dc.description.abstract | Solutions to the deterministic design optimization cannot consider the uncertainties that may occur from the tolerance of design variables, noise and environmental factors, material properties, and uncontrollable operations. Therefore these solutions may cause the possibility of failure. However, reliability-based design optimization (RBDO) can provide the reliability of a system by mean of probabilistic design criteria, i.e., possibility of failure. To assure these criteria, many methods for the reliability analysis have been developed. However, these methods assume that data take one of continuous forms of distribution functions. In real problems, because real data may often provide discrete form, it is important to estimate the distributions from discrete data in the reliability analysis. In this paper, we introduce BIC method that can determine the best estimated distribution for discrete data. These distributions are used for reliability analysis in RBDO. Mathematical example is illustrated to verify the proposed method. In engineering example, bogie frame is illustrated to apply the proposed method.
