    Full exploitation of available resources in a flexible manufacturing system is extremely important to optimize its productivity. The parameters on which to act in order to maximize exploitation of the resources are the sequence of activities performed by each resource and the number of parts processed in each production cycle (WIP). The aim of the paper is to propose a performance optimization str... View full abstract»

    Techniques of cartoon animation, when applied to the interface, provide the user with greater visual cues, and convey a feeling of substance to the objects being manipulated. The paper describes the effects used to animate many of the interactions in a structured graphical editor. The editor is used as a tool in a visual parallel programming environment and provides a new large application to test... View full abstract»

    It was clarified in motion detection that the analog network based on a biological system works in a similar manner to a simplified algorithm of the optical flow. The proposed network is constructed by combining simple fundamental circuits called VSC. The direction and speed of motion can be detected with the network. The network is expandable for large scale integration. A motion detection system... View full abstract»

    We aim with this research is to build an integrated environment to serve as an assistant in the educational process. When we deal with unstructured knowledge, getting of useful information for the teaching process is very difficult. Neural networks can store subsymbolic knowledge, but until recently it was believed to be only in a “black-box” format. Knowledge extraction from NNs is a ... View full abstract»

    There is a growing interest from various fields of studies in geographic information systems (GIS) which promotes efficient storage and retrieval of geographic information. The development of automated vectorizing system, an input method for GIS, is of extreme importance due to the fact that this part of constructing a GIS has been time consuming. Most vectorizing systems require users to set para... View full abstract»

    Qualitative interpretation is a process to convert numerical output of sensors into symbolic representation. This process is one of the most critical path to connect intelligent systems with real world. In this paper, qualitative interpretation is realized as pattern-based classification of time-series signal by using ART2 neural networks. As an example, automatic classification of flow patterns i... View full abstract»

    We extend the basic Bellman and Zadeh's (1970) model of multistage control (decision making) in a fuzzy environment to include both objective and subjective fuzzy constraints on controls and fuzzy goals on states at the consecutive control stages. Moreover, we consider some aggregation operators to reflect different attitudes towards the satisfaction and substitutability of the fuzzy constraints a... View full abstract»

    This paper attempts to analyse and classify different methods of fuzzy control (FC) design. It aims at providing some practical recommendations on how to design a FC and how to choose the right design method. The goal is to develop a more or less systematic procedure of a FC design which can be used as a reference. The design process can be roughly divided into two stages: an initial choice of the...

    This paper briefly discusses the existing MetaCon architecture, and its current upgrade to the ATTITUDE architecture for multi-agent, multilevel data fusion, as a motivation for formulating a tolerant approach to both procedural and declarative reasoning. Fuzzy first order logic is then formally defined before truth profiles are introduced to simultaneously accommodate ontological and epistemic un... View full abstract»

    Presents a fuzzy method for classification and recognition of separated handwritten characters. Linguistic expressions describing the individual characters are derived from a fuzzy model of a set of character samples. A small scale application of the method in which 26 lower-case cursive characters written by 30 different writers were analysed yielded 64% recognition rate. The method was also used...

    We propose a clustering method for profile data based on a genetic algorithm (GA). The GA can be considered as a flexible algorithm by setting up genetic operations and fitness function according to the problem. We propose the competitive GA considering direct competitions between individuals concerning the representative patterns for clusters. Further, we tried some specific genetic operations fo...

    Interpreting the stochastic systems in a fuzzy environment as given by Bellman and Zadeh (1970) in the frame of stochastic decision process, we present two approaches for the multi-stage stochastic decision process: one is an invariant embedding method, and the other is an a posteriori-conditional decision process View full abstract»

    A relational data model is extended under a modal logic approach so that it can deal with different kinds of imperfect information. In the extended model the imperfect information is uniformly represented in a set of possible worlds and an accessibility relation. This leads to the extended data model having the same operations to different kinds of imperfect information. Moreover, the model can su... View full abstract»

    Proposes a fuzzy ranking method to solve job scheduling problems. The proposed fuzzy ranking method is based on the concept of the center of gravity method. For each job in a job scheduling problem, the profit is transferred into the membership value, and the deadline is transferred into the value of a fuzzy element X. Then, each job can be transferred into a fuzzy number, and we can find the cent... View full abstract»

    We exploit the two distinguishing features of Boltzmann machines-plasticity of connections and concentration of equilibrium states around the minima of a loss function-for designing an optimization algorithm where the neural network learns to suitably locate its equilibrium state on the target of the optimization problem. The algorithm is structured in two loops: an inner loop catches the equilibr... View full abstract»

    Despite the enormous power of present-day computers, digital systems cannot respond to real-world events in real time. Biological systems built with very slow chemical transistors, however, are very fast in such tasks as seeing, recognizing, and taking actions. The paper will discuss what we can learn from biological computing systems and how we can implement the principle using the state-of-the-a... View full abstract»
