이산공간에서의 구조물 설계시 교호작용에 대한 연구

Abstract

The design of experimcnt(DOE) is getting more attention in the engineering community since it is easy to understand and apply, Recently, engineering designers are adopting DOE with orthogonal arrays when they want to design products in a discrete design space. In this research, a design flow with orthogonal arrays is defined for structural design according to the general DOE. The design problem is defined as a general structural optimization problem. Sensitivity information is evaluated by the analysis of variancc(ANOVA)» and an optimum design is determined from analysis of mcans(ANOM). Interactions between design variables arc investigated to achieve additivity which should be valid in DOE. When strong interactions exit, a method is proposed. Some methods to consider the problem are suggested.
