  • 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 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. ...
  • An architecture for self-organising evolvable virtual machines 

    Nowostawski, Mariusz; Purvis, Martin; Cranefield, Stephen
    Contemporary software systems are exposed to demanding, dynamic, and unpredictable environments where the traditional adaptability mechanisms may not be sufficient. To imitate and fully benefit from life-like adaptability ...
  • 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. ...
  • 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 connectionist computational architecture based on an optical thin-film model 

    Purvis, Martin; Li, Xiaodong
    A novel connectionist architecture that differs from conventional architectures based on the neuroanatomy of biological organisms is described. The proposed scheme is based on the model of multilayered optical thin-films, ...
  • Connectionist-based information systems: a proposed research theme 

    Kasabov, Nikola; Purvis, Martin; Sallis, Philip
    General Characteristics of the Theme • Emerging technology with rapidly growing practical applications • Nationally and internationally recognised leadership of the University of Otago • Already established organisation ...
  • 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 ...
  • Extending agent messaging to enable OO information exchange 

    Cranefield, Stephen; Purvis, Martin
    It is canonical practice in agent-based systems to use a declarative format for the exchange of information. The increasing usage and facility of object-oriented tools and techniques, however, suggests there may be benefits ...
  • Extracting data from Second Life 

    Ranathunga, Surangika; Cranefield, Stephen; Purvis, Martin
