パレート最適解情報に基づく使用環境に対するフレキシビリティを考慮した最適設計

抄録

This paper presents design decision-making methods considering flexibility for a working environment. In order to make a clear evaluation of the changes of the most preferable levels of the product performance and product manufacturing cost due to changes in the working environment (flexibility conditions), three objective design optimization problems are constructed having the three objectives of maximization of the product performance, minimization of the product manufacturing cost and maximization of flexibility for working environment. The Pareto optimum solution set forming a curvature is obtained. Then, a decision-making method for determining the preferable design solution using information from the Pareto optimum solution curvature is presented. Finally, the proposed methods are applied to design examples for demonstrating effectiveness.
