研究報告書
研究成果の概要（和文）：日本の製造業は，機械製品を低コストで供給する必要に迫られている．多種多様な製品を迅速に市場に投入するためには，製品の製造性などをできるだけ早い時期に評価し，製造が容易な製品を，手戻りの無駄なく設計する仕組みが重要となる．製品の製造性に関する条件の多くは，球や円筒などの基本形状を，製品の立体モデルの内部や周囲に配置する問題として統一的に評価できる．本研究では，この考え方に基づいて製品の製造性などを高速に評価する並列処理アルゴリズムの開発と，GPU （Graphics Processing Unit）を用いた処理プログラムの実装を行った．開発したプログラムを企業に提供し，実際的な性能評価も行った．研究成果の概要（英文）：Japanese manufacturing industry is strongly requested to produce products withsufficient functions in a reasonable price for new customers in emerging markets. For manufacturing suchproducts, evaluation of their producibility in early design stage is indispensable, otherwise problemsare detected in the late manufacturing preparation stages and costly re-works become necessary. We foundthat most of the constraints relating to the producibility can be evaluated in a uniformed manner byplacing simple geometric objects such as spheres, cylinders and cones in the internal side or external　side of the geometric model of the products. In this research work, we developed new parallel algorithms　for evaluating the producibility based on the concept mentioned above. We also developed parallel　processing software systems using graphics processing unit (GPU). Developed software is provided to someleading manufactures in Japan for evaluating their functions with real products.
