Results for Two-Level Designs with General Minimum Lower-Order Confounding

الملخص EN

The general minimum lower-order confounding (GMC) criterion for two-level design not only reveals the confounding information of factor effects but also provides a good way to select the optimal design, which was proposed by Zhang et al.

(2008).

The criterion is based on the aliased effect-number pattern (AENP).

Therefore, it is very important to study properties of AENP for two-level GMC design.

According to the ordering of elements in the AENP, the confounding information between lower-order factor effects is more important than that of higher-order effects.

For two-level GMC design, this paper mainly shows the interior principles to calculate the leading elements C1#2 and C2#2 in the AENP.

Further, their mathematical formulations are obtained for every GMC 2n-m design with N=2n-m according to two cases: (i) 5N/16+1≤n
