    A coordinated multifaceted conceptual framework for the development of real-time control software for integrated manufacturing systems is described. This orderly, rational, and structured approach is based on a blending of modern software concepts and formal semantic models. Using a common distributed language environment and generic (i.e. reusable) software, the authors construct control software... View full abstract»

    Features of expert systems applied in manufacturing design are presented. Three issues in expert systems, namely, knowledge representation, knowledge acquisition, and inference strategy, are briefly discussed. The tandem architecture of expert systems, which allows for close interaction of the inference engine with a set of models and algorithms, is outlined. Four design problems in manufacturing ...

    The adequacy of an exclusively attitudinal component model, which is analogous to the traditional decision-theoretic model, in which each option is scored and weighted on multiple attributes, is investigated. The results indicate that a purely attitudinal model is inadequate when predicting the career intentions of young people. This conclusion holds, irrespective of how the relative weights used ...

    There are many issues associated with the design and evaluation of information systems to aid real-time dynamic decision-making in environments where decision-making responsibility and knowledge bases are physically separated and potentially geographically distributed; and where there are multiple agents, each responsible for portions of the decision-making effort. There are a great many concerns ... View full abstract»

    Cited by:  Papers (12)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3946 KB)

    A qualitative approximation methodology used to design a training simulator is described. Qualitative approximation is based on a hierarchical description of dynamic systems, in which the primitives that approximate the functions of the components are at the lowest level. The primitives provide qualitative states that describe the evolution of the system. The details of the modeling methodology ar... View full abstract»

    The tasks and problem-solving methods used by an engineer in constructing a failure-management expert system from design information about the device to be diagnosed are analyzed. An expert test engineer developed a troubleshooting expert system based on device design information and experience with similar devices, rather than on specific expert knowledge gained from operating the device or troub...

  • Shafer-dempster reasoning with applications to multisensor target identification systems

    Cited by:  Papers (65)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1897 KB)

    Bayes theory is provably optimal whenever all the sensor sources are contributing information at a single Bayesian level of abstraction. Often, however, this is not the case. Shafer-Dempster reasoning is a generalization of Bayes reasoning that offers a way to combine uncertain information from disparate sensor sources with different levels of abstraction. Shafer-Dempster logic is discussed and de... View full abstract»

    Gabor function expansions are of particular interest in image analysis and understanding because they offer a means by which an image can be represented in an invariant form in both time and frequency domains. An asymptotic technique is developed for determining the coefficients of Gabor expansions. The technique overcomes some of the problems of the analytical determination of the coefficients of...

    A constructive method for the inference of regular grammars from positive sample strings of language using skeletal structure descriptions, is proposed, and polynomial-time algorithms based on the method are presented. The algorithms infer in the limit a class of regular languages, designated as terminal distinguishable regular languages. They do not overgeneralize if the samples are from a certai...

    Cited by:  Papers (19)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1913 KB)

    The character set used by the Chinese is greater in both size and complexity than that used by the Japanese, and experiments performed by the authors indicate that the stroke-matching algorithm of Yamamoto and Rosenfeld (1982) is too computationally intensive to be implemented for the recognition of complicated Chinese characters. A modified relaxation method that greatly reduces the computational... View full abstract»

    In a data communication network the message traffic has peak and slack periods and the network topology may change. When the learning approach is applied to routing, a learning automation is situation at each node in the network. Each automation selects the routing choices at its node and modifies its strategy according to network conditions. A model of a nonstationary automaton environment, with ... View full abstract»

    Statistical problems in which the available experimental observations are not necessarily exact have been described previously by means of a probabilistic-possibilistic approach based on the concept of the fuzzy information system. When Zadeh's probabilistic definition (1978) is adopted, the gain of information about the state of nature or parameter contained in a fuzzy information system and the ... View full abstract»

    PAR (principal axis representation) for rotational parts (i.e., solids of revolution) is proposed as an internal representation scheme for constructive solid geometry (CSG). They key idea of PAR is to represent an object uniquely by its principal axis and a set of boundary curves. Since PAR is in an evaluated form, geometrical properties of parts can be computed more directly and efficiently from ... View full abstract»

    A novel cost-efficient parallel and pipelined bit-serial array architecture is proposed for the computation of robot inverse dynamics. It achieves a certain bit-serial execution-time lower bound. The core of the system consists of two arrays of multifunctional bit-serial cells.

    Publication Year: 1987, Page(s):1068 - 1071
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (841 KB)

    The problem of analysis and parameter estimation by means of the Taylor operational matrix is addressed. The goals are twofold. For system analysis, variables of the deterministic bilinear system with time-varying parameters are expanded into Taylor polynomials, and the solution of a differential equation is reduced to that of a linear algebraic matrix equation. The second goal is to estimate the ... View full abstract»

    For the problem of parameter learning in pattern recognition, the convergence of stochastic approximation-based learning algorithms have been investigated for the situation in which mislabeled training samples are present. In the cases considered, it is found that estimates converge to nontrue values in the presence of labeling errors. The general m-class N-feature pattern recognitio... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1504 KB)

    A model is described that uses Boolean rule matrices that are equivalent to implication digraphs to transform truth states associated with rule conditions into deduced or abduced truth states. Such transformations realize propositional logic to deduce controls for complex real-time noninteractive systems. The algorithm runs in deterministically polynomial time and is easy to implement. The rule ma... View full abstract»

    Although the economic order quantity (EOQ) formula is probably one of the most famous formulas in the industrial management field, the composition and estimation of the cost parameters have always been vague and imprecise at best. In view of the inherently fuzzy aspect of the cost determination, the EOQ formula is reexamined in a fuzzy-set-theoretic perspective. An introduction to fuzzy systems th... View full abstract»

    A unified approach for comparing the performance of fuzzy and nonfuzzy controller designs is presented. Relationships are established between the gain parameters for the two classes of controller designs. The methods presented apply equally well to proportional-plus-integral, linear multiband, and multilevel relay controllers. View full abstract»

    A reinforcement scheme that is based on the linear reward-inaction updating algorithm is presented for a learning automaton whose action set changes from instant to instant. A learning automaton using the algorithm is shown to be both absolutely expedient and ε-optimal. The simulation results verify the ε-optimality of the algorithm. The results can be extended to the design of gener... View full abstract»
