A new multi-attribute intelligent grey target decision model is proposed. Four kinds of uniform effect measures of the effect measure for benefit type objective, the effect measure for cost type objective, the lower effect measure for moderate type, and the upper effect measure for moderate type are formed in view of different decision objective of benefit type, cost type, and moderate type which with a pleased field. Accordingly, the decision objectives which with different meaning, different dimension, and/or different nature can be transferred to uniform effect measure. So, the matrix of synthetic effect measures can be obtained easily. The critical value of grey target is designed as the dividing point of positive and negative which is the zero point. The two cases of hit the bull’s eye or not of the objective effect value are fully considered. The distinguishing rate between synthetic effect measures is improved greatly.
