The grey system theory is new methodology useful for the study of unascertained situations whose information is missing and extenics is a another one to solve the contradictory problems. Under the information-missing situation, the values of some characteristics are grey. We propose the grey basic-element to treat this situation. The decision-makers can utilize it to solve the contradictory problems under uncertain situation.
