Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The overseas oil gas pipeline is taken as an important component part of the oil gas inlet channel, and the normal and stable operation of the overseas oil gas pipeline is related to the energy safety problem. Because the accident emergency response process involves reporting local government, residence messenger, investors and other multi-party institutions, an overall planning mechanism needs to be established to ensure orderly transmission of information in the response process, reduce information transmission among institutions and completion time of all response tasks, and improve response disposal efficiency. At present, task time sequence relation related researches mainly focus on information propagation relations and event topological relation construction aspects based on graph theory. The standardized modeling language UML (Unified Modeling Language) sequence diagram (timing diagram) qualitatively displays dynamic collaboration between objects by describing the temporal order in which messages are sent between objects. The multi-intelligent system regards the system as a linkage system consisting of a plurality of intelligent agents, wherein each intelligent agent has the capability of autonomously determining the next action, and global reasoning is commonly performed in combination with reinforcement learning, but the capability of solving the information propagation problem with multi-head diffusion is weak. In addition, there are event topology relation construction based on graph theory, including AOV, AOE network, etc. and common information propagation models including influence model, infection model, etc. However, in the emergency response process, the treatment value is attenuated with time after each task is completed, so that the treatment of all emergency tasks cannot be completed in the shortest time, and the treatment benefit is low.
Aiming at the problems, the application provides a method for emergency handling linkage of accidents of overseas oil and gas pipelines, which is used for analyzing and identifying mechanism units and task units along the overseas pipelines, defining unit actions, time-consuming parameters and handling values of the mechanism units and the task units, establishing a mechanism emergency linkage network model to describe ordered linkage between the mechanism units and the task units under different scenes and responding to requirements, performing activation propagation in the mechanism emergency linkage network model, calculating a cumulative total of benefits, and selecting an optimal propagation scheme according to the cumulative total of benefits.

There are three types of sources of received information: receiving a disposal command issued by an upper stage, receiving cooperative information sent by a peer, and receiving accident report information from a lower stage. The time consumption of the recording mechanism unit j for receiving the information action is t rec j 。
The information is processed primarily to verify the source of the information, integrate the reporting material, and prepare for the task of disposal and the material requirements. The time consumption of the information processing action of the recording mechanism unit j is t prc j 。

In this embodiment, the hierarchy of each mechanism unit is set, and the hierarchy of mechanism unit J ε {1,2, …, J } is l j . In the modeling process, layers 1,2 and 3 … can be assigned from bottom to top according to the organization structure.

In this embodiment, the sum of the benefits of all emergency treatments within a preset period defined as the starting time of self-activation is referred to as the sum of the benefits accumulated during that period. The larger the sum of the revenue totals, the earlier the more treatment tasks are completed, i.e. the greater the robustness, representing different linkage schemes that complete the same treatment task in the same time.
And S107, determining a propagation scheme corresponding to the maximum profit accumulation sum in the profit accumulation sums as a target propagation scheme, and carrying out emergency treatment on the overseas oil and gas pipeline accidents according to the target propagation scheme.

wherein G is t T Is a cumulative total of earnings in a preset time period of T unit times from a preset time T; gamma e [0,1 ]]To handle the revenue discount coefficient.
