Mode Analysis of Pareto-Optimal Design

本研究的目的是建立模式分析的帕累托最优设计（MAPOD）框架。在本研究中，三目标设计优化问题的MAPOD框架已经开发并在现实世界的设计问题上进行了演示，即，太阳观测航天器的多目标轨道设计优化问题。为了将MAPOD应用于三目标设计优化问题，使用三个目标中的两个将帕累托最优设计绘制为散点图，其中每个图的颜色表示其特征向量值。对于四个或多个目标的设计优化问题，将自组织映射与该方法相结合，结果表明了MAPOD对实际设计优化问题的有效性。这项研究将有助于日本的设计创新。

Objective of this study is to establish the mode analysis of Pareto-optimal designs (MAPOD) framework. In this research, MAPOD framework for three-objective design optimization problem has developed and demonstrated on a real-world design problem, i.e., a multiobjective trajectory design optimization problem of solar observatory spacecraft. To apply MAPOD to a three-objective design optimization problem, the Pareto-optimal designs are plotted as a scatter plot using two of three objectives where color of each plot indicates its Eigen vector value. For four or more objective design optimization problem, self-organizing map is coupled with this approach.There result show effectiveness of MAPOD for real-world design optimization problems. This research will contribute to design innovation in Japan.
