SiA specific disaster model group service chain. And checking the correctness of the specific disaster model group service chain according to the abstract disaster model group service chain structure. Specifically, the service chain structure is represented by an adjacency matrix, and it can be checked whether or not the adjacency matrices of the abstract disaster model group service chain and the concrete disaster model group service chain are consistent.
S106: and acquiring the priority order of the specific disaster model group service chain in the specific disaster model group service chain according to the QoS general index, and dynamically adjusting the specific disaster model group service chain according to the calling state.

The reasons for the link disconnection may include: in the first case, it is determined that some disaster model services cannot be activated according to user input characteristics (such as geographic elements) to cause link disconnection; or, in the second case, service chain outages due to the failure of certain disaster model services.
For the first case, when the activation parameter of a specific disaster model service is determined to be 0 after the user inputs the model operation parameter, it indicates that the area parameter cannot trigger the disaster of the next node, and therefore, it is necessary to automatically delete the non-activated node and its related subsequent nodes in the abstract disaster model group service chain and regenerate the abstract disaster model group service chain and the corresponding specific disaster model group service chain.
And aiming at the second situation, automatically comparing the QoS of each specific service chain of the two schemes which are executed from the initial node and executed from the failed node, selecting the specific disaster model group service chain with the highest QoS value from each scheme for comparison, and finally selecting the specific model group service chain with the higher QoS as a replacement scheme.
S107: and releasing the specific disaster model group service chain.
In this embodiment, the issuing the specific disaster model group service chain may include: describing the specific disaster model group service chain based on the expanded WSDL (for example, adding a label < behavior > describing service behaviors in a service description document, specifying a transmission object and a transmission state of a service node in the < behavior > label, and setting a conversion function to complete transmission between the node and the node); packaging the specific disaster model group service chain into a standard WPS service by using a programming language; and deploying the specific disaster model group service chain on a server, and registering and releasing the specific disaster model group service chain in a service registration center.
Taking a specific embodiment as an example, the received request information input by the user is: x month and X day in X year, earthquake occurs in Shenzhen (longitude: XXX latitude: XXX) region, landslide phenomenon occurs in nearby mountain, disaster crisis occurs, and disaster prediction information such as earthquake influence range and the like needs to be obtained within 15 minutes. Firstly, semantic extraction operation is carried out on disaster types and disaster model QoS index requirements, information which is closely related to disasters is intelligently analyzed and reported by using a natural language processing method, intelligent reasoning assistance is carried out by using a knowledge graph, related disaster basic elements and QoS index constraints are deduced, intelligent conversion from unstructured language information to structured input information is completed, and finally, two disaster keywords of 'earthquake' and 'landslide' are extracted, and two model index constraints of corresponding time T <900s and earthquake influence range prediction in QoS indexes are extracted.
And inquiring a disaster chain rule database, judging whether the earthquake and landslide nodes are in the same disaster chain, wherein the inquiry result shows that the earthquake and the landslide nodes are in the same disaster chain, and the earthquake and landslide nodes are not cyclic nodes at the same time, so that the earthquake of the front-sequence node is taken as an initial node of a service chain.
And (3) extracting an earthquake disaster chain from the disaster chain rule by taking the earthquake node as a query key word, discovering all candidate earthquake, landslide, debris flow and ground settlement disaster model services from a service registry of the model group management system, respectively establishing all candidate services in an earthquake model service group, a landslide model service group, a debris flow model service group and a ground settlement model service group according to the disaster type of each node, and performing QoS index sequencing to remove inferior services.
The 'earthquake' model abstract service chain is provided with four nodes of 'earthquake', 'landslide', 'debris flow' and 'ground settlement', three candidate 'earthquake' model services are arranged in an earthquake model service group, two candidate 'landslide' model services are arranged in a 'landslide' model service group, two candidate 'debris flow' model services are arranged in a 'debris flow' model service group, one candidate 'ground settlement' model service is arranged in a 'ground settlement' model service group, one disaster model service is selected from the four disaster model service groups each time to form a specific disaster model group service chain, and 3 x 2 x 1 x 12 can be obtained in total.
And detecting whether the structure of each specific disaster model group service chain is consistent with that of the abstract disaster model group service chain. Specifically, the adjacency matrix is used for representing the service chain structure, and whether the adjacency matrixes of the abstract service chain and the concrete service chain are consistent or not is detected.
Figure GDA0002507759170000111
A is an adjacent matrix of the seismic model abstract service chain, and whether the adjacent matrix of the concrete seismic model service chain is also A is checked.
Fig. 3 is a schematic diagram of an equivalent service chain form according to an embodiment of the present invention. Analyzing the structure of the seismic model service chain can obtain an equivalent service chain form as shown in fig. 3:
analyzing the equivalent service chain, the earthquake and landslide model service respectively runs once, the debris flow model service runs twice, and the ground settlement model runs three times, so that the calculation formula of each index element in the earthquake service chain can be obtained by calculation and simplification according to the formula:
R＝R1{1-{1-R2[1-(1-R3R4)(1-R4)]}(1-R3R4)}
A＝A1{1-{1-A2[1-(1-A3A4)(1-A4)]}(1-A3A4)}
T＝T1+T2+T3+T4
TP＝MIN(A,B,C,D)
Figure GDA0002507759170000121
C＝C1+C2+2C3+3C4
using an analytic hierarchy process, referring to expert opinions in the field, and then giving the weight values of all indexes, the final calculation formula is as follows:
Q＝w1R+w2A+w3T+w4TP+w5RP+w6C
and selecting a concrete disaster model group service chain with the highest QoS value to be preferentially bound with the abstract disaster model group service chain to execute calling.
Due to the disaster characteristics of the disaster model service, the following situations are designed during the execution and the specific disaster model group service chain needs to be dynamically adjusted:
1. judging that a link is disconnected due to the fact that part of disaster model services cannot be activated according to user input features (geographic elements and the like);
2. service chain outages due to service failures in some disaster models.
The module can dynamically adjust the specific disaster model group service chain according to different link disconnection reasons.
For the first case, when the activation parameter of a specific disaster model service is determined to be 0 after the user inputs the model operation parameter, it indicates that the area parameter cannot trigger the disaster of the next node, so that the inactive node and its related subsequent nodes are automatically deleted from the abstract disaster model group service chain, and the abstract disaster model group service chain and the corresponding specific disaster model group service chain are regenerated.
Aiming at the second situation, the invention comprehensively compares the QoS index values of each chain under the conditions that the analysis is executed from the initial node of the service chain and the analysis is executed from the failure node according to the QoS index, and selects the optimal scheme to dynamically adjust the service chain of the specific disaster model group.
The transmission object is determined according to the structure of the service chain, and a conversion function is set to convert the output of one node into the input of the next node. For example: adding < behavior > tags in the WSDL document, wherein the lower secondary tags are < objectservice >, < state > tags, the < objectservice > tags are provided with < objecturl >, and other services transfer the access addresses of the target objects, the < state > tags are used for defining the transmission state of the services, and the next service is activated through the change of the service state. And packaging the WSDL document into a standard WPS service by using a script language according to the content of the WSDL document in the service chain. And deploying the new service chain on the server and registering and publishing the new service chain in the service registry.
