    The objective of this paper is to demonstrate how fuzzy dynamic systems can show chaotic phenomena and chaotic dynamics similar to those found in a class of nonlinear systems. We found that the fuzzy chaotic dynamic model of a cubic map results in the same bifurcation diagrams, and that it shows stable equilibrium points, period-doubling and chaotic attractors View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (396 KB)

    New development planning areas, like new towns and new communities, usually ignore the layout of location for emergency facilities, like police station, hospital and fire station, beforehand. Such remissness is harmful to people's life and property. We adopt the ideal of backup coverage to expand the BACOP1 model to the BACOP1-m model with m+1 objectives in the 0-1 integer programming model to ana... View full abstract»

  • The study of automatic insertion and deletion of fuzzy rules in fuzzy neural network models

    Publication Year: 1996, Page(s):248 - 253
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (256 KB)

    This research is based on a fuzzy neural network, named knowledge-based neural network with trapezoid fuzzy set inputs (KBNN/TFS). We use this network model to refine fuzzy rules with a training database. We propose an interactive consistency checking engine with automatic rule insertion and deletion (ICE/RID) to perform fuzzy rule verification. This process is used to verify the initial rule base...

  • Fuzzy multisets

    Publication Year: 1996, Page(s):429 - 434
    Cited by:  Papers (5)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (252 KB)

    We propose a design based on extending the notion of a fuzzy set to a fuzzy multiset. As the concept of fuzzy set is itself a generalization of a standard set notion, any further generalization should be carefully motivated. We concentrate on two reasons, the first one being the continuity of the fuzzy arithmetic, the other a virtual necessity for the otherwise elaborate structures in approximatin... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (224 KB)

    Hyperthermia is known to be a method of killing tumor cells by heating. An ultrasound transducer is often used as the heating device. In order to kill the tumor cells and not injure the normal tissue, the temperature distribution generated by the ultrasound must be predetermined. For a multi-element ultrasound transducer, the phase and the amplitude of the input signal for each element can be tune... View full abstract»

    Fuzzy reasoning and fuzzy logic are two related but different research fields such that both are fruitful but have not yet been well linked. The aim of the paper is to: (i) prove that it is impossible to keep all theorems in classical propositional calculus to be tautologies in fuzzy propositional calculus; (ii) establish a so called quasi-formal deduction system and prove the corresponding soundn...

  • On rough and LT-fuzzy sets

    Publication Year: 1996, Page(s):13 - 17
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (200 KB)

    A concept of LT-fuzzy sets was introduced by Rasiowa and Cat Ho (1992). LT-fuzzy sets are a modification of L-fuzzy sets introduced by Goguen (1967). We introduce here a notion of a generalized rough set and show that it can be considered as a particular case of a L-fuzzy set. We also generalize the notion of a rough equality of sets, introduced by Pawlak in 1985 to a notion of topological equalit... View full abstract»

  • A proposal of fuzzy ID3 with ability of learning for AND/OR operators

    Publication Year: 1996, Page(s):24 - 29
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (204 KB)

    The fuzzy ID3 is a powerful method to acquire fuzzy decision trees. However, the fuzzy ID3 has a couple of problems, i.e., a problem of a lack of representation and an adjusting problem. In our fuzzy ID3, AND/OR operators are formulated using t-norm and t-conorm connectives with parameters and each parameter is adjusted using golden section method. By adjusting parameters, the proposed fuzzy ID3 g... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (208 KB)

    The user equilibrium in traffic assignment problem is to choose the minimum cost path between every origin-destination pair. In this study, we consider the infeasible user equilibrium in traffic assignment problem. That is, there does not exist any solution of the problem. We are interested in the minimum degree of relaxation needed so that the problem can exist with at least one solution. Therefo... View full abstract»

  • A new encoding method of genetic algorithms towards parameter identification of fuzzy expert systems

    Publication Year: 1996, Page(s):406 - 411
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (376 KB)

    The membership functions of fuzzy expert systems need a systematic, self-learning method instead of a subjective tuning method in order to increase the performance of the fuzzy model. The genetic-algorithm learning method is consequently employed. The rule-based encoding scheme would bring the redundant information for the genetic algorithm by repeatedly representing the similar membership functio... View full abstract»

    The major problems of uninterruptible power supply (UPS) with three phase PWM inverter arise from unknown nonlinear loading to and phase couplings of the inverters. In this paper, an adaptive fuzzy control is proposed to solve these problems. The control objective is to track the desired sine waveform regardless of the versatile nonlinear loading, whose bound can be represented by a fuzzy rule-bas... View full abstract»
