Embodiment Construction
[0039] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.
[0040] The calculation method of the fuzzy weight adopted by the present invention is as follows: it is assumed that the evidence X is connected with the hypothesis of "appearance" of a certain mine D. X = {xi, x2, . . . , xn}. In mineral resource evaluation, xi can be rock category, singular value category, etc. In the usual discrete statistical methods, X is used to construct binary and ternary variables. The steps are as follows: a binary pattern consists of two subsets, A and A (not A), and A∪ A=X; A∩ A=0, that is, A and A are mutually exclusive. A binary variable that falls into set A has a value of 1, and a binary variable that does not fall into set A or falls into set A has a value of 0. If a single binary pattern is not sufficient, more binary patterns can be generated from X. Unlike traditional weight-of-evidence methods, fu...
