An increasing number of computer systems are being viewed in terms of autonomous agents. There are two main drivers to this trend. Firstly, agents are being advocated as a next generation model for engineering complex, distributed systems (Jennings 2000; Wooldridge 1997). Secondly, agents are being used as an overarching framework for bringing together the(More)
While temporal logic in its various forms has proven essential to reason about reactive systems, agent-based scenarios are typically specified by considering high-level agents attitudes. In particular, specification languages based on epistemic logic [7], or logics for knowledge, have proven useful in a variety of areas including robotics, security(More)
In the last few yearswe havewitnessed a surge of business-to-consumer and business-to-business commerce operated on the Internet. However, most current electronic commerce systems are little more than electronic catalogues that allow a user to purchase a product under predetermined and inflexible terms and conditions. We believe that in the next few years(More)
We present a framework for verifying temporal and epistemic properties of multi-agent systems by means of bounded model checking. We use interpreted systems as underlying semantics. We give details of the proposed technique, and show how it can be applied to the "attacking generals problem", a typical example of oordination in multi-agent systems.
We investigate an extension of the formalism of interpreted systems by Halpern and colleagues to model the correct behaviour of agents. The semantical model allows for the representation and reasoning about states of correct and incorrect functioning behaviour of the agents, and of the system as a whole. We axiomatise this semantic class by mapping it into(More)
We explore the paradigm of artifact-centric systems from a knowledge-based perspective. We provide a semantics based on interpreted-systems to interpret a first-order temporalepistemic language with identity in a multi-agent setting. We consider the model checking problem for this language and provide abstraction results. We isolate a natural subclass of(More)
We show that the problem of model checking multidimensional modal logics can be reduced to the problem of model checking ARCTL, an extension of the temporal logic CTL with action labels and operators to reason about actions. In particular, we introduce a methodology for model checking a temporal-epistemic logic by building upon an extension of the model(More)
We present a methodology for the verification of multi-agent systems, whose properties are specified by means of a modal logic that includes a temporal, an epistemic, and a modal operator to reason about correct behaviour of agents. The verification technique relies on model checking via ordered binary decision diagrams. We present an implementation and(More)
Artifact systems are a novel paradigm for specifying and implementing business processes described in terms of interacting modules called artifacts. Artifacts consist of data and lifecycle models, accounting for the relational structure of the artifact state and its possible evolutions over time. We consider the problem of verifying artifact systems against(More)
