Abstract
A special structure of the two level orthogonal array of order 12 is given. By using this structure and the method of constructing mixed-level orthogonal arrays presented by Zhang, Lu and Pang (1999), a lot of mixed-level orthogonal arrays of run size 108 are obtained. Especially, we obtain an orthogonal array of size 108 with 11 6-level columns.
