[0042] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in conjunction with the accompanying drawings in the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0043] As an important part of oil and gas import channels, the normal and stable operation of overseas oil and gas pipelines is related to energy security issues. Since multiple agencies such as local government, resident embassy and parent company of the investment party are involved in the process of accident emergency response, a unified mechanism needs to be established to ensure the orderly dissemination of information during the response process, reduce the information transmission and completion time of all response tasks between agencies, and improve the response and disposal efficiency. At present, the related research on task time sequence mainly focuses on the information dissemination relationship and the construction of event topological relationship based on graph theory. The sequence diagram (time sequence diagram) of the standard modeling language UML (Unified Modeling Language) qualitatively shows the dynamic cooperation between multiple objects by describing the time sequence of sending messages between objects. The multi-agent system regards the system as a linkage system composed of multiple intelligent agents, each of which has the ability to autonomously decide the next action. Global reasoning is often combined with reinforcement learning, but the ability to solve the problem of multi-head diffusion of information dissemination is weak. In addition, there are also event topological relationship construction based on graph theory, including AOV, AOE network and other common information dissemination models such as influence model and infection model. However, in the process of emergency response, the completion of each task in sequence has the phenomenon of time decay of disposal value, which cannot complete all emergency tasks in the shortest time, resulting in low disposal benefit.

[0044] To solve the above problems, the present application provides an overseas oil and gas pipeline accident emergency disposal linkage method, analyzes and identifies the agency units and task units along the overseas pipeline, defines the unit actions, time consumption parameters and disposal values of the agency units and task units, establishes an agency emergency linkage network model to describe the orderly linkage between the agency units and task units in different scenarios and response requirements, activates and propagates in the agency emergency linkage network model, calculates the cumulative sum of benefits, and selects the best propagation scheme according to the cumulative sum of benefits.

[0045] The technical solutions of the present application are described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described in detail in some examples.

[0046] Figure 1 The process of the overseas oil and gas pipeline accident emergency disposal linkage method provided by an embodiment of the present application Figure 1 The execution subject of the present embodiment can be a server or other computer devices.

[0047] As shown in Figure 1 The method of the present embodiment can include the following steps:

[0048] S101, obtaining each institution along the line corresponding to the overseas oil and gas pipeline accident and each task to be disposed.

[0049] In the present embodiment, the each institution along the line corresponding to the overseas oil and gas pipeline accident includes: oil and gas pipeline company institutions, local organization institutions and other organization institutions. The each task to be disposed along the line corresponding to the overseas oil and gas pipeline accident represents specific emergency disposal tasks performed by the on-site rescue and repair team and other groups, and the main goal is to take response actions as soon as possible according to the superior's order, reduce the impact of the accident consequences, restore the pipeline function, and return the disposal progress.

[0050] Specifically, the oil and gas pipeline company institution: the oil and gas pipeline company is a project unit of a cross-border pipeline. The oil transportation company is responsible for the operation and management of the entire pipeline and the management of the life logistics. The company headquarters will be set up in a large city with convenient communication and transportation conditions. General departments include production operation department, safety department, etc. Local organization institution: in the overall framework of large-scale accident response, the management department of the pipeline location is generally the first leader. The pipeline accident will be reported to the local management department as a production safety accident. The management department will mobilize the way area. The setting of the subordinate department depends on the pipeline way area. Other organization institutions: in the overseas pipeline emergency disposal, relevant emergency institutions may be added according to the company situation. In addition, it may also include the news media, local private forces, etc. Each task to be disposed includes specific emergency disposal tasks performed by the on-site rescue and repair team and other groups. The main goal is to take response actions as soon as possible according to the superior's order, reduce the impact of the accident consequences, restore the pipeline function, and return the disposal progress.

[0051] S102, representing each institution as an institution unit, and setting the unit action and time consumption parameter of each institution unit.

[0052] In this embodiment, the mechanism is the basic unit in linkage, responsible for accepting, processing and disseminating information about the accident, emergency needs and orders. The mechanisms communicate with each other, and can also make autonomous decisions according to environmental information. The functions of each mechanism are highly abstracted to obtain a standard emergency response mechanism unit.

[0053] The mechanism unit can perform one action at each time, including receiving information, processing information and sending information, which constitutes the action set A = {Receive, Process, Send}.

[0054] There are three sources of received information: receiving the disposal order issued by the superior, receiving the cooperation information issued by the peer, and receiving the accident report information from the subordinate. The time consumed by the mechanism unit j to accept the information action is denoted as t rec j .

[0055] Processing information is mainly to verify the information source, integrate the reported data, and prepare disposal tasks and material requirements. The time consumed by the mechanism unit j to process the information action is denoted as t prc j .

[0056] There are three types of objects for sending information: reporting accident information to the superior, issuing diffusion / collaboration requests to the peer, and issuing disposal instructions to the subordinate. The time consumed by the mechanism unit j to send the information action is denoted as t send j .

[0057] S103, each to-be-disposed task is represented as a task unit, and the unit action, time consumption parameter and disposal value of each task unit are set.

[0058] In this embodiment, the action of task unit i is simplified to include two types: receiving orders (preparing and executing) and reporting information (reporting disposal progress), corresponding to time consumption t rec i and t send i , respectively. The disposal value of task unit i is to quantify the progress of the current emergency disposal work, and to assign a value to the activation state of the task unit. The task disposal value of task unit i in the accident emergency response is denoted as v i .

[0059] S104, according to the linkage relationship between each mechanism unit and the linkage relationship between each task unit and the mechanism unit, an emergency linkage network model of the mechanism is established; wherein the initial state of each mechanism unit and each task unit is an inactive state, and after any mechanism unit executes the corresponding unit action according to the corresponding time consumption parameter and enters the active state, it will trigger the mechanism unit or task unit with the associated relationship to execute the corresponding unit action according to the corresponding time consumption parameter and enter the active state.

[0060] In this embodiment, the level of each organization unit is set, and the level of the organization unit j∈{1, 2, …, J} is denoted as l j In the modeling process, the levels 1, 2, 3, … can be assigned from bottom to top according to the organizational structure. The linkage relationship between each organization unit is established according to the level; the linkage relationship between each task unit and the corresponding organization unit is established according to the relationship between each organization unit and the task performed by each organization unit; and the organization emergency linkage network model is established according to the linkage relationship between each organization unit and the linkage relationship between each task unit and the corresponding organization unit.

[0061] S105, in the organization emergency linkage network model, taking a preset target organization unit as an activation starting time, performing activation propagation between the organization units and the task units in the organization emergency linkage network model according to a preset execution logic; recording the activation propagation path and order between each organization unit and each task unit when all the task units enter the activation state as a propagation scheme.

[0062] In this embodiment, the preset execution logic includes one or more of the following cases: (1) maximizing the overall emergency disposal benefit, the earlier the emergency disposal starts, the higher the cumulative benefit is; (2) the number of starting units is not limited, and multiple starting propagation units can appear simultaneously or sequentially; (3) when an activated unit is in an activated state, it can start to act and transfer information; (4) a unit can only act in a single thread, and cannot accept, process or send multiple information at the same time; (5) the execution of disposal tasks is distinguished, and the next task cannot be executed in advance before the state of the previous task is returned. Whether an organization unit is activated is determined according to the unit action of each organization unit of the organization unit; whether a task unit is activated is determined according to the unit action of each task unit; and when all the task units enter the activated state, the propagation scheme at the current time is recorded.

[0063] S106, according to the time consumption parameters of each organization unit and the time consumption parameters and disposal value of each task unit, the cumulative sum of the benefits in a preset time period from the activation starting time in each propagation scheme is calculated.

[0064] In this embodiment, the sum of the benefits of all emergency disposals in a preset time period from the activation starting time is defined as the cumulative sum of the benefits in the time period. The greater the cumulative sum of the benefits, the more disposal tasks are completed earlier in the same linkage scheme when completing the same disposal tasks in the same time, i.e. the greater the robustness.

[0065] S107, the propagation scheme corresponding to the maximum cumulative sum of the benefits in the cumulative sum of the benefits is determined as the target propagation scheme, and the overseas oil and gas pipeline accident is disposed according to the target propagation scheme.

[0066] In this embodiment, one of all propagation schemes is selected as a current propagation scheme to obtain a first cumulative sum of benefits in a preset time period from an activation start time of the current propagation scheme; a second propagation scheme is searched from all propagation schemes to obtain a second cumulative sum of benefits in a preset time period from an activation start time of the second propagation scheme, and it is judged whether the second cumulative sum of benefits is greater than the first cumulative sum of benefits; if yes, the second propagation scheme is replaced by the current propagation scheme; if no, the current propagation scheme is kept; the steps of searching a next propagation scheme from all propagation schemes to obtain a cumulative sum of benefits in a preset time period from an activation start time of the next propagation scheme, and judging the cumulative sum of benefits in a preset time period from an activation start time of the next propagation scheme and the cumulative sum of benefits in a preset time period from an activation start time of the current propagation scheme are repeated until all propagation schemes are searched; and the current propagation scheme obtained after the searching is completed is determined as a target propagation scheme.

[0067] Specifically, after the target propagation scheme is determined, the overseas oil and gas pipeline accident is disposed according to the propagation order in the target propagation scheme.

[0068] In summary, the overseas oil and gas pipeline accident emergency disposal linkage method provided in the application obtains the institution units and task units along the overseas pipeline, defines the unit actions, time consumption parameters and disposal values of the institution units and task units, establishes an institution emergency linkage network model to describe the orderly linkage between the institution units and task units in different scenarios and response requirements, activates propagation in the institution emergency linkage network model, calculates the emergency linkage disposal benefits, and obtains an emergency linkage scheme with greater robustness by comparing the cumulative sums of benefits of different propagation schemes, so as to ensure that all emergency disposal tasks are completed in the shortest possible time in the actual response process.

[0069] Figure 2 The process of the overseas oil and gas pipeline accident emergency disposal linkage method provided in an embodiment of the application Figure 2 In Figure 1 On the basis of the embodiment, Figure 2 The process of calculating the cumulative sum of benefits in a preset time period from an activation start time in each propagation scheme is given, as shown in FIG. 6, the method of the embodiment can include the following steps: Figure 2

[0070] S201, determine the activation time consumption of each institution unit according to the time consumption parameters of each institution unit.

[0071] In this embodiment, the hierarchical division of each institution unit is as follows: each institution unit has a hierarchical difference according to the responsibilities and powers of the personnel constituting the main body. Let the level of institution unit j∈{1,2,…,J} be l​j The hierarchy 1, 2, 3… can be assigned from bottom to top according to the organizational structure.

[0072] Activation time of the organizational unit j As follows:

[0073]

[0074] Wherein, lagent send The hierarchy of the organizational unit sending the information to j. When the organizational unit j receives the command from the higher hierarchy, it is by default directly executed, i.e. directly activated. When the hierarchy of the information source organization is lower than or the same as itself, it needs to be processed after receiving the information, i.e. activated after the processing action.

[0075] S202, determining the activation time of each task unit according to the time consumption parameter of each task unit.

[0076] In this embodiment, since the hierarchy of all organizational units is higher than 0, when the task unit receives the command from the higher hierarchy, it is by default directly executed, i.e. directly activated. Therefore, the activation time of the task unit i is equal to the receiving time consumption t rec i .

[0077] S203, determining the state of each task unit at any time within the preset time from the activation starting time as the non-activated state or the activated state according to the activation time of each organizational unit and the activation time of each task unit, and obtaining the state value of each task unit at any time within the preset time from the activation starting time.

[0078] In this embodiment, the state of each task unit at any time within the preset time from the activation starting time can be determined as the non-activated state or the activated state according to the activation time of each organizational unit and the activation time of each task unit. Each task unit has two states, the non-activated state (0) and the activated state (1). Denote the state of the task unit i at t time as s t i ∈{0,1}. The initial state of the task unit j at 0 time is the non-activated state, denoted as s0 i =0. When the information is received and understood at t’ time, it is considered to be activated in the system, at which time it is denoted as s t’ i =1.

[0079] S204, calculating the cumulative sum of the revenue within the preset time period from the activation starting time of each propagation scheme according to the disposal value, the state value and the disposal revenue discount coefficient.

[0080] In the embodiment, the emergency treatment benefits of all task units at each preset time within a preset time period from the start time of the self-activation are calculated according to the treatment value and the state value; and the cumulative sum of benefits within the preset time period from the start time of the self-activation of each propagation scheme is calculated according to the emergency treatment benefits at each preset time and a treatment benefit discount coefficient.

[0081] Specifically, the emergency treatment benefits of all task units at each preset time within a preset time period from the start time of the self-activation are calculated according to the treatment value and the state value, and the calculation formula is as follows:

[0082]

[0083] In the formula, R t is the emergency treatment benefit of all task units at the preset time t; s t i is the state value of the task unit i at the preset time t, s t i = 0 when the state of the task unit is the non-activation state, and s t i = 1 when the state of the task unit is the activation state; v i is the treatment value of the task unit i.

[0084] Specifically, the cumulative sum of benefits within the preset time period from the start time of the self-activation of each propagation scheme is calculated according to the emergency treatment benefits at each preset time and a treatment benefit discount coefficient, and the calculation formula is as follows:

[0085]

[0086] In the formula, G t T is the cumulative sum of benefits within a preset time period of T unit times from the preset time t; and γ ∈ [0, 1] is the treatment benefit discount coefficient.

[0087] In summary, the overseas oil and gas pipeline accident emergency treatment linkage method provided in the embodiment introduces the treatment benefit discount coefficient which increases with time and decays, calculates the cumulative sum of benefits within a preset time period of T unit times from the preset time t, and obtains more accurate cumulative benefits of different treatment schemes by accumulating the cumulative sum of benefits within a period of time with the correction of the benefit discount coefficient.
