从函数关系上看，假设目标因素A_(n+1)下各决定因素的权重系数w_1

From the functional relationship point of view, assuming the weight coefficients w_1,w_2,…,w_n of the determinants under the target factor A_(n+1), there must be (∑_(i=1)^n▒w_i )=1,i =1,2,...,n. Therefore, the weight coefficient evaluation value P_w of the target factor A_(n+1) is:

From the perspective of functional relationship, assume the target factor a_ Weight coefficient w of each determinant under (n + 1)_ 1,w_ 2,…,w_ n. Then there must be (∑ (I = 1) ^ n ▒ w)_ i )=1,i=1,2,…,n。 Therefore, objective factor A_ Evaluation value p of weight coefficient of (n + 1)_ W is:

From the functional point of view, assuming the weight coefficients w _ 1, w _ 2, ..., w _ n of each decisive factor under the objective factor A_(n+1), there must be (∑_ (I = 1) NW _ I) = 1, I = 1,2, ..., n. Therefore, the weight coefficient evaluation value P_w of objective factor A_(n+1) is:
