Creation of Design-Informatics - for Materialization of next-generation innovative aerospace Vehicle

设计信息学是一种创新的设计方法论。设计信息学有三个要点：(1)多学科设计优化方法的进步；(2)利用信息挖掘的设计空间的结构化和可视化；(3)在大规模和真实世界的航空设计问题中的应用。在(1)领域中，基于差分进化/遗传算法进化的混合方法对于有噪声的标准测试问题具有很大的优势。在(2)领域中，给出了自组织映射、方差分析、粗糙集理论和决策树的描述。在(3)领域，利用设计信息学设计了无声超音速技术演示器，并利用设计信息学研究了混合动力火箭问题和基于仿生学的环保型创新飞机构型。

Design-Informatics which is an innovative design methodology has been proposed. Design-Informatics has three points as (1) the advancement of the manners for multidisciplinary design optimization, (2) the structuring and visualizing of design space using information mining, and (3) the application to large-scale and real-world aeronautical design problems. In (1) field, differential evolution/genetic algorithm evolutionary-based hybrid method has been advantageous for the standard test problems with noise. In (2) field, the specifications of a self-organizing map, analysis of variance, rough set theory, and decision tree has been shown. In (3) field, the silent supersonic technology demonstrator has been designed by using design-informatics, and then a hybrid rocket problem and a biomimetics-based configuration for environmental-friendly innovative airplane are also considered by using design-informatics.
