    The evolution of systems engineering and information technology is discussed. It is argued that there is a very important role for universities in contributing to the productivity improvements made possible by the confluence of the emerging informatics knowledge base in these areas. Internal and external changes, each associated with knowledge transfer, will be required in order to realize these n... View full abstract»

    Distributed problem-solving is defined as a subfield of artificial intelligence that deals with the interaction of groups of intelligent agents attempting to cooperate to solve problems. A taxonomy of distributed artificial intelligence systems is presented, based on the communication and control methodologies used by their constituent agents, along with the theoretical foundations which underly t...

    Probability encoding is the process of extracting and quantifying subjective judgments about uncertain quantities. In the early 1970s, the Decision Analysis Group at SRI International recommended a formal process for probability encoding based on a structured interview between a trained interviewer and the subject. Additional methods have been developed for processing encoded probabilities to faci... View full abstract»

    Direct comparisons were made of expert highway engineers' use of analytical, quasirational, and intuitive cognition on three different tasks, each displayed in three different ways. Use of a systems approach made it possible to develop indices for measuring the location of each of the nine information display conditions on a continuum ranging from intuition-inducing to analysis-inducing and for me...

    Quality control and cognitive mapping methods are combined to reduce the deficiencies of current techniques for designing exception-reporting systems for ill-structured decision problems. The approach is tested using ten managers faced with the need of evaluating the performance of their subordinates. The results are very encouraging: the information system detected over 97% of the exceptions and ... View full abstract»

    It is argued that many applications of expert-system and decision-support-system technologies will require an appropriate blend of the features of each of these technologies. Such a system is termed a knowledge support system. One of its inherent characteristics is that the knowledge will come from multiple sources and perspectives and will be inherently uncertain, imprecise, incomplete, inconsist... View full abstract»

    S. Zionts and J. Wallenius (1976) have discussed how their method for interactive multiple-objective linear programming can be extended to handle pseudoconcave utility functions. They do not, however, specify how an implied interactive search over faces of the simplex is to be done. E. Jacquet-Lagreze and J. Siskos (1982) have introduced the idea of approximating a utility function by a piecewise-... View full abstract»

  • Automatic grasping: An optimization approach

    A method is introduced for locating stable grasps with articulated mechanical hands. A metric called the grasp goal function represents the `distance' to an unstable grasp for a given position, external load, and set of joint torques of the gripper. The process of locating a stable grasp is treated as an optimization problem for which the most stable grasp is found by maximizing the grasp goal fun... View full abstract»

    The use of measures of entropy for evaluating human supervisory control performance in a flexible manufacturing system is described. The measures are especially useful in explaining performance when graphic displays intended for enhancing human pattern-recognition capabilities are available and under task conditions with contrasting types of workload.

  • Nuclear balance and the parity index: The role of intangibles in decisions

    An approach to understanding and assessing issues concerning arms control is presented. Arms control has two main objectives: (1) decreasing the possibility of a nuclear exchange; and (2) limiting the scope and intensity of such an exchange. A framework is presented for dealing with those issues relevant to the nuclear balance problem that is the central issue of arms control. A parity index is de... View full abstract»

  • Imaging black boxes with multiple stochastic output

    Publication Year: 1987 , Page(s): 828 - 833

    A black box is modeled by decomposition into an unknown but finite number of independent noise sources and of independent signal sources. Signal sources carry signals in strict relation to an input signal vector. Output signal vectors are transformable into a system-state vector by means of stochastic properties of an assembly of independent noise sources. By proper scaling such system-state vecto...

  • Improved management decisionmaking using optimization of a nonlinear mixed-integer financial model

    A nonlinear mixed-integer financial model and optimization algorithm are described that support management decisions for one defense contractor. Counterintuitive insights have been uncovered that improve financial performance at less cost and with greater confidence than traditional alternatives. It is argued that normal search routines would have been unlikely to uncover these insights. View full abstract»

    A novel interpretation of union, intersection, and inclusion in fuzzy sets in the light of measure theory is given. The existing definitions of these operators are based only on the value of membership functions characterizing fuzzy sets. The proposed definitions take into account the nature (behavior) of the membership functions together with their values. The uniqueness of the proposed definitio... View full abstract»

  • CGT: A fast thinning algorithm implemented on a sequential computer

    An approach called contour generating is proposed to reduce drastically the running time for parallel thinning algorithms on a sequential computer by providing extra storage space. The time complexity of a parallel thinning algorithm using this technique is proportional only to the object area of the image instead of the product of the whole image area and the maximum half-width of the object.

    The possibility-probability-granule approach to reasoning with uncertain information is reviewed. The unifying aspect of this approach is discussed, and its generality is extended by indicating how to represent and reason with relations between variables that are captured by transition matrices.

    Two algorithms are described for automatic image segmentation using a homogeneity measure and a contrast measure defined on the co-occurrence matrix of the image. The measure of contrast involves the concept of logarithmic response (adaptability with background intensity) of the human visual system. Provisions are made in two different ways to remove the undesirable thresholds. The effectiveness o... View full abstract»

    Learning behaviors of hierarchical structure stochastic automata are considered in a nonstationary multiteacher environment. It is shown that an extended form of an algorithm proposed by M.A.L. Thathachar and K.R. Ramakrishnan (1981) ensures absolute expediency under some conditions. As a practical application of hierarchical structure stochastic automata, intelligent behavior is considered of rob... View full abstract»

    A counterexample to the original incorrect convergence theorem for the fuzzy c-means (FCM) clustering algorithms (see J.C. Bezdak, IEEE Trans. Pattern Anal. and Math. Intell., vol.PAMI-2, no.1, pp.1-8, 1980) is provided. This counterexample establishes the existence of saddle points of the FCM objective function at locations other than the geometric centroid of fuzzy c-partition spac... View full abstract»

    A method for hierarchical decomposition of Petri net languages is proposed. The method provides a hierarchical structure of a dynamic system if the system is modeled by a Petri net and its initial state is given. The method can be used in analyzing the dynamic behavior of systems. View full abstract»
