In this paper, interaction patterns in L_<18> orthogonal array are classified as the confounding patterns between interaction and main effect ,and the degree of confounding is evaluated quantitatively for each pattern. An equivalence relationship is defined among the forms of confounding patterns to classify into several confounding patterns. To evaluate the degree of confounding quantitatively, the ratio of sums of squares between interaction and main effect are used. For instance, these results suggest that when there are only factors with three levels and the number of factors is six at most, these factors should be assigned from the third column to reduce the confoundings as least as possible.
