Index is set to characteristic parameter, is Xij(XijFor the jth index of boats and ships i, j=1,2,3 ... 10);
Step 3: determine optimal sequence according to Criterion Attribute: in judge index, boats and ships are insured situation, boats and ships acknowledgement of consignment scale, boats and ships
Carrier's transaction count, boats and ships carrier conclude the business tonnage, boats and ships carrier's dealing money, boats and ships carrier freight on time, boats and ships
Carrier's seven indexs of unloading on time are forward indexs, are the bigger the better, then the optimal sequence X of its correspondenceojFor:
X'oj=max (X 'ij), XojFor XijCorresponding optimal sequence, X'ijFor XijIn forward index;
Life of Ship in judge index, boats and ships carrier complained number of times, three indexs of boats and ships carrier's loading cost and leakage loss are
Reverse index, the smaller the better, then the optimal sequence X of its correspondenceojFor:
X”oj=min (Xi'j'), X "ijFor XijIn reverse index;
Step 4: data normalization processes: according to the attribute of each characteristic parameter, unites as the following formula participating in the initial data of analysis
One estimates process, and makees normalized simultaneously, each analytical data is compressed to [0,1] interval;
It is the index of forward to Criterion Attribute:
X'ij=Xij/maxX′ij
It is reverse index to Criterion Attribute:
X”ij=minX "ij/Xij;
Step 5: set up standardized analysis system after above-mentioned normalized, then sets up Lycoperdon polymorphum Vitt similar matrix, right
Coefficient of association, the degree of association, incidence matrix and Lycoperdon polymorphum Vitt similar matrix calculate: calculate XiTo XpCoefficient of association ζ at K pointi
(k):
XpK () is reference sequences, Xi(k)
For comparative sequences.
Calculate XiTo XpDegree of association γi:
Wherein n is boats and ships carrier's quantity of assessment;
Set up incidence matrix Γ:
γijIt is to assess with jth with the index series of i-th evaluation object for reference sequences
The index series of object is the degree of association of comparative sequences, and m is evaluation object number and optimal sequence sum, i.e. m=n+1;
Set up Lycoperdon polymorphum Vitt similar matrix G;
Wherein gij=(γij+γji)/2, γijAnd γjiFor the symmetry in incidence matrix Γ
?;
Step 6: inteerelated order arranges: in step 5, G matrix last column is i.e. with optimal sequence (Xoj) it is that reference sequences is tried to achieve
Inteerelated order, by gm1, gm2……gmm(gmm=1) sorting by size, the qualification quality that the order of its correspondence is assessment boats and ships is suitable
Sequence;
Step 7: arranged the qualification obtaining assessing boats and ships by the inteerelated order in step 6 and sort, take from Lycoperdon polymorphum Vitt similar matrix G
Go out the value of correspondence, the similarity formation sequence Z between the most adjacent sequence boats and ships:
Z=(Z1,Z2…Zn-1), ZiIt is the similarity between i-th and i+1 boats and ships.
Step 8: cluster analysis: set platform to ship classification boundary as λ (λ ∈ [0,1]), by the similarity sequence in step 7
Row Z with λ compares, and with λ for boundary, the acknowledgement of consignment qualification of assessment boats and ships is carried out good and bad level and divides.
A kind of boats and ships carrier's qualification evaluation methodology based on big data analysis the most according to claim 1, its feature exists
In, in described step one, hierarchical structure model includes:
Destination layer: be used for setting decision objective and carry quality assessment as boats and ships carrier;
Rule layer: the quality assessment of boats and ships basic condition, the quality assessment of boats and ships carrier's trading situation and boats and ships carrier clothes
The quality assessment of business quality;
Solution layer: choose Life of Ship, situation insured by boats and ships, boats and ships acknowledgement of consignment scale, boats and ships carrier's transaction count, boats and ships
Carrier conclude the business tonnage, boats and ships carrier's dealing money, boats and ships carrier meet with complaining number of times, boats and ships carrier to freight on time, ship
Oceangoing ship carrier unloads on time, ten evaluation indexes of boats and ships carrier's loading cost and leakage loss are as solution layer;
Boats and ships carrier in described destination layer carries quality assessment by the quality assessment of boats and ships basic condition in rule layer, ship
The quality assessment of oceangoing ship carrier's trading situation and the quality assessment of boats and ships carrier's service quality are constituted;
Boats and ships basic condition quality assessment in described rule layer by the Life of Ship in solution layer, boats and ships insure situation and
Boats and ships acknowledgement of consignment scale is constituted;
The quality assessment of the boats and ships carrier's trading situation in described rule layer by the boats and ships carrier's transaction count in solution layer,
Boats and ships carrier conclude the business tonnage, boats and ships carrier's dealing money and boats and ships carrier meet with complain number of times constitute;
The quality assessment of the boats and ships carrier's service quality in described rule layer freighted on time by the boats and ships carrier in solution layer,
Boats and ships carrier unloads on time, boats and ships carrier's loading cost and leakage loss is constituted.
