Applications of agent architectures to decision support in distributed simulation and training systems

This work develops the approach and presents the results of a new model for applying intelligent agents to complex distributed interactive simulation for command and control. In the framework of tactical command, control communications, computers and intelligence (C4I), software agents provide a novel approach for efficient decision support and distributed interactive mission training. An agent-based architecture for decision support is designed, implemented and is applied in a distributed interactive simulation to significantly enhance the command and control training during simulated exercises. The architecture is based on monitoring, evaluation, and advice agents, which cooperate to provide alternatives to the dec ision-maker in a time and resource constrained environment. The architecture is implemented and tested within the context of an AWACS Weapons Director trainer tool. The foundation of the work required a wide range of preliminary research topics to be covered, including real-time systems, resource allocation, agent-based computing, decision support systems, and distributed interactive simulations. The major contribution of our work is the construction of a multi-agent architecture and its application to an operational decision support system for command and control interactive simulation. The architectural design for the multi-agent system was drafted in the first stage of the work. In the next stage rules of engagement, objective and cost functions were determined in the AWACS (Airforce command and control) decision support domain. Finally, the multi-agent architecture was implemented and evaluated inside a distributed interactive simulation test-bed for AWACS Vv\u27Ds. The evaluation process combined individual and team use of the decision support system to improve the performance results of WD trainees. The decision support system is designed and implemented a distributed architecture for performance-oriented management of software agents. The approach provides new agent interaction protocols and utilizes agent performance monitoring and remote synchronization mechanisms. This multi-agent architecture enables direct and indirect agent communication as well as dynamic hierarchical agent coordination. Inter-agent communications use predefined interfaces, protocols, and open channels with specified ontology and semantics. Services can be requested and responses with results received over such communication modes. Both traditional (functional) parameters and nonfunctional (e.g. QoS, deadline, etc.) requirements and captured in service requests

Arguement in the humanities: A knowledge based approach

In this thesis I have a threefold purpose. I will attempt: (a) to present a generic design for a tool - the Argument Support Program - which can be of use in supporting the reasoning of archaeologists (and others especially, but not exclusively, in the humanities); (b) I will present a model of argumentation and debate as the theoretical orientation within which the model is developed; and, (c) I will suggest that this approach is a natural development of several strands of research within the artificial intelligence community. A tripartite model of argument is presented in terms of arguers, the argument structure produced and the argument domain or field. This model subsumes reasoning, interpretation and argument exchange or debate. It is maintained, further, that while this model is generally applicable, specific domains have particular styles of argument. The notion of argument style is discussed in terms of the types of reasoning used. The related concept of relevance in argument is discussed in terms of the specific tokens of these types which may be used in a particular argument. It is argued that archaeology is characterized, at least in part, by the use of argument by analogy and argument from theoretical principles or models. A design for a generic program - the Argument Support Program (ASP) - based on the theoretical principles is delineated. Details of the partial implementation of the model as a constrained debater in the domain of archaeology (ASP for archaeology or ASParch) are presented. Example runs which illustrate how the characterizing features of archaeology are dealt with are also presented as are examples of the various domain and system knowledge bases needed. The application of ASPs to other domains and areas such as literary criticism, legal reasoning and Darwinian theory is discussed. In the final chapter, the achievements and inadequacies of this research are summarized, possible reasons are presented for the inadequacies in the resulting system and future directions discussed

Negotiation capability : a conceptual model and reference practices

This research studies the topic of negotiation in the business field at a national and international level, and in particular the concept of negotiation capability, understanding that the negotiation processes generally depend on how skillful the negotiators are, not only in one-time negotiation but mainly in the maintenance of long term business relationships. As a theoretical framework, this thesis adopts a holistic view of the dynamic phenomenon of negotiation by studying the interconnectedness of the concepts emerged from the study: ethics, decision-making, leadership and emotional intelligence. Methodologically, this study employs a mixed method research approach, through a longitudinal perspective, based on a interpretive paradigm and constructivist approach and on the selection of qualitative analysis as well as qualitative data derived from the research method of grounded theory, techniques of observation, interviews, and complemented by the integration of Bibliometrics, as a quantitative method, for increased validity of the research findings. The results of this work offer a model of negotiation capability, which is the main objective of this research. The components of the model are a set of personal values, dimensions and reference practices that support the complex process of building and developing negotiation capability.Esta investigación estudia el tópico de la negociación en el ámbito empresarial a nivel nacional e internacional y en particular el concepto de capacidad de negociación, entendiendo que los procesos de negociación generalmente dependerán de la habilidad de los directivos. No sólo en negociaciones individuales, sino sobre todo en el mantenimiento de relaciones de negocio a largo plazo. Como marco teórico, esta tesis adopta una visión integral del dinámico fenómeno de la negociación mediante el estudio de la interrelación de los conceptos surgidos durante la investigación: la ética, la toma de decisiones, el liderazgo y la inteligencia emocional. Metodológicamente, este estudio emplea un enfoque de investigación de método mixto, a través de una perspectiva longitudinal, basado en un paradigma interpretativo y en un enfoque constructivista, así como en la selección de análisis y datos cualitativos, obtenidos a partir del método de investigación de la teoría fundamentada, técnicas de observación y entrevistas, complementado por la integración de la Bibliometría, como método cuantitativo, para incrementar la validez de los resultados de la investigación. Los resultados de este trabajo muestran el principal objetivo de esta investigación, que es la construcción de un modelo sobre la capacidad de negociación. Los componentes del modelo, son un conjunto de valores personales, dimensiones y prácticas de referencia, que soportan el complejo proceso de construcción y desarrollo de la capacidad de negociación.Postprint (published version

Processes of International Negotiations

Negotiations are essential mechanisms for the peaceful resolution of disputes and for maintaining stability in international relations. Negotiations can and should contribute to predictability, equity, and security among states. In achieving these goals, negotiations become important confidence-building measures. The increasing role of negotiations and of international organizations for managing the system of international order and for pursuing/achieving states' interests/policies through peaceful means has produced a fundamental evolution in the agenda, functions, and intensity of international negotiations. In the view of both researchers and negotiators over the recent past, the negotiations process that is organized along traditional lines is becoming more complex, difficult, and less effective. The processes of negotiations are in general taking more and more time and lagging behind the evolution of the international environment. Not only are the issues themselves more complex, but also, in the implementation of any agreements reached, the resolution of the issues involved will need to take place over a longer time and therefore to be managed jointly or multilaterally. Because of the increasing complexity of issues and the fast pace of changes affecting both national and international interests, it has become essential for international agreements to contain sufficient flexibility in certain of their provisions to permit dealing with uncertainty and the needs of the parties to adapt to new and changing circumstances. In this sense, international negotiations and agreements must be not only reactive but also anticipatory. These considerations indicate that a much-needed approach is one which is concerned specifically with bringing about a multinational, multicultural, and multidisciplinary understanding of and perspective on international negotiations and which also bridges the gap between practitioners and researchers. A specific objective and unique aspect of the IIASA Project on the Processes of International Negotiations (PIN Project), which started in April 1986 and was funded by the Carnegie Corporation, is the international, multidisciplinary approach brought to bear on all of the Project's activities. This was especially evident at the IIASA Conference on the Processes of International Negotiations, held in May 1987. The PIN networks in IIASA's member countries played an essential role in this Conference. To keep the focus of the work on substantive issues and on relevant applications-oriented results, while taking into account the importance and impact of different cultural and political systems in the various national approaches to negotiations, both practitioners and researchers involved in the processes of negotiations made presentations at the PIN Conference and took part in the panel discussions. These presentations form the basis for the chapters of this book. The goals of the Conference were to foster increased communication and understanding between practitioners and researchers and among various research disciplines, to present and discuss research results, and to identify possible future research activities. The participation and interaction of both high-level negotiations practitioners and researchers were considered especially valuable and unique aspects of the Conference. All of the subjects dealt with at the Conference have direct and obvious relevance to improving negotiations outcomes on, and the ability to deal effectively with, such issues as the transboundary effects (environmental, economic, etc.) of technological risk, security and confidence-building measures, and international economic cooperation -- all of which are high on the negotiations agenda of many countries
