Polygamy is strong, the features such as having a great responsibility, generally by urban planning, topography and geomorphology, engineering geology and hydrogeologic condition, ground and ground
The multifactor impact such as lower building and traffic above-ground situation.Traditional scheme comparison and design method based on two dimensional surface are usual
It is difficult to integrate the important informations such as city three-dimensional building thing, geology, road, pipe network, causes scheme comparison to be made a fault, designs appearance
The situation of deviation occurs again and again.Such as there are new construction underground pipe network existing with city, building means of transportation etc. and rush
It is prominent, and then design alteration occurs, it may cause largely to remove, transform and change shifting work, to engineering construction and the ring of area along the line
Border produces significant impact.
Fast-developing recently as urban track traffic, scheme comparison and design are also progressively real from two dimensional surface to three-dimensional
Body changes.Particularly GIS-Geographic Information System (GIS) technology provides good technology branch for track traffic design and scheme comparison
Support.Generalized information system is based on spatial database, has good advantage in terms of displaying large scene, but details show but exist it is larger
Deficiency, it is difficult to provide stronger guidance to comparison and selection of routes.
Currently used scheme comparison work, Decision-making of Design Scheme person need to consider the influence of many factors, defined
The weight of different affecting factors assesses each alternative, and look for by the trap queuing of each alternative to establish decision model
Go out preferred plan.Currently used Tactic selection method, such as analytic hierarchy process (AHP) (AHP), fuzzy AHP (fuzzy AHP), Delphi
Method (Delphi), Network Analysis Method (ANP) etc., all it is that tax power is carried out for the attention degree of each attribute according to expert, comes under
Subjective weight setting method.The flexible strategy of subjective weights inevitably vary with each individual, and the overall merit knot obtained by different weights
Fruit is probably different.

The idiographic flow of step 6 is as shown in figure 3, specific implementation method is as follows：
(6.1) decision matrix is established；
Multiple attribute decision making (MADM) matrix is defined by " attribute " with " scheme ", and decision model of the invention uses uncertain information,
Therefore the assessed value in decision matrix is presented in a manner of grey number, i.e.,The presentation such as formula (1) of whole decision matrix：
From formula 1, matrix that decision matrix is made up of n scheme and m attribute, wherein,Represent
Grey number assessed value of i-th of scheme on j-th of attribute.
(6.2) uncertain information is defined；
This example uses six large attribute indexs：Operational effect and economic benefit, construction costs, Line technology route, it can implement
Property, the accordance of attracting passenger flow effect and upper planning.
The impact evaluation value of above-mentioned six large attributes index be often difficult to it is specific given, but still can rely on the information obtained and
Cognition, a section is given to assessed value, this section is grey number.The present invention defines uncertain letter using the concept of grey number
Breath, using non-definite value, but the form of numerical intervals is scored, and relatively meets the objectivity of human nature perception.
(6.3) data pre-processing；
In terms of data pre-processing, using the broad sense gray relative pretreatment technology model of grey number, as shown in Figure 4.According to Fig. 4
Carry out data pre-processing discussion so that the grey number assessed value of generation is
(1) whenWhen,
Due toPositioned at the left of generating function, the problem of not obscuring sequentially, the formula under this situation is：
Wherein,For the grey number assessed value after generation.
(2) whenWhen,
Due toCoverLeft, it is therefore necessary to consider that desired value is 1 it is assumed that formula under this situation
For：
(3) whenWhen,
Now,Cover wholeConsider desired value be generated as 1 it is assumed that the generation formula under this situation is：
(4) whenWhen,
Now,CoverRight, in addition to desired value is contemplated and is generated as 1 hypothesis, need consider order
The problem of obscuring, the generation formula under this situation are：
(5) whenWhen,
Now,Positioned at the right of generating function, the problem of order is obscured be present, therefore can be by the generation under this situation
Formula remittance is whole to be：
(6.4) weight setting；
Information that objective weight basis of design decision matrix is provided determines weight, mainly weighs in attribute between data
Deviation degree, when the deviation in attribute is bigger, represents that the attribute more has taste, higher weight can be given.Accordingly
Concept, the present invention first derive the perfect number weight setting model based on deviation maximization.
Certain decision matrix is X=[xi(j)]n×m, normalized matrix R can be obtained after normalization, it is assumed that weight vectors are：
W=[w (1), w (2) ..., w (m)], w (j) >=0,
For attribute u (j), scheme r in attributeiDeviation between other schemes may be defined as：
Wherein, riFor xiFormation sequence.Then, make：
Δ (j) is represented in attribute u (j) Inner, the total deviation of weighting of all schemes.According to the concept of deviation maximization, weighting
Vectorial w distribution should make the total deviation of weighting of all properties be maximum.Therefore, its object function can be set to：
Then, the w of following optimization model is solved, you can obtain the weight vectors of deviation maximization：
If solving this optimization problem with Lagrange functions,：
Its gradient is sought, and is made：
Optimum solution, which can be obtained, is：
Further, since typically using unitization weight in decision model, therefore w (j) is subjected to unitization processing again,
I.e.：
It can thus be concluded that：
Formula 16 to handle the weight setting mode of perfect number, to expand to grey number space when, then must further
Define δi(k) calculation., can be by δ according to grey number Ming Kaosiji distance functionsi(k) it is defined as：
Now, in this grey number distance generation, is returned into formula 16, you can obtain objective weight setting value.
(6.5) association analysis；
After obtaining attribute weight, the association analysis between grey numeral sequence is calculated.Reference sequences and grey number are analyzed in association analysis
Relevance between decision matrix, it is by based on distance function that its proximity degree, which judges,.
If reference sequences are defined as：
Bright Cowes cardinal distance is weighted from the basis as association analysis using the grey number between reference sequences and decision matrix, i.e.,：
Wherein,Referring to willWithThe sequence after pre-treatment is carried out for reference sequences, w (j) is grey number weight setting
The weight of j-th of attribute obtained by technology, p is Ming Kaosiji distance parameters, is most common euclidean distance as p=2.
On this basis, association analysis passes through the calculation formula of gray relation grades, you can is arranged according to size scheme preferential time
Sequence.
Wherein, dmin and dmax is respectively doiIn minimum value and maximum.
By decision matrix, pretreatment technology, weight and related analysis technology, urban rail transit line station can be carried out
Alternative priority ordering.ATTRIBUTE INDEX, definition and data source are shown in Table 1.
Table 1
(6.6) prioritization.
In step 6, by scoring six big indexs, distinguishing for each index directly can by the score calculation in decision matrix
Power Du not be assigned, on the one hand simplifies the flow of alternative competition, while reduces influence of the subjective weight to result.Scoring
It can be a section rather than definite value, relatively meet the objectivity of human nature perception.
