Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a method, device, equipment and medium for evaluating combat effectiveness based on a space information system. Background Art

[0002] Space information systems can use remote sensing, navigation positioning and communication and other technical means to conduct reconnaissance, detection, support and other combat activities in the combat area. Space information systems in the context of integrated joint operations can use the advantages of space technology to obtain, process and transmit information, so the performance of their equipment plays a key role in the success of combat missions. It can be seen that space information systems have an irreplaceable role in different tasks. It is necessary and urgent to evaluate their combat effectiveness.

[0003] The traditional evaluation of the combat effectiveness of weapons and equipment systems refers to the degree to which the weapons and equipment systems can achieve the expected goals under specific conditions and in specific combat missions. Combat effectiveness is not only related to the quality characteristics and quantity of the equipment set, but also to combat deployment and actual use in combat. Under different targets and battlefield environments, the combat effectiveness of weapons and equipment systems varies greatly.

[0004] The combat effectiveness evaluation of space information system must consider two characteristics. On the one hand, the space information system itself is an open and complex system. Its openness is reflected in the confrontation between the system and the combat parties during the combat process, and the influence between various capability factors is mutual and complex. Therefore, when evaluating its combat effectiveness, it is not enough to simply linearly aggregate the indicators, but it is necessary to fully consider its confrontational factors. The relationship must be highly nonlinear and uncertain. On the other hand, the space information system is not used in combat scenarios to carry out a single combat mission. Therefore, how to quickly and accurately evaluate its combat effectiveness for specific combat missions is an urgent problem to be solved. Summary of the invention

[0034] The present invention is described in detail below in conjunction with specific implementation methods and the accompanying drawings.

[0035] Method Embodiment

[0036] According to an embodiment of the present invention, a method for evaluating the combat effectiveness of a space information system is provided. Figure 1 and Figure 2 As shown, it is a flow chart of the method for evaluating the combat effectiveness based on the space information system provided in this embodiment. The method for evaluating the combat effectiveness based on the space information system according to the embodiment of the present invention comprises the following steps:

[0037] Step S1: Construct an initial combat effectiveness evaluation index system based on the space information system capability requirements for combat missions.

[0038] In this embodiment, the determination of the space information system capability is specifically carried out by analyzing the main mission, combat tasks and target requirements of the space information system, analyzing the composition structure, combat style and combat process of the space information system of the weapon equipment system from the perspective of information support, analyzing and proposing the capability requirements of the space information system for combat tasks, and then constructing a combat effectiveness evaluation index system of the space information system based on the analysis of the space information system capability.

[0039] An initial indicator system set is constructed based on the results of capability requirement analysis. The construction of the indicator system set is the premise and basis for constructing the domain mapping matrix. Therefore, the initial indicator system of the space information system is first constructed for the combat missions carried out by the space information system.

[0040] Step S2: Through the indicator system construction method, the task domain and the indicator domain are analyzed and represented in a correlation manner, the mapping relationship between the task and the indicator is determined, and a combat effectiveness indicator system set corresponding to the initial combat effectiveness evaluation indicator system is constructed.

[0041] In this embodiment, a method based on indicator system construction is proposed, which can reveal the mapping relationship between tasks and indicators. For example, the correlation analysis between task domain and indicator domain can be expressed through models such as CMM, DMM (domain mapping matrix), DCMM, DCAM, MD3M, etc. The mapping relationship between tasks and indicators is formed, and by exploring the relationship between them, indicators can be extracted from different tasks for rapid evaluation. In this embodiment, the DMM model is preferably used to construct a combat effectiveness indicator system set. Specifically,

[0042] refer to Figure 3 , which is the overall framework diagram of the DMM-based indicator system construction method provided in this embodiment. The domain mapping matrix is ​​a method for representing the information interaction relationship between two domains. The matrix is ​​composed of m row domain elements and n column domain elements, which are recorded as:

[0043] DMM i→j =(m ij ), i=1,2,…,m; j=1,2,…,n;

[0044] Among them, the matrix element m ij The value of m is 0 or 1. ij =1, it means that column domain element j outputs information to row domain element i, or column domain element j exerts influence on row domain element i; if m ij =0, it means that there is no information transmission relationship between the corresponding row and column domain elements, or there is no direct connection between the two.

[0045] This embodiment is based on the index system of the space information system constructed by the capability requirement analysis of the task-oriented space information system. In view of the problem that there are many types of combat tasks of the space information system, the traditional index system construction method is to establish an index system for specific combat tasks through construction principles, expert consultation methods and other methods. In order to achieve rapid evaluation of different tasks during the evaluation process, this embodiment uses the DMM model to perform correlation analysis on the task domain and the index domain, forms a mapping relationship between the task and the index, and by exploring the relationship between them, it is possible to extract indicators from different tasks for rapid evaluation.

[0046] Step S3: Determine the index system of the space information system for a specific task according to the operational effectiveness index system set, and simulate the index system of the space information system through the simulation system to obtain various index data.

[0047] Among them, simulating the indicator system of the space information system through the simulation system to obtain various indicator data specifically includes the following steps: Step S301, designing a simulation system for a specific combat mission, establishing a combat plan, and simulating to obtain evaluation sample indicators; wherein the combat plan includes determining the weapons and equipment used in the combat process for a specific combat mission, and determining the reconnaissance satellite platform, communication satellite platform, navigation satellite constellation and / or attack weapon components required for the combat in combination with specific relevant information and combat reality.

[0048] In this embodiment, in step S301, the weapons and equipment used in the combat process are determined for a specific combat mission. In order to ensure the acquisition of specific simulation data, the reconnaissance satellite platform, communication satellite platform, navigation satellite constellation and attack weapons used in the support plan are determined in combination with specific relevant information and combat reality. In a specific embodiment, the specific components can be referred to as shown in Table 1 and Table 2:

[0049] Table 1. Specific composition of weapons and equipment

[0050]

[0051] Table 2 Satellite orbit parameters

[0052]

[0053] In this specific embodiment, in order to realize the combat performance analysis of various weapons and equipment of the space information system, for the above weapon list, and considering that the evaluation object is a space-based information support equipment system, different types of satellites are involved, and the number of different types of satellites is changed. The selection strategy for navigation satellites is no failed satellites, 3 failed satellites, and 6 failed satellites, so as to evaluate the impact of navigation satellite positioning capabilities on the completion of combat missions. For optical reconnaissance satellites, electronic reconnaissance satellites, and SAR reconnaissance satellites, different combat plans are formed by extracting a fixed number of satellites to participate in combat. Therefore, a total of 1,200 combat plans are set as shown in Table 3:

[0054] Table 3: Composition of combat plans

[0055]

[0056] The mission target area is clearly defined as the activity area of ​​the blue party's ships, including the ocean and island environments. The activity time is 120 hours. The underlying indicator data is obtained through joint simulation of STK and MATLAB. The specific simulation steps are as follows:

[0057] (1) Use MATLAB to connect to MATLAB to build the initial scene, where the parameters of various satellites and their payloads refer to Tables 1 and 2.

[0058] (2) Implement simulation calculations of different schemes in Table 3 in STK through MATLAB, and save the indicator data of each scheme.

[0059] (3) The collected indicator data are normalized to obtain the final underlying indicator data as shown in Table 4.

[0060] Table 4. Indicator values ​​of the operational plan

[0061]

[0062]

[0063] Step S4: determine and divide the subsystems included in the spatial information system according to the evaluation sample indicators, determine the causal relationship between the spatial information system and the subsystems in the combat process, and construct a causal relationship diagram.

[0064] In this embodiment, according to the above steps, the determination of each subsystem can determine the capability requirements according to the components determined in the above step S301, and determine the subsystem supporting each capability.

[0065] In this embodiment, the space information system can be subdivided into four parts according to the capabilities: reconnaissance and surveillance system, early warning detection system, satellite navigation and positioning system, and satellite communication system. The situation awareness system composed of the above four parts is responsible for the acquisition, processing and distribution of battlefield situation information, and divides the combat units into firepower strike system and command and control system, and describes the relationship between each subsystem in terms of information transmission direction.

[0066] by Figure 4 For example, Figure 4 By analyzing the combat process shown in the figure, it can be found that the four parts of the space information system are mainly involved in the firepower strike mission, namely reconnaissance and surveillance, satellite navigation and positioning, and satellite communications. According to the capabilities, they are divided into reconnaissance and surveillance capabilities, navigation and positioning capabilities, and communication support capabilities. The attack system corresponds to the firepower strike capability. Through simple analysis, it can be found that the firepower strike capability of the attack system will be affected by factors such as reconnaissance and surveillance capabilities, navigation and positioning capabilities, and communication support capabilities, and the survival probability of the blue side’s ships will in turn have a negative impact on many of the red side’s subsystems. Based on this, the following can be drawn: Figure 5 A cause-and-effect diagram of the relationships between components of a system, with negative and positive feedback represented by arrows.

[0067] Step S5: construct a basic flow tree of each subsystem according to the index system of the spatial information system obtained in step S3, and construct an SD model according to the constructed cause-effect relationship diagram.

[0068] In this step, the SD flow rate basic tree modeling method is adopted. First, the system is divided into several subsystems and the models are constructed separately. Then, they are combined and connected according to the cause and effect relationship, which makes the modeling process simpler and more accurate, and improves the objectivity and accuracy of the empirical formula in the SD model.

[0069] Basic flow tree definition: If there is a point v(t) in a dynamic directed graph T(t) = (V(t), X(t)) such that any point u(t)∈V(t) in T(t) can find one and only one directed path from u(t) to v(t), then T(t) is called an in-tree. v(t) is called the root of the tree, u(t) that satisfies the in-degree d(u(t)) = 0 is called the tail of the tree, and the directed path from the tail of the tree to the root of the tree is called a branch. The number of nodes from the tail of the tree to the root of the tree is the branch length of this branch. If the rate variable is regarded as the root of the tree and the state variable is regarded as the tail of the tree, it can be called a flow tree. For details, please refer to the following. Figure 6 If the length of each branch is 1, the flow rate tree is called a basic flow rate tree.

[0070] In this embodiment, the SD model building steps are as follows:

[0071] (1) Analyze the spatial information system variables based on the cause-effect relationship diagram and determine the stock-flow variables, specifically,

[0072] {[L 1 (t),R 1 (t)],[L 2 (t),R 2 (t)]....[L n (t),R n (t)]};

[0073] Among them, L(t) is the stock, R(t) is the flow, and n is the number of subsystems;

[0074] (2) Divide the subsystems according to the spatial information system capabilities, and establish a basic flow rate tree for each subsystem, where the root of each tree is R i (t), the tail of the tree is L 1 (t) to L n (t),A 1 (t) to A n (t) and others are constants or auxiliary variables, as shown in the figure. Figure 7 As shown, it is a schematic diagram of the flow rate of the constructed subsystem provided in this embodiment;

[0075] (3) Combine and connect the sub-flow graphs according to the cause-effect relationship diagram to form the final stock-flow model.

[0076] Step S6: simulate the combat process through the constructed SD model, and calculate and determine the combat effectiveness based on the simulation result data to achieve combat effectiveness evaluation.

[0077] In this embodiment, the final combat effectiveness evaluation can be calculated by the weighted summation method to obtain the final effectiveness value, but the accuracy of the result obtained by this solution method is low. For example, Zhang Ziwei, Guo Qisheng, Dong Zhiming, etc. published a review of system combat effectiveness evaluation and optimization methods in the Journal of System Simulation in 2022. WS is the most commonly used method in multi-attribute decision making. As early as 1923, Edgeworth began to study the weighting problem in test statistics. This method determines the weight of each indicator according to the actual situation, and then obtains the comprehensive effectiveness value by the linear weighted average method. It shows that the weighted method is widely recognized.

[0078] In order to solve the problem of nonlinearity and uncertainty between indicators and combat effectiveness values ​​and accurately characterize the combat effectiveness of the space information system, this implementation will characterize the combat effectiveness from two aspects: time factor and anti-interference factor. The specific analysis is as follows;

[0079] In a specific embodiment, taking the space information system supporting fire strike as an example, the strike process includes the initial reconnaissance stage and the fire confrontation stage, and the space information system runs through the whole process. In order to accurately describe its combat effectiveness, the "kill chain of time-sensitive targets" will be used as a reference. It is a specific combat concept based on the concept of Observe-Orient-Decide-Act (OODA). The kill chain is divided into six stages: discovery, locking, tracking, positioning, engagement, and evaluation.

[0080] According to the above six stages, it can be found that the combat effectiveness of the space information system includes two aspects. On the one hand, it is reflected in the closed loop duration of the firepower strike kill chain under information support, and on the other hand, it is reflected in the anti-interference ability when facing the interference of the blue side. Therefore, the description of its combat effectiveness will start from the two aspects of time factors and anti-interference factors. Specifically,

[0081] The time factor represents the change in the completion time of the support vitality strike mission under different equipment parameter settings. Therefore, the time factor μ is defined as follows:

[0082]

[0083] Among them, T total is the duration of the operation, T is the time from the start of reconnaissance to the end of the strike, T will change with the change of equipment parameters, T best The time required to execute combat missions under the best combat scenario conditions.

[0084] Anti-interference factor: It indicates the anti-interference ability of the space information system under the blue side's anti-interference after the fire strike begins. The anti-interference factor η is defined as follows:

[0085]

[0086] Among them, F2 represents the information support capability value when the strike is completed, C23 is the standard line when the information support capability reaches the firepower strike standard, and F2 best Indicates the information support capability value when completing combat missions under the best combat scenario.

[0087] In this embodiment, in order to accurately characterize the combat effectiveness of the space information system in the process of performing combat tasks, the weights of the time factor and the anti-interference factor are set to 0.5, then β 作战效能 The calculation is as follows:

[0088]

[0089] In this embodiment, taking the visible light reconnaissance satellite as an example, four satellites are selected from five visible light imaging satellites to perform information support tasks, so as to analyze the impact of each satellite on the information support task. The remaining weapons and equipment are selected based on Scheme 400. Therefore, Schemes 25, 50, 75, 100, 125, and 400 are selected.

[0090] Table 5. Program settings

[0091]

[0092] Table 6. Combat effectiveness values

[0093]

[0094] Combined with the plan settings, satellites numbered G1 and G5 have a greater impact on the value of F2, and their impact on anti-interference capability is also the greatest when entering the combat confrontation phase. Therefore, improving the performance of satellites G1 and G5 can have greater benefits in improving the final information support capability.

[0095] The method provided by the present invention uses a task-based capability requirement analysis method to construct a task-oriented space information system combat effectiveness indicator system set, and on this basis, a domain mapping matrix is ​​used to establish a mapping from a task domain to an indicator domain, so that tasks and indicators are mapped, and by exploring the relationship therebetween, indicators are extracted from different tasks for rapid evaluation, and then a space information system simulation model based on system dynamics is established on the basis of the indicator system to realize the combat effectiveness evaluation of the space information system. The evaluation method can accurately reflect the nonlinearity and emergence of the space information system in the combat process by the method of system dynamics, so as to realize accurate and objective combat effectiveness evaluation.
