Abstract

To solve the problem of multI-causes process qualIty dIagnosIs In manufacturIng, an algorIthm based on the bInary tree of qualIty cause set and IntermedIate qualIty IndIces Is proposed. FIrstly, the set of qualIty cause Is dIvIded progressIvely to form a complete bInary tree, and then every node of the subsets Is chose as non-control cause set to construct the cause-selectIng control chart of the IntermedIate qualIty Index In Its parent node. In qualIty dIagnosIs, control charts wIth same parent are compared to narrow the scope of the abnormal qualIty causes untIl they are confIrmed eventually. PractIce proves that the new algorIthm proposed In thIs paper could make the procedure of qualIty cause judgment Independent to the adjustment one, and the comparIson tImes of control charts could be greatly reduced, so the effIcIency of dIagnosIs Is hIghly promoted.
