111 分散環境下における協調設計フレームワークの構築  [in Japanese] A Framework for Collaborative Design Optimization in Distributed Environments  [in Japanese]

As products become progressively more complex, the design of their mechanical systems requires knowledge of an increasingly large number of design disciplines. The design and manufacture of such high performance and high quality products has made it necessary to partition the mechanical design problem into multiple components and distribute design tasks across multiple disciplines that also support concurrent optimization. To provide a globally optimal design requires effective information exchange between the design section that are responsible for each component. Therefore this paper proposes a collaborative design optimization method for distributed environments, where each section's optimization process maintains its autonomy while enabling the constructive exchange of design solutions between sections that ultimately leads to an optimal design. Several information exchange schemes are proposed and applied to the design optimization problem for a platform type of Space Station. A comparison of information exchange schemes is followed by discussion of the effectiveness of various design environments.
