The effectiveness of grey relation entropy method and its rehabilitation

This paper shows a grey relation entropy method and analyzes the effectiveness of this method and the entropy relation grade. It proves that the grey relation entropy method has properties of the nonnegative, symmetry, extension extremism, and some other fine natures. The entropy relation grade still meets the four axioms of gray relation. We could use some natures for application´s process to make a more satisfactory progress provide the basis in practice. Finally, the grey relation entropy method is used to study the target value for Shuangyashan ecology industry garden and the synthetic evaluation target standard for national industry garden quality. The result obtained is the same with the basis biggest degree of membership principle which indicates the validity and feasibility with the entropy interrelatedness.
