| 摘 要： | 对灰靶理论的灰靶变换进行了理论基础分析。对于邓氏灰靶变换，证明了在序列取值于正数范围内时可以作为极大值极性和极小值极性指标列的灰靶变换；通过给出特殊例子说明了对于适中值极性指标序列，该变换不满足灰靶变换的定义。给出了一个适合于三种极性的灰靶变换，进一步完善了灰靶理论的计算问题。给出了新的灰靶变换在经济中的应用，调整了已有文献的一些结果。

| Abstract: | Study the theoretical analysis on gray target transformation.As to the Deng's transformation,it is proved to be suitable for POL(max) and POL(min) criterion sequence when taking positive value;An observation is constructed to show that it is not suitable for POL(mem) criterion sequence in terms of the definition of grey target transformation.A new gray target transformation,suitable for the sequences of the above three types,is proposed.And application in economics of the new transformation is demonstrated,adjusting some results in some preceding paper. |
