  • Approximate optimization has become popular in engineering field such as MDO and Crash analysis which is time consuming. To accomplish efficient approximate optimization, accuracy of approximate model is very important. As surrogate model, Kriging have been widely used approximating highly nonlinear system . Because Kriging employs interpolation method, it is adequate for deterministic computer simulation. Because there are no random errors and measurement errors in deterministic computer simulation, instead of classical DOE ,space filling experiment design which fills uniformly design space should be applied. In this work, various space filling designs such as maximin distance design, maximum entropy design are reviewed. And new design improving maximum entropy design is suggested and compared.

  • 현재까지 실험을 설계하는 방법은 설계자에 의해서 시행착오(trial and error) 방식으로 하는 것이 대부분 이였으나 이 방법은 경험상으로 알고 있으며, 유효하다고 생각되는 조건하에서 여러 가지 경우의 것을 시뮬레이션 해보고 그 중에 가장 타당하다고 생각되는 것으로 결정하게 된다. 이들은 다소 경험적인 것이라 할 수 있다. 하지만 실험계획법(Design of Experiments)은 특성에 영향을 미치는 여러 가지 인자를 선정하기 위해, 또 이들의 관계를 알아보기 위한 실험을 실시하여 제품의 최적 제조조건을 경제적으로 찾아내는 기법이다. 본 연구에서는 실험계획법을 사용하여 유량을 최적화하는 요인을 선정, 얻어진 데이터를 통계적 방법으로 분석하여 최적의 조건을 나타내었다.

  • Design of experiments (DOE) is a method that has been applied in the industry to improve value for many decades. This study provides an overview of 115 cases of statistical DOE applications in the field of chemical engineering. All cases were published in important scientific journals for the last ten years. The applied design type, the experiment size, the number of factors and levels affecting the response variable, and the area of application for the design were all analyzed. Obviously, the number of publications related with statistical DOE increased over time.

  • Bayesian experimental design is a useful concept in applied statistics for the design of efficient experiments especially if prior knowledge in the experiment is available. However, a theoretical or numerical approach is not simple to implement. We review the concept of a Bayesian experiment approach for linear and nonlinear statistical models. We investigate relationships between prior knowledge and optimal design to identify Bayesian experimental design process characteristics. A balanced design is important if we do not have prior knowledge; however, prior knowledge is important in design and expert opinions should reflect an efficient analysis. Care should be taken if we set a small sample size with a vague improper prior since both Bayesian design and non-Bayesian design provide incorrect solutions.

  • In this paper, the characteristics of receiving voltage sensitivity about acoustic package in towed array sonar is analyzed through the numerical simulation and design of experiments. Simulation results show that the variation of receiving voltage sensitivity is caused by the structural resonance mode shape on baseline acoustic package. The effect of design parameters of the acoustic package are analyzed through the design of experiments to reduce the deviation of receiving voltage sensitivity. A change of hydrophone shield can thickness (t) is the greatest effect on the deviation of receiving voltage sensitivity. As a result of water tank test, the acoustic package derived from the design of experiments has reduced deviation of receiving voltage sensitivity.

  • LED칩 (발광 피크: 405nm)과 4 종의 형광체 (Blue, Green, OrangeRed, Red)를 이용하여 D65 표준광원r과 유사한 발광 스펙트럼을 가지는 광원을 제작하였다. 실험계획법을 활용하여 형광체간에 교호작용과 농도 변화에 따른 스펙트럼의 형상 변화 경향을 파악할 수 있었으며, 이들 결과를 실험계획법에 의해 최적화함으로서 D65 표준광원과 유사한 스펙트럼을 가지는 광원을 제작할 수 있었다.
