    Interest-based negotiation in multi-agent systems
    rahwan, iyad ( 2004)
    Software systems involving autonomous interacting software entities (or agents) present new challenges in computer science and software engineering. A particularly challenging problem is the engineering of various forms of interaction among agents. Interaction may be aimed at enabling agents to coordinate their activities, cooperate to reach common objectives, or exchange resources to better achieve their individual objectives. This thesis is concerned with negotiation: a process through which multiple self-interested agents can reach agreement over the exchange of scarce resources. In particular, I focus on settings where agents have limited or uncertain information, precluding them from making optimal individual decisions. I demonstrate that this form of bounded-rationality may lead agents to sub-optimal negotiation agreements. I argue that rational dialogue based on the exchange of arguments can enable agents to overcome this problem. Since agents make decisions based on particular underlying reasons, namely their interests, beliefs and planning knowledge, then rational dialogue over these reasons can enable agents to refine their individual decisions and consequently reach better agreements. I refer to this form of interaction as “interested-based negotiation.” (For complete abstract open document)

    Agents for logistics: a provisional agreement approach
    Perugini, Don ( 2006-02)
    The thesis solves a challenging problem in military logistics for tasks such as transportation scheduling and combinatorial auctions. A conceptual model has been developed that captures the organisational business processes involved and an effective implementation suitable for computer software agents. The protocol facilitates planning and task allocation among organisations in decentralised, dynamic and open environments.
