Patent number: 6456989Abstract: The present invention relates to a data processing system in a hierarchical network configuration for executing applicable data processes in a comprehensible and executable form. An object of the present invention is to allow data processing capabilities to be established with high precision in a short time based on a fuzzy-neuro-integrated concept. A fuzzy model is generated by a data processing system in the form of membership functions and fuzzy rules as technical information relating to a control target. According to this fuzzy model, a weight value of the connection between neurons is set and a pre-wired neural network is established. Then, the data of the control target are learned by the neural network. The connection state and a weight value of the neural network after the learning enable tuning of the fuzzy model.Type: GrantFiled: February 22, 1999Date of Patent: September 24, 2002Assignees: Fujitsu Limited, FFC LimitedInventors: Akira Kawamura, Ryushuke Masuoka, Yuri Owada, Kazuo Asakawa, Shigenori Matsuoka, Hiroyuki Okada
