Fuzzy techniques are playing an increasing role in current intelligent computations and opt-imizations.How to reasonably describe and measure uncertain information hasbecome urgent in many pract-i cal domains such as artificial intelligence, computer techniques,control and optimizations in complex manu-facturing systems.In view of the shortcomings of poor systematicness and indistinct structure features of current measuring ways for fuzziness, The intrinsic implications and performance of the axioms for fuzziness are analyzed and the concept of fuzziness feature function are proposed to describe the fuzziness.T his will help us to find fuzziness measures with general meaning.
