Lomuscio A, Ezekiel J, 2009, Combining fault injection and model checking to verify fault tolerance in multi-agent systems, Proceedings of the International Joint Conference on Autonomous Agents and Multiagent Systems, AAMAS, Vol: 1, Pages: 86-93, ISSN: 1548-8403

The ability to guarantee that a system will continue to operate correctly under degraded conditions is key to the success of adopting multi-agent systems (MAS) as a paradigm for designing complex agent based fault tolerant systems. In order to provide such a guarantee, practically usable tools and techniques for verifying fault tolerant MAS architectures are urgently required. In this paper we address this requirement by combining automatic fault injection with model check-ing to verify fault tolerance in MAS. We present a generic method to mutate a model of a correctly behaving system into a faulty one, and show how the mutated model can be used to reason about fault tolerance, which includes recovery from faults. The usefulness of the proposed method is demonstrated by injecting automatically a fault into a sender-receiver protocol, and verifying temporal and epis- Temic specifications of the protocol's fault tolerance using the MCMAS model checker.

Cohen M, Dam M, Russo F, Lomuscio Aet al., 2009, Abstraction in model checking multi-agent systems, Proceedings of the International Joint Conference on Autonomous Agents and Multiagent Systems, AAMAS, Vol: 1, Pages: 710-717, ISSN: 1548-8403

We present an abstraction technique for multi-agent, systems preserving temporal-epistcrnic specifications. We abstract a multi-agent system, defined in the interpreted systems framework, by collapsing the local states and actions of each agent in the system. We show that the resulting abstract system simulates the concrete system, from which we obtain a preservation theorem: If a temporal-epistemic specification holds on the abstract system, the specification also holds on the concrete one. In principle this permits us to model check the abstract system rather than the concrete one, thereby saving time and space in the verification step. We illustrate the abstraction technique with two examples. The first example, a card game, illustrates the potential savings in the cost of model checking a typical MAS scenario. In the second example, the abstraction technique is used to verify a communication protocol with an arbitrarily large data domain.

Lomuscio A, Qu H, Solanki M, 2008, Towards verifying contract regulated service composition, Pages: 254-261

We report on a novel approach to (semi-)automatically compile and verify contract-regulated service compositions. We specify web services and the contracts governing them as WSBPEL behaviours. We compile WSBPEL behaviours into the specialised system description language ISPL, to be used with the model checker MCMAS to verify behaviours automatically. We use the formalism of temporal-epistemic logic suitably extended to deal with compliance/violations of contracts. We illustrate these concepts using a motivating example whose state space is approximately 106 and discuss experimental results. © 2008 IEEE.

Belardinelli F, Lomuscio A, 2008, A complete first-order logic of knowledge and time, Pages: 705-714

We introduce and investigate quantified interpreted systems, a semantics to reason about knowledge and time in a firstorder setting. We provide an axiomatisation, which we show to be sound and complete. We utilise the formalism to study message passing systems (Lamport 1978; Fagin et al 1995) in a first-order setting, and compare the results obtained to those available for the propositional case.

Lomuscio A, Qu H, Solanki M, 2008, Towards verifying compliance in agent-based Web service compositions, Proceedings of the International Joint Conference on Autonomous Agents and Multiagent Systems, AAMAS, Vol: 1, Pages: 262-269, ISSN: 1548-8403

We explore the problem of specification and verification of compliance in agent based Web service compositions. We use the formalism of temporal-epistemic logic suitably extended to deal with compliance/violations of contracts. We illustrate these concepts using a motivating example where the behaviours of participating agents are governed by contracts. The composition is specified in OWL-S and mapped to our chosen formalism. Finally we use an existing symbolic model checker to verify the example specification whose state space is approximately 221 and discuss experimental results.

We investigate quantified interpreted systems, a semantics for multiagent systems in which agents can reason about individuals, their properties, and the relationships among them. We analyse a first-order epistemic language interpreted on this semantics and show soundness and completeness of Q.S5n, an axiomatisation for these structures. © 2007 IFAAMAS.

We present an axiomatisation for an extension of a temporal epistemic logic with an epistemic "reset" operator defined on the intersection between epistemic and temporal relations. Additionally we show the logic has the finite model property, hence it is decidable. © 2007 IFAAMAS.
