K-$BEtest^{(R)}$ is a well known program for bioequivalence test using a $2{ imes}2$ design. Lee et al.(1998) and Park et al.(1999) suggested a $3{ imes}3$ and $3{ imes}2$ design, and also discussed their benefits. We developed a computer program, called BioEquiv, which can analyze some complex experimental designs such as, $3{ imes}3$ design and $3{ imes}2$ design including a standard $2{ imes}2$ design. This program is a user-friendly one and overcomes the disadvantages of K-$BEtest^{(R)}$. The detailed statistical formula and structure of BioEquiv are presented with some examples. The comparison between K-$BEtest^{(R)}$ and BioEquiv are given with actual data analysis. BioEquiv is able to present a table of ANOVA test over some complex experimental designs. Moreover K-$BEtest^{(R)}$ and BioEquiv draw the same result when data consists of $2{ imes}2$ design.
