  • 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-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. ...
  • 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 ...
  • Facilitating collaboration in a distributed software development environment using P2P architecture 

    Purvis, Martin; Savarimuthu, Bastin Tony Roy; Purvis, Maryam A.
    This paper describes efforts to facilitate collaborative work in a distributed environment by providing infrastructure that facilitates the understanding of inter-connected processes involved and how they interact. In this ...
  • A framework for distributed workflow systems 

    Purvis, Martin; Lemalu, Selena; Purvis, Maryam A.
    Workflow management systems (WFMS) are being adopted to assist the automation of business processes that involve the exchange of information. As a result of developments in distributed information system technology, it is ...
  • How do norms emerge in multi-agent societies? Mechanisms design 

    Savarimuthu, Bastin Tony Roy; Cranefield, Stephen; Purvis, Martin; Purvis, Maryam A.
    Norms are shared expectations of behaviours that exist in human societies. Norms help societies by increasing the predictability of individual behaviours and by improving co-operation and collaboration among members. Norms ...
  • Interaction protocols for a network of environmental problem solvers 

    Purvis, Martin; Hwang, Peter; Cranefield, Stephen; Schievink, Martin; Purvis, Maryam A.
    Environmental management and emergency response often involves the joint cooperation of a network of distributed problem solvers, each of which may be specialised for a specific task or problem domain. Some of these problem ...
  • Multi-agent system interaction protocols in a dynamically changing environment 

    Purvis, Martin; Cranefield, Stephen; Nowostawski, Mariusz; Purvis, Maryam A.
    An area where multi-agent systems can be put to effective use is for the case of an open collection of autonomous problem solvers in a dynamically changing environment. One example of such a situation is that of environmental ...
  • Norm identification in multi-agent societies 

    Savarimuthu, Bastin Tony Roy; Cranefield, Stephen; Purvis, Maryam A.; Purvis, Martin K.
    In normative multi-agent systems, the question of “how an agent identifies a norm in an agent society” has not received much attention. This paper aims at addressing this question. To this end, this paper proposes an ...
  • Partner selection mechanisms for agent cooperation 

    Ebadi, Toktam; Purvis, Martin; Purvis, Maryam A.
    In a multi-agent system, a single agent may not be capable of completing complex tasks. Therefore agents are required to form a team to fulfill the task requirements. In this paper an agent model is introduced that ...
  • Role model based mechanism for norm emergence in artificial agent societies 

    Savarimuthu, Bastin Tony Roy; Cranefield, Stephen; Purvis, Martin; Purvis, Maryam A.
    In this paper we propose a mechanism for norm emergence based on role models. The mechanism uses the concept of normative advice whereby the role models provide advice to the follower agents. Our mechanism is built using ...
  • Software effort estimation: Harmonizing algorithms and domain knowledge in an integrated data mining approach 

    Purvis, Martin; Deng, Jeremiah D.; Purvis, Maryam A.
    Software development effort estimation is important for quality management in the software development industry, yet its automation still remains a challenging issue. Applying machine learning algorithms alone often can ...
  • A software framework for application development using ZigBee protocol 

    Savarimuthu, Bastin Tony Roy; Bruce, Morgan; Purvis, Maryam A.
    The problem with the uptake of new technologies such as ZigBee is the lack of development environments that help in faster application software development. This paper describes a software framework for application development ...
  • Tag based model for knowledge sharing in agent society 

    Savarimuthu, Sharmila; Purvis, Martin; Purvis, Maryam A.
    In this paper we discuss a tag-based model that facilitates knowledge sharing in the context of agents playing the knowledge sharing game. Sharing the knowledge incurs a cost for the sharing agent, and thus non-sharing is ...
  • Vector opinion dynamics: An extended model for consensus in social networks 

    Alaali, Alya; Savarimuthu, Bastin Tony Roy; Purvis, Maryam A.
    Most people hold a variety of opinions on different topics ranging from sports, entertainment, spiritual beliefs to moral principles. These can be based on a personal reflection and evaluation or on their interactions with ...
