Agent-based technology can provide increased flexibility for automated manufacturing systems if agents are designed to modify their problem-solving interaction styles to best fit their situations. These interaction styles are described by agent autonomy levels, which are assigned to goals an agent intends to achieve. This paper explores the implications of(More)
Multi-agent systems require adaptability to perform effectively in complex and dynamic environments. This article shows that agents should be able to benefit from dynamically adapting their decision-making frameworks. A decision-making framework describes the set of multi-agent decision-making interactions exercised by members of an agent group in the(More)
— One way to handle data mining problems where class prior probabilities and/or misclassification costs between classes are highly unequal is to resample the data until a new, desired class distribution in the training data is achieved. Many resampling techniques have been proposed in the past, and the relationship between resampling and cost-sensitive(More)
Autonomy is an often cited but rarely agreed upon agent characteristic. As the demand for agents capable of adjustable autonomy increases, a formal definition of agent autonomy becomes necessary to provide a foundation for work in the area as well as to support operational deployment of the concept. This paper presents such a definition. Based on this(More)
F uture manned space operations will include a greater use of automation than we currently see. 1 For example, semiautonomous robots and software agents will perform difficult tasks while operating unattended most of the time. As these automated agents become more prevalent, human contact with them will occur more often and become more routine, so designing(More)
Current manned space operations employ policies and protocols to specify an etiquette for human-human interaction. This space operations etiquette presumes that operations are conducted synchronously from a few centralized locations-a control center or space vehicle. The availability of automated control software, portable computing platforms, and wireless(More)
The introduction and operation of heart, lung and liver transplantation services in Australia have been assisted by a Nationally Funded Centres policy adopted by health ministers. Assessment for eligibility for support under the program has been undertaken by the Australian Health Technology Advisory Committee. Outcomes/survival rates at transplantation(More)
This paper explores the nature of conflict in agent-based systems. A conflict classification scheme based on a differentiation between goal, plan, and belief conflicts is presented. A formal definition of these three conflict classes is provided. A three layered representation of conflict is employed. Each layer is assigned to its respective conflict type(More)
The practical deployment of distributed agent-based systems mandates that each agent behave sensibly. This paper focuses on the development of flexible, responsive, adaptive systems based on Sensible Agents. Sensible Agents perceive, process, and respond based on an understanding of both local and system goals. Each agent is capable of (1) deliberative or(More)
