    Postdiction is the task of finding the possible pasts of a physical system, given its model and current state. We present an appropriately modified version of Kuipers' QSIM algorithm to perform postdiction by reverse qualitative simulation. The necessary changes to the algorithm are explained and the closed world assumption is discussed in this new light. The new algorithm can be used for diagnost... View full abstract»

  • Choice-free Petri nets: a model for deterministic concurrent systems with bulk services and arrivals

    Among discrete event systems, those exhibiting concurrency are especially challenging, requiring the use of formal methods to deal with them. Petri nets are a well-established such formalism. The structure theory aims at overcoming the state space explosion problem, inherent to the analysis of concurrent systems, by bridging structural and behavioral properties. To date, this has been successfully... View full abstract»

    In this paper, we address a critical issue of cooperative problem solving: the existence of conflict among distributed agents. In particular, we focus our study on cooperative knowledge-based systems. To obtain a better understanding and more balanced judgement of multiagent conflict, we provide a general scheme to study the logical structure of multiagent conflict and rational strategies of copin...

  • Information-efficient control of discrete event stochastic systems

    Publication Year: 1997, Page(s):23 - 33

    A state of a discrete event stochastic system (DESS) can be represented by a tuple of time-varying discrete parameters. The authors have extended the theory of controlled discrete event systems developed by Ramadge, Wonham and other researchers to stochastic modeling and performance measurement. This work presents some important characteristics of the DESS model. The problem of making the most eff... View full abstract»

  • Discrimination gain to optimize detection and classification

    Publication Year: 1997, Page(s):112 - 116

    A method for managing agile sensors to optimize detection and classification based on discrimination gain is presented. Expected discrimination gain is used to determine threshold settings and search order for a collection of discrete detection cells. This is applied in a low signal-to-noise environment where target-containing cells must be sampled many times before a target can be detected or cla... View full abstract»

    To successfully interact with and learn from humans in cooperative modes, robots need a mechanism for recognizing, characterizing, and emulating human skills. In particular, it is our interest to develop the mechanism for recognizing and emulating simple human actions, i.e., a simple activity in a manual operation where no sensory feedback is available. To this end, we have developed a method to m... View full abstract»

  • The modified Dempster-Shafer approach to classification

    This paper describes “modified Dempster-Shafer” (MDS), an approach to object identification which incorporates Bayesian prior distributions into an altered Dempster-Shafer rule of combination. The MDS combination rule reduces, under strong independence assumptions, to a special case of Bayes' rule. We show that MDS has rigorous probabilistic foundations in the theory of random sets. We...

  • A discrete event system model of business system-a systems theoretic foundation for information systems analysis. I

    Publication Year: 1997, Page(s):1 - 10

    A variety of information systems methodologies for information systems analysis have been proposed. Though each methodology has its own effective concepts and tools, there still does not seem to exist a rigorous model of a business system. In this paper a general model of business systems is proposed. The model describes the whole mechanism of typical routine processing of business tasks with slip... View full abstract»

  • High speed flexible fuzzy hardware for fuzzy information processing

    In this paper, we present a system called KAFA (Kaist Fuzzy Accelerator) which provides various fuzzy inference methods and fuzzy set operations. The basic idea of this study is to develop a more general purpose hardware system. The architecture has SIMD structure, which consists of two parts; a system control unit (main controller), and an arithmetic unit (fuzzy processing element (FPE)). Microin... View full abstract»

    We present an approach to embedding expert systems within an object-oriented simulation environment that facilitates the creation of classes of expert system model elements that can be interfaced with other model components. Previous work has shown how distributed expert systems can be defined as modular components of simulations models. This article illustrates their usefulness in fractal archite... View full abstract»

  • Dynamic scheduling of design activities with resource constraints

    A design process can be represented as a network of design activities. A number of design projects may be undertaken simultaneously. This paper deals with the problem of scheduling design activities of multiple design projects competing for the limited available resources. The problem of determining a schedule subject to precedence and resource constraints is difficult to solve. It becomes even mo... View full abstract»

  • Meaning of dataflow diagram and entity life history-a systems theoretic foundation for information systems analysis. II

    For part I see ibid., p.1-10. Dataflow diagrams and entity life histories are widely-used tools in information systems methodologies. The tools are far more effective than natural language, though their meanings have not yet been clarified. This paper shows how the model developed in part I enables formal characterization of information systems methodologies. That is, it elaborates the meaning of ... View full abstract»

    In this paper, a model for group decision-making is proposed and defined in a linguistic context. A multiperson multicriteria decision problem is considered, in which a group of experts is involved in the evaluation of the performances of a set of alternatives with respect to a predefined set of criteria. The objective is to evaluate a consensual judgement and a consensus degree on each alternativ... View full abstract»
