勘查基地选择的灰色模糊决策方法

根据区域地质、成矿等特征，构置待选勘查基地特征地质变量，并按其性质、可比性等进行划分与归并，建立变量递阶层次模型．利用l--9比较标度法进行变量的初步量化、变换与多重赋权处理．根据成矿、找矿理论设计功效函数进行指标化，利用综合可能度模型、多维加权贴近度模型和灰关联度模型分别确立勘查基地选择的优先序，为勘查基地选择决策提供依据．

Decision Method of the Gray Blur for Selection of Prospective Base

The geologic variable of the character of prospective base to be selected is set up according to the character of the regional geology and metallogeny etc. On the basis of some characters,and comparability etc, the division and mergence are carried out in order to successively establish variable stratified models. The initial quantization,variation and multi-weighted process used from No .1 to 9 comparable scale method are variable.The normalization are carried out by the designed effect function according to the theory of metallogeny and looking for mineral deposits. The preferential order of prospective base to be selected are respectively determined by the multiple possibility model, multi-dimension weighted close degree method and gray related model in order to provide the basis of selecting decision of prospective base.
