The second evaluation index weight calculation method is, compose the grade of the qualitative index in each technical scheme evaluation index parameter by setting with respective value, quantitative target gets its actual measured value; According to entropy and the weights of each evaluation index of each technical scheme evaluation index parameter value calculation; Wherein, entropy E _j=-k ∑ P _ijlnP _ij, (∑ P _ijbe each scheme value summation of jth item index, k is constant).P _ijfor the proportion of evaluation index, P _ij=X _ij/ ∑ X _ij; Xij is the desired value of lower i-th scheme of jth item index, ∑ X _ijthat the value of each scheme under a jth index is added.Weights W _j=d _j/ ∑ d _j; Dj is entropy E _jcoefficient of variation value (d _j=1-E _j).Such as, for qualitative index, be then divided into best with 1.0,0 is the poorest marking, and relatively good is 0.75, and poor is 0.5.Certainly, the present invention is not limited thereto, and also can be divided into other multiple rank, and determine that other are worth accordingly for each rank, as 11 ranks can be divided into, be followed successively by: 0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.0.Wherein, 1.0 are divided into best, and 0 is the poorest, and value means that more greatly index is better.

The computing method of the third evaluation index weights are, by being directly indices marking, obtain the weights of index, the rule of weights is weights sums at the same level is 1, and the weights of input must be less than or equal to effective value.According to the score value calculating mean value of given indices.

Step 103, according to each evaluation index parameter, calculates the evaluation index degree of membership of each environmental pollution prevention and control technology;

If Pi is index series, Pj is pattern sequence, composition matrix P.Then give a mark according to index situation.Concrete, economical index generates quantized value, and poly-talented index is divided into full marks with 10, and 0 is divided into extremely low point, then generates corresponding scores according to the performance of different index.Classification afterwards belonging to selective goal, determines degree of membership computing function, as: economical index, poly-talented index (little value is preferential), poly-talented index (large value is preferential).Calculate the degree of membership of environmental pollution prevention and control scheme numerical value afterwards.

Economical index, computing formula is as follows:

x _manrefer to the maximal value of each scheme of target, x _minrefer to the minimum value in target each side case value.X is currency.Poly-talented index, computing formula is as follows:

$\mathrm{\&mu;}\left(x\right)=\left\{\begin{array}{cc}0& x\&le;4\\ \frac{{(x-4)}^3}{8}& 4<x\&le;6\\ 1-\frac{{(x-8)}^2}{8}& 6<x\&le;8\\ 1& x>8\end{array}\right.$

Calculated by membership function and obtain subordinated-degree matrix L.

Step 104, the degree of membership that the weights calculated according to step 102 and step 103 calculate, calculates the comprehensive evaluation value of each environmental pollution prevention and control technical scheme.The weights of each evaluation index can select weights that in step 102, a kind of computing method obtain or the wherein average weight of evaluation index that calculates of two or three method.First ask the weights of index relative target, account form is the weights being multiplied by its rule layer with the weights of index, once up calculates, until destination layer.Successively to the weight computing of each index, obtain the weights of each index.According to the weight calculation method kind selected, obtain the weight matrix P of index.The P of step 104 calculating is multiplied by, judge value R=L × P with the L that step 103 calculates.Finally be normalized R, account form is G=Ri/ ∑ Rij (using the summation of each value divided by the value of R of R), obtains final evaluation result G.

The present invention, in order to improve convenience and the accuracy of analytical plan, can realize the comprehensive assessment of multiple environmental pollution prevention and control technical scheme flexibly.
