Example can effectively pick out the key node in composite communications transport network, in Network System Reliability promotion, security risk prevention and control
Work in, can shoot the arrow at the target emphasis safeguarded, reinforced before calamity, for promoted composite communications transport network cope with natural calamity
With emergency event ability, improves transportation system reliability and lay the foundation.
This embodiment of the present invention proposes a kind of appraisal procedure of composite communications transport network node different degree.Firstly, knot
The feature of conjunction composite communications transport network and different network abstraction method applicabilities, propose towards composite communications transport network
M ulti- Ethernet topology structure extraction method；Secondly, considering the network size of each transportation trade, the speed of service, Ke Huozhou
Turn the factors such as amount, proposes the weight calculation formula on each sub-network topology side；Third chooses weighting node degree and weighting node betweenness
For evaluation index, the appraisal procedure of composite communications transport network node different degree is proposed.Specific flow chart is as shown in Figure 2.
Specific embodiment is as follows:
(1) explanation and hypothesis of m ulti- Ethernet topology building
1) using city as node: when city possesses 1 or more railway station or airport, or having 1 or more public affairs
When road is passed through, then the city is abstracted as a node；
2) side in m ulti- Ethernet topology: in the sub-networks topology constructing such as highway, railway and civil aviaton, the number on side between node
It measures consistent with highway item number, railway item number and the course line quantity being actually connected.But in the composite web of the embodiment of the present invention
Line is not repeated when network topology constructing；Although that is, existing highway is reachable between city A to city B, and having railway or civil aviaton can
It reaches, but in m ulti- Ethernet topology, only has a line to be connected between node A and node B.
3) weighted network: due to the infrastructure scale of the transportation trades such as highway, railway, civil aviaton, water route, passenger and freight
Volume of the circular flow, travelling speed etc. otherness are larger；Therefore in this embodiment of the present invention, two sections when extracting m ulti- Ethernet topology
Functional attributes, reliability of mode of transportation difference representative edge being connected between point etc. is also different.Therefore when constructing composite network,
Weighted network is selected, to embody the difference on composite network side.
4) Undirected networks.Can be round-trip if being connected between usual city A and city B, the line of node A and node B
It is undirected；Therefore in the composite network constructed in embodiments of the present invention, it is assumed that be Undirected networks between any two node.
(2) building of composite network
Using city as node, composite network is constructed using L space-wise.It specifically includes: acquisition highway, railway, the people first
Boat, the network topology of water transport and corresponding adjacency matrix, wherein the highway, railway, civil aviaton, water transport adjacency matrix remember respectively
Make Mh、 Mr、Ma、Mw；Then it according to the m ulti- Ethernet topology of this four adjacency matrix building composite communications transport networks, and obtains
The adjacency matrix M of composite networkc；Wherein McIt is calculated using the following equation:
Wherein
In above formula, ∨ indicates fuzzy operator, maximizing operation symbol；Indicate the i-th row jth column of composite network connection matrix
Element,The matrix element for indicating the i-th row jth column of composite network connection matrix, is basis
Highway, railway, civil aviaton, water transport between m ulti- Ethernet topology interior joint i, j connect determining.From formula (1) it is found that node i,
As long as there is a kind of topological adjacency matrix element of mode of transportation between jIt is not 0, then composite web
There is side to be connected between network topology interior joint i, j.
According to the basic database of each transportation trade, the mileage adjacency matrix of each network is extracted, is denoted as D respectivelyh, Dr,
DaAnd Dw.The mileage adjacency matrix of composite network is denoted as Dc, then DcCalculation formula it is as follows:
Dc=f (Dh,Dr,Da,Dw)
Wherein,
In above formula, f () indicates that median calculates function,Indicate the i-th row jth column of composite network mileage adjacency matrix
Matrix element, be according between m ulti- Ethernet topology interior joint i, j highway, railway, civil aviaton, water transport mileageDetermining.
(3) weight calculation on composite network side
The weight on composite network side has with the mode of transportation and its number of path being connected between m ulti- Ethernet topology interior joint i, j
It closes；Path is more between two nodes, then its weight is higher.Herein by the weight definition on composite network side between node each subnet
The sum of the weight on network side.The factors such as network size, the speed of service, passenger-cargo volume of the circular flow by each mode of transportation of consideration give different friendships
Logical mode assigns different weights.Below on the basis of highway, other modes of transportation are converted into the multiple relative to highway, are led to
Consideration above-mentioned factor is crossed, the weighing computation method of other modes of transportation is provided, calculation formula is as follows:
In formula, ωmFor the weight of mode of transportation m, for same class mode of transportation, the visitor that can also be respectively undertaken according to it
Goods volume of the circular flow, construction scale calculate the weight of different brackets road；SmAnd ShRespectively indicate the average fortune of mode of transportation m and highway
Scanning frequency degree；NmAnd NhRespectively indicate passenger-cargo volume of the circular flow of mode of transportation m and highway；LmAnd LhRespectively indicate mode of transportation m and public affairs
The total scale on road, i.e. infrastructure total kilometrage or airline mileage；fmFor the correction factor of the weight of mode of transportation m, value range
Between 0-2.
Then the weight on composite network side is calculated by the following formula:
Wherein,Indicate composite network sideWeight,Indicate the side of sub-network mWeight.
Since part rail track is passenger-cargo separation, shipping clock synchronization effect property is low compared with passenger traffic under event condition, therefore,
In pitch point importance assessment towards composite communications transport network system security risk analysis, passenger rail is only chosen as analysis
Object.Further, in the calculating of weight, the passenger person-kilometres of each transportation trade are only chosen as calculation basis.
By the above method, according to " 2017 year traffic carrier statistical communique of development ", in conjunction with highway mileage and passenger traffic
Volume of the circular flow data, by formula (3), the weight that various transportation trade network edges are calculated is as follows:
ωHighway=1.0, ωCommon railway=1.03, ωHigh-speed railway=19.75, ωWater route=0.01, ωCivil aviaton=0.21.
The weight calculation example on the composite network side of one two node is as follows:
Assuming that there is two railways between node 1,2, a highway is connected, then according to the above results, is answered by formula (4)
Close network edge e12Weights omega12For
ω12=1.03+19.75+1.0=21.78.
(4) index of composite network pitch point importance assessment determines
In Complex Networks Theory, node degree and node betweenness reflect the local importance of node in a network and complete respectively
Office's importance.Therefore, it is based on the studies above, is commented using weighting node degree and weighting node betweenness as composite network pitch point importance
The index estimated.
