Model Checking GSM-Based Multi-Agent Systems

Abstract: Artifact systems are a novel paradigm for implementing service oriented computing. Business artifacts include both data and process descriptions at interface level thereby providing more sophisticated and powerful service inter-operation capabilities. In this paper we put forward a technique for the practical verification of business artifacts in the context of multi-agent systems. We extend GSM, a modelling language for artifact systems, to multi-agent systems and map it into a variant of AC-MAS, a semantics for reasoning about artifact systems. We introduce a symbolic model checker for verifying GSM-based multi-agent systems. We evaluate the tool on a scenario from the service community.
