ABSTRACT: Mixed-variable problems are inevitable in engineering.
However, few researches pay attention to discrete variables. This paper
proposed a mixed-variable experimental design method (ODCD): first, the
design variables were divided into discrete variables and continuous variables;
then, the DVD method was employed for handling discrete variables, the LHD
method was applied for continuous variables, and finally, a Columnwise-Pairwise
Algorithm was used for the overall optimization of the design matrix.
Experimental results demonstrated that the ODCD method outperforms in terms of
the sample space coverage performance.
