人が自分の夢を描き、その夢の実現に向かって自分が変容していくことは、幸せを実現していくうえで普遍的な願いである。また、このように自分の源とつながった個人が、自分の内側にある関心に従って、あるテーマのもとに新しく集い、共創的な活動を通じて自己変容しながら大きな目的を達成していく。このような融通無碍な生命的なチーム、組織やコミュニティのありかたが、これからの社会でより重要な役割を果たしていくと考えられる。 本論文では、このように一人一人が自分の内発的動機に基づき、自己組織化的にチームが形成され共通目的が達成されていくプロセスに焦点を当てたチームの自己組織化モデルを提案する。さらに提案したチームの自己組織化モデルを用いて、子どもたちにオンラインで絵本の読み聞かせ体験を提供するオンライン絵本会の活動...

概要 個人、チーム、組織が抱く夢の実現や変容、内省などのモデルとして、U理論、行動探求、成人の発達理論などが提案されている。しかしながらこれらの理論やモデル間の相互関係は必ずしも明確に議論されてこなかった。本論文ではこれらのモデルの相互関係を統合的に俯瞰するための参照モデルを提案する。これにより、これらの方法論を統合的に理解するための基本的なフレームワークを提供する。 Abstract Theory U, Action Inquiry, Adult Development Theories, etc. are proposed as models of realization, transformation and introspection for individuals, teams,...

Theory U, Action Inquiry, Adult Development Theories, etc. are proposed as models for realization of dreams, transformation and reflection for individuals, teams, organizations. However, the relationships among these theories and models have not necessarily been clearly discussed. In this paper, we propose an integrated reference model called IRMDT...

古典的なマーケティング理論に基づく経営においては、新製品や新サービスの機会は発見されるものであり、新市場は満たされていない潜在的なニーズを探索し、目的とするセグメントを選択する立場をとっている。このアプローチはコーゼーション論理と呼ばれる。これに対しサラスバシーらによって提案されたエフェクチュエーション論理においては、熟達した起業家は、手段からスタートし、「これらの手段を使って何ができるだろうか?」という問いを自分に投げかける。すなわち手段から目的をデザインする。 また、企業がベンチャーから中堅企業、大企業に発展する過程では、熟達した起業家や経営者はエフェクチュエーション論理とコーゼーション論理を巧みに組み合わせて活用し意思決定をしている。 本論文では、このような熟達した起業家や経営者が効果...

オットー・シャーマーによって提唱されているU 理論[1],[2]は、創造する人の意識の内面や視点の移動に 焦点をあてて創造活動をモデル化している。一方、実際の創造活動においては創造する対象分野のドメイ ン知識を駆使して発散、収束、評価を繰り返していると思われるが、U理論自身ではこれらのドメイン知識 そのものの記述言語については言及していない。 また、デザイン思考やシステム思考、およびこれらを統合したイノベーティブ思考[3]においては、インサイ ト発見のための発散、収束、評価を行うための種々の創造技法や表現ツールが利用されている。 本発表 ではこのUプロセスとイノベーティブ思考を融合し、創造活動を実施している際の思考過程を詳細にモデル 化する手法VMUK(Visualization Model...
Conference Paper
One of the most useful applications for an optical disk is a digital still camera (DSC). It is widely recognized that the vibration/shock caused by the motion of these devices is a serious problem for a portable CD (compact disk) or MD (mini disk) player. As far as a DSC with a recordable optical disk is concerned, if is far more important to reduc...
Conference Paper
Disturbance rejection is becoming more and more important as optical disk players are being utilized in more applications. The paper considers the design of a tracking servo controller for a CD player using the disturbance observer (DOB) theory. By adding a DOB to the conventional PID controller, the tracking performance is dramatically improved in...

In digital communication systems, a linear transversal equalizer was applied to signal equalization. But because of the nonlinearity of the equalization problem, it was desirable to incorporate some nonlinearity in the adaptive equalizer structure. We considered the application of the radial basis function (RBF) network to the adaptive equalizer an...

Fuzzy logic, neural networks, and neuro fuzzy technology are now regarded as effective methods for realizing intelligent industrial systems and consumer electronic products. Furthermore, a novel paradigm, «chaos engineering», is expected to become another key technology for various applications such as nonlinear prediction of time series, nonlinear...
Article
Since deterministic chaos is not only a profound concept in science but also a ubiquitous phenomenon in real-world nonlinear systems, extending to a variety of temporal and spatial scales, it can be naturally related to applications in science and technology [4]. In fact, it is not difficult to find the buds of such possible applications in histori...
Article
Several algorithms have been proposed to identify a large scale system, such as the neuro-fuzzy GMDH, and the fuzzy modeling using a fuzzy neural network, As another approach, Sanger proposed a tree-structured adaptive network. But in Sanger's network, it is not clear how to determine the initial disposition of bases and the number of bases in each...
Article
In this paper, we apply the self-generating radial basis function network (SGRBF) to the dimension analysis of the nonlinear dynamical systems including chaotic time series. Firstly, we formulate a nonlinear time series identification problem with a nonlinear autoregressive moving average (NARMAX) model.Secondly, we propose an identification algori...
Conference Paper
In this paper, we propose a new identification method called "Adaptive Tree-Structured Self Generating Radial Basis Function(ATree-RBF) ". In this method, we combine the Sanger's tree-structured adaptive network for overall model structure, with the Maximum Absolute Error(MAE) selection method for sub-tree identification problem.
Article
So far, several fuzzy modeling methods such that parameters of the fuzzy model are tuned using gradient method have been proposed. But the problem in these methods is that the constraints on the shape parameters of the membership functions are not considered explicitly. To solve this problem, in this paper, we firstly formulate the original fuzzy m...
Conference Paper
In this paper, we analyze the learning ability of various design methods for radial basis function network, especially for function approximation problem. We consider the three methods; the k-means clustering algorithm by Moody and Darken (1989), the orthogonal least squares method by S. Chen et al. (1991), and the maximum absolute error selection...

In recent years, intelligent industrial systems and consumer electronic products are widely and intensively developed. Fuzzy logic, neural network, and neuro & fuzzy technology which integrates these approaches are now regarded as an effective method to realize such intelligent features. Furthermore, a novel paradigm, “chaos engineering”, is now ex...
Conference Paper
The authors propose a self-generating algorithm for radial basis functions to automatically determine the minimal number of basis functions to achieve the specified model error. This model is also regarded as a multilayered neural network or fuzzy model of class C<sup>∞</sup>. The self-generating algorithm consists of two processes: model parameter...
Article
This paper concerns a static multi-objective control problem of the distributed parameter system, in which regionally decentralized plural decision-makers carry out control actions based on their own goals. The problem is formulated as minimization of vector functional to generate noninferior controls. Optimality conditions are derived. Moreover, w...
Article
This note is concerned with the generalization of Farkas'' theorem of the alternative and its application to derive the necessary optimality conditions for min-max problems with satisfaction conditions. Farkas'' theorem is generalized to a system of linear inequalities with max operations. The problems studied require a solution at which the worst...
Article
This paper discusses the static multi-object control problem for a distributed system in which more than one geographically distributed decision-maker (control station) performs control based on their own object functions. The object function of the control station is given in an integral form, with the range of integration being limited to an inte...
