灰靶决策的灰效用理论研究

A Study of the Grey Utility Theory for Grey Target Decision

提出了灰效用函数的概念，给出了灰效用函数存在的公理体系．讨论了灰靶决策的灰效用理论。

The concept of the grey utility function is proposed and the axiomatics for the existence of grey utility function are given. Although the grey target decision is an important part of grey decision theory, yet no theoretical support for its study has so far been reported. The grey utility theory for grey target decision is discussed, which is expected to provide a basis to the grey decision with available grey information.
