IEEE International Conference on Fuzzy systems (FUZZ-IEEE)

Traditional methods for diagnosis/prediction of plant abnormality rely on the acquisition of fragmentary knowledge or rules from experts and the application of the state vectors of plant to portions of the knowledge or rules thus obtained to derive a conclusion. Therefore as the complexity of the plant to be evaluated increases, the degree of uncertainty of knowledge obtained from experts increases and thus the accuracy of evaluation decreases. To solve this problem, this paper proposes an intelligent alarm method which uses a fuzzy integral model based on fuzzy measure that can provide an accurate model of human subjective evaluation mechanism. The intelligent alarm method is unique in that it can quantify the uncertainty of the information to be evaluated and of human being who evaluates. To achieve these objectives, this paper provides a simulation of the expert's overall plant evaluation by using an "interpretation of plant state based on expert knowledge" and a "overall judgement of plant state which amplifies the essence of the state interpretation information". The method was applied to the prediction of abnormality for a drying process of a chemical plant to demonstrate that abnormality prediction by a simulation method is possible, that even for a plant without abnormality the method can provide estimate of the potential of abnormality, and that the method is useful in alleviating the burden of the monitoring and checking work for plant.< >

The method of "state interpretation by fuzzy memory-based reasoning" and the identification method of "fuzzy measure and scenario integrated evaluation scale" are proposed to construct the intellectual evaluation considering the context. Conventional methods evaluate the object by interpreting the state according to fragmentary knowledge acquired from experts. The interpretation, however, often depends on contexts, that is, other states that exist at the same time. The problem is that the evaluation result has been ambiguous in the usual knowledge representation because the interpretation of the state does not change even if the context changes. The method of interpreting the state by fuzzy memory-based reasoning proposed eliminates the fuzziness by using the bottom up and the top down processing mutually to reorganize the information so that the state suits its strategy, or its context. The method of identifying fuzzy measure proposed clarifies indirect intentions, or nonlinear relation between the state and the strategy based on the appropriate context information, which eliminates the ambiguity included in the state evaluation. Furthermore, these methods are applied to the adjustment of the cooling capability in a vending machine.< >

The major problem in making fuzzy control a reality is designing and adjusting the control rules. In process control, it is impossible to get complete informations for the design because of remaining unexplained characteristic and change of it. So, we developed a design adjustment and evaluation method of the control rules and membership functions based on operator's judgments and process data. This paper reports on the method and its effectiveness.< >

A Holonic Manufacturing system (EMS)is a manufacturing system where key element, such as machines, products, park, etc., have artonomous and cooperative properties. These element are called "holons" a word coined by combining "holos" (the whole) and ‘onu (a particle) following Koestler. In an HMS, each "holos" activities are determined through cooperation with other holons, as opposed to being determined by a centralized mechanism. An EMS could therefore enjoy high agility, which is an important characteristic for future manufacturing systems. Effective cooperation of holons for overall system performance, however, is mostly an open issue. In the paper, the holonic concept is applied to a simple robotic assembly testbed, and cooperation mechanism among holons for planning and schedukng are established, respectively, baaed on an adaptive consistency algorithm and the Lagrangian relaxation technique. It turns out that Lagrangian relazation provides a theoretical,foundation for the cooperation of scheduling activities among holons. The system has been implemented in object-oriented framework, and evaluated based on the computation times for generating assembly plans and scheduler and the quality of schedules under different circumstances. Preliminary testing showed that the system can generate assembly plans and high quality schedules, and respond to dynamic changes. © 1994 IEEE.

There is a very large demand for basic telephone service in developing nations, and remote parts of industrialized nations, which cannot be met by conventional wireline and cellular systems. This is the world's largest unserved market. We describe a system which uses recent advances in active phased arrays, fast-packet switching technology, adaptive routeing, and light spacecraft technology, in part based on the work of the Jet Propulsion laboratory and on recently-declassified work done on the Strategic Defense Initiative, to make it possible to address this market with a global telephone network based on a large low-Earth-orbit constellation of identical satellites. A telephone utility can use such a network to provide the same modern basic and enhanced telephone services offered by telephone utilities in the urban centres of fully-industrialized nations. Economies of scale permit capital and operating costs per subscriber low enough to provide a service to all subscribers, regardless of location, at prices comparable to the same services in urban areas of industrialized nations, while generating operating profits great enough to attract the capital needed for its construction. The bandwidth needed to support the capacity needed to gain these economies of scale requires that the system use K(alpha)-band frequencies. This choice of frequencies places unusual constraints on the network design, and in particular forces the use of a large number of satellites. Global demand for basic and enhanced telephone service is great enough to support at least three networks of the size described herein. The volume of advanced components, and services such as launch services, required to construct and replace these networks is sufficient to propel certain industries to market leadership positions in the early 21st Century.

Intention recognition using conceptual fuzzy sets

Intention recognition using conceptual fuzzy sets

IEEE International Conference on Fuzzy systems (FUZZ-IEEE)

In the man-machine interface, the user's goal is transmitted to the system, the system understands the goal, and the processing is carried out. The status of the system and the processing result are transmitted to the user. Therefore, to realize this communication, it is necessary to recognize a user's intention from his or her words. This intention recognition raises the computer system to the information processing level of a human. A conceptual fuzzy set (CFS) represents the context-dependent meaning of a vague concept. Multilayered reasoning (MLR) based on CFS can provide abstract and concrete representation simultaneously, and can handle top-down and bottom-up processing simultaneously. The authors apply MLR based on CFS to intention recognition. Goal recognition for a drawing tool is used as a concrete example. The multistructured knowledge for goal recognition is represented using CFS, and is inductively constructed using the Hebbian learning law.< >

A postprocessing algorithm for Japanese OCR based on the probabilistic and semantic method is described. It determines the reliability of each recognized character and word in OCR outputs with their recognition probability and appearance frequency in the text. Using these reliabilities, grammatical word paths are searched in each phrase. When it is necessary to select the most suitable word from a similar word set, an attempt is made to select a particular one by the semantic method with co-occurrence word dictionary. This method was applied to OCR outputs of current newspapers and technical documents including some unregistered words, and evaluated its performance. While error correction rate depends on the ratio of unregistered words in the texts, the error detection rate is almost 90%.< >

A valuable technique during concept development is rapid prototyping of software for key design components. This approach is particularly useful when the optimum design approach is not readily apparent or several known alternatives need to be rapidly evaluated. A problem inherent in rapid prototyping is the lack of a "target system" with which to interface. Some alternatives are to develop test driver libraries, integrate the prototype with an existing working simulator, or build one for the specific problem. This paper presents a unique approach to concept development using rapid prototyping for concept development and scenario-based simulation for concept verification. The rapid prototyping environment, derived from artificial intelligence technology, is based on a blackboard architecture. The rapid prototype simulation capability is provided through an object-oriented modeling environment. It is shown how both simulation and blackboard technologies are used collectively to rapidly gain insight into a tenacious problem. A specific example will be discussed where this approach was used to evolve the logic of a mission controller for an autonomous underwater vehicle.
