抄録	In this paper, we studied a planning and scheduling of production system considering demand changes. In the proposed system, planning part determines lot-size and amount of jobs in production. On the other hand, scheduling part determines the production sequence of jobs. In order to treat with the demand changes, both planning and scheduling should work well simultaneously. In the proposed system, preset and real time production control system is newly constructed from the view point of adaptive control. In the system, production planning is modified when the difference between production amount and demand becomes large. Moreover, production schedule is regenerated when the determined schedule is deviated from the prospected one. The scheduling system is characterized as the autonomous decentralized optimization system where each job works as agent and agent searches its appropriate starting time of processing. The effectiveness of the proposed system is confirmed by numerical examples.

Automatic Detection of Circular Objects by Ellipse Growing

JaLCDOI	10.18926/47004
フルテキストURL	mfe_36_1_107_116.pdf
著者	Kanatani, Kenichi\| Ohta, Naoya\|
抄録	We present a new method for automatically detecting circular objects in images: we detect an osculating circle to an elliptic arc using a Hough transform, iteratively deforming it into an ellipse, removing outlier pixels, and searching for a separate edge. The voting space is restricted to one and two dimensions for efficiency, and special weighting schemes are introduced to enhance the accuracy. We demonstrate the effectiveness of our method using real images. Finally, we apply our method to the calibration of a turntable for 3-D object shape reconstruction.

Robust Image Matching under a Large Disparity

JaLCDOI	10.18926/46970
フルテキストURL	mfe_37_1_025_032.pdf
著者	Kanazawa, Yasushi\| Kanatani, Kenichi\|
抄録	We present a new method for detecting point matches between two images without using any combinatorial search. Our strategy is to impose various local and non-local constraints as "soft" constraints by introducing their "confidence" measures via "mean-field approximations". The computation is a cascade of evaluating the confidence values and sorting according to them. In the end, we impose the "hard" epipolar constraint by RANSAC. We also introduce a model selection procedure to test if the image mapping can be regarded as a homography. We demonstrate the effectiveness of our method by real image examples.

Toyota dans l'histoire

抄録	At the end of the 20th century, the Japanese automobile industry is suffering from the long depression of Japanese economy to such an extent that sorne of Japanese carmakers were not able to survive without cooperating with foreign powerful carmakers. Nissan has been in restructuring under the French managers dispatched by Renault. Suzuki and Isuzu began to reinforce their cooperation with GM, whereas Fuji Heavy Industry (Subaru) and Mitsubishi are searching for their Western partners. It is only Toyota and Honda that seem to be able to compete by themselves on globalized automobile markets. Irony of the history, because until the end of the 1980s all Japanese carmakers were regarded as the most competitive companies of the world by incarnating the 'Lean Production' model whose basic model is the Toyota Production System. This stereotype has to be dismissed, because they have been having neither the same management nor the same strategy. This paper then tries to show the history of Japanese automobile industry from its very beginning to mid-1990 when the majority of carmakers are facing a crisis. In doing so, it presents the specifie characteristics of Toyota by placing it in the historical perspective.

タイトル（別表記）	The Evolution of Industries and the Public Policies for the Creation of New Business
フルテキストURL	oer_032_4_065_100.pdf
著者	新田光重\|
抄録	In the latter half in 1990's, the extensive public policies for promoting newly establishment of the enterprise (for example, "Law for facilitating the creation of New Business" enforced in 1999) were introduced in Japan. In this paper, I would like to search the theoretical background of such policy as the policy for promoting evolution of industry that the innovative activities were accompanied by newly establishment and discontinuance ofbusiness of the enterprise. To begin with, I carried out the fact finding on the relation between newly establishment and discontinuance of business using the data of "The 1999 Establishment and Enterprise Census." And I verified some hypotheses on the evolution of industries which Acs and Audretsch (1991) and Audretsch (1995) presented and tried the reexamination of these hypotheses. I set the increasing rate of newly establishment (the number of employee base) and the increasing rate of discontinuance of business (the number of employee base) during 1996-1999 period as main variables. I carried out the regression analysis on manufacturing industries and service industries (industrial classification of 2 and 3 digits), and confirmed that there was the positive correlation between the increasing rate of newly establishment and the increasing rate of discontinuance of business. I examined the ratio of increasing rate of discontinuance of business and increasing rate of newly establishment (D / E ratio) on enterprise scale (by the number of employee base) and industrial sector (industrial classification of 2 digits). As the result, I confirmed that the D / E ratio described the V-shaped curve with the extension of enterprise scale in many industrial sectors. I consider that the base point of this V-shaped curve shows minimum efficient scale. I confirmed that there was the positive correlation between this minimum efficient scale (D / E ratio at V-shaped base point) and employment increasing rate of the industrial sector. Based on these results of analysis, I describe some policy implications on the public policies for the newly establishment of enterprises and the initial support and growth support for the newly-established and smallscale enterprises.
