An optimization algorithm using orthogonal arrays in discrete design space for structures

Discrete robust optimization algorithm based on Taguchi method for structural crashworthiness design

“…Furthermore, we also performed the deterministic discrete optimization as suggested by Lee et al (2003) to obtain the optimal solution to the hybrid TWB structures. Similarly, the mean value, standard deviation or SNR of optimal design obtained from deterministic discrete optimization method can be obtained, listed Fig.…”

“…1. The corresponding steps are detailed described in the following sections (Lee, Yi, Park, & Park, 2003).…”

“…However, the conventional DoE methods cannot consider the constraints in design. To tackle this problem, a new response which is called the characteristic function R new is defined to transform a constraint problem to a non-constraint problem by including the constraint violations as follows (Lee et al, 2003):…”

“…In addition, Green et al [23] applied orthogonal arrays to conjoint analysis in marketing. Also, Lee et al [24] used an iterative optimization algorithm with orthogonal arrays in discrete space for structure design. The feasibility of a method that combines orthogonal experiment theory with the finite element method (FEM) was discussed by Wang et al [25], who used this method to compute and evaluate the three dimensional (3-D) natural stress field.…”

An Improvement of a Non-uniform Concentration Inequality for Randomized Orthogonal Array Sampling Designs

“…B., 1997) and (Tang, B., 1993). In this article, we use the orthogonal array sampling which provide many applications ( (Davis, J., 2007), (Lazic, L., 2008), (Lee, K. H., 2003) and (Lin, K. P., 2008)) and the definition is stated as follow.…”
