On the Admissible Region of Non-homogeneous Class Ratio for Grey Resource Model.

Grey resource model is the core model in the grey ecological resource exploitation theory for describing and forecasting development stages of resource efficiency. In order to define the application range of grey resource model, this study deduces the ranges of secondary parameter packages based on the coverage operations of grey numbers, and then deduces that of the development coefficient. Finally the admissible region of non-homogeneous class ratio for grey resource model is obtained in the form of both mathematical formula and numerical simulation of China's wind power industry and science & technology industry.
