  • An adaptive distributed workflow system framework 

    Purvis, Martin; Lemalu, Selena; Purvis, Maryam A.
    Workflow management systems are increasingly used to assist the automation of business processes that involve the exchange of documents, information, or task execution results. Recent developments in distributed information ...
  • Agent based web service composition in the context of a supply-chain based workflow 

    Savarimuthu, Bastin Tony Roy; Purvis, Martin; Purvis, Maryam A.
    With the advent of Web Services, more and more business organizations make their services available on the Internet through Web Services and also use other services that are available on the corporate Intranet. From the ...
  • Agent modelling with Petri nets 

    Purvis, Martin; Cranefield, Stephen
    The use of intelligent software agents is a modelling paradigm that is gaining increasing attention in the applications of distributed systems. This paper identifies essential characteristics of agents and shows how they ...
  • An agent-based architecture for software tool coordination 

    Cranefield, Stephen; Purvis, Martin
    This paper presents a practical multi-agent architecture for assisting users to coordinate the use of both special and general purpose software tools for performing tasks in a given problem domain. The architecture is open ...
  • Agent-based container terminal optimisation 

    Winikoff, Michael; Wagner, Hanno-Felix; Young, Thomas; Cranefield, Stephen; Jarquin, Roger; Li, Guannan; Martin, Brent; Unland, Rainer
    Container terminals play a critical role in international shipping and are under pressure to cope with increasing container traffic. The problem of managing container terminals effectively has a number of characteristics ...
  • Agent-based integration of web services with workflow management systems 

    Savarimuthu, Bastin Tony Roy; Purvis, Martin; Cranefield, Stephen; Purvis, Maryam A.
    Rapid changes in the business environment call for more flexible and adaptive workflow systems. Researchers have proposed that Workflow Management Systems (WfMSs) comprising multiple agents can provide these capabilities. ...
  • Assurance of agent systems: What role should formal verification play? 

    Winikoff, Michael
    In this paper we consider the broader issue of gaining assurance that an agent system will behave appropriately when it is deployed. We ask to what extent this problem is addressed by existing research into formal verification. ...
  • Automating information processing tasks: an agent-based architecture 

    Cranefield, Stephen; McKinlay, Bryce; Moreale, Emanuela; Purvis, Martin
    This paper describes an agent-based architecture designed to provide automation support for users who perform information processing tasks using a collection of distributed and disparate software tools and on-line resources. ...
  • Bridging the gap between the Model-Driven Architecture and ontology engineering 

    Cranefield, Stephen; Pan, Jin
    This paper discusses the potential benefits to ontology engineering in making the toolset of the Object Management Group’s model-driven architecture (MDA) applicable to ontology modelling, and describes the design of an ...
  • Building privacy infrastructure for culturally sensitive information of New Zealand Maori 

    Deng, Xianglin; Foukia, Noria; Savarimuthu, Bastin Tony Roy
    This paper proposes to design a mechanism that will allow Maori users to specify their privacy preferences related to their culture when a software system asks for culturally sensitive information. We first identify various ...
  • Causal agent modelling: a unifying paradigm for systems and organisations 

    Purvis, Martin; Cranefield, Stephen
    With the increasing size, complexity and interconnectedness of systems and organisations, there is a growing need for high level modelling approaches that span the range of application domains. Causal agent modelling offers ...
  • A collaborative Web-based issue based information system (IBIS) framework 

    Ebadi, Toktam; Purvis, Martin; Purvis, Maryam A.
    This research focuses on the design and development of an IBIS-based tool called IBISMod, which facilitates a distributed and collaborative decision-making process. IBIS-based systems help analysts and designers in the ...
  • Communicating agents: an emerging approach for distributed heterogeneous systems 

    Cranefield, Stephen; Gorman, Paul; Purvis, Martin
    The concept of an intelligent software agent has emerged from its origins in artificial intelligence laboratories to become an important basis for the development of distributed systems in the mainstream computer science ...
  • Communicative acts and interaction protocols in a distributed information system 

    Nowostawski, Mariusz; Carter, Dan; Cranefield, Stephen; Purvis, Martin
    In FIPA-style multi-agent systems, agents coordinate their activities by sending messages representing particular communicative acts (or performatives). Agent communication languages must strike a balance between simplicity ...
  • The concept of autonomy in distributed computation and multi-agent systems 

    Nowostawski, Mariusz; Purvis, Martin
    The concept of autonomy is a central concept in distributed computational systems and in multi-agent systems in particular. With diverse implications in philosophy and despite frequent use in social sciences and the theory ...
  • A distributed architecture for environmental information systems 

    Purvis, Martin; Cranefield, Stephen; Nowostawski, Mariusz
    The increasing availability and variety of large environmental data sets is opening new opportunities for data mining and useful cross-referencing of disparate environmental data sets distributed over a network. In order ...
  • Distributed information access in New Zealand
