in the open environment such as the Internet. We have presented how to use the Petri nets formalism to design negotiating system. On the basis of implemented real-world application we have carried out an experiment, which shows the relationship between chosen strategies and negotiation effectiveness and verbosity.
