Description

Technical Field

[0001] The present invention relates to the technical field of combat system assessment, and in particular to a method and device for assessing system resilience in the face of continuous interference. Background Art

[0002] A combat system is a higher-level entity composed of interdependent and interacting combat entities that achieve specific combat missions. Completing these missions primarily involves two objectives: protecting one's own combat system and disrupting the enemy's. Combat system resilience embodies these characteristics and serves as an indicator of the system's overall performance. A reasonable and accurate assessment of combat system resilience is crucial for improving survivability, combat capability, and optimizing system architecture. However, existing combat system resilience assessments focus on evaluating the resilience of the same combat system under different perturbations or recovery activities, making it difficult to compare the resilience of multiple combat systems.

[0045] Figure 1 The figure is a flowchart of a system resilience assessment method for continuous interference.

[0046] Figure 2 This is a performance curve diagram when the combat system's combat network is attacked or interfered with.

[0047] Figure 3 This is a structural diagram of a system resilience assessment device for continuous interference. DETAILED DESCRIPTION

[0048] The embodiment of the present invention provides a system resilience assessment method for continuous interference. The system resilience assessment method for continuous interference of the embodiment of the present invention is applied to the server. Figure 1 As shown in Figure 1, a system resilience assessment method for continuous disturbances includes:

[0049] The first step is to obtain the current number of mission tasks and the composition of the combat system, and build a combat system combat network model based on the combat ring. The nodes in the combat network are combat entities, the combat ring contains multiple combat entities, and the combat network contains multiple combat rings.

[0050] In this step, the combat system consists of the types, number, performance, and inter-entity relationships of combat entities. Combat entities can be divided into four categories based on their purpose: reconnaissance entities, decision-making entities, strike entities, and target entities. The number of target entities is equal to the number of mission tasks. A combat loop is a closed loop formed by reconnaissance entities, decision-making entities, strike entities, and enemy targets in the combat system to complete a specific mission task. There are six types of inter-entity relationships: target reconnaissance relationships, information sharing relationships, intelligence transmission relationships, combat coordination relationships, command and decision-making relationships, and target strike relationships. Entity nodes are abstracted as nodes in the combat network, and inter-entity relationships are abstracted as directed edges in the combat network. A combat network model for the combat system based on the combat loop is established.

[0051] The second step is to evaluate the combat system's combat network performance based on the number of combat rings and combat ring performance in the combat network, and obtain a combat system's combat network performance curve that changes over time. The combat ring performance is calculated based on the number of combat entities in the combat ring and the standard length of the combat ring.

[0052] In this step, the performance of the combat loop is calculated first. The combat loop contains many combat entities, and the performance of the combat loop can be rated by evaluating the number of combat entities in the combat loop and the standard length of the combat loop.

[0053]

[0054] Where, f(p j ) represents the combat ring p j Performance,|p j |Indicates combat ring p j Standard length, C Te Indicates the anti-reconnaissance capability of entity T, C S (v j ) represents the ability of the reconnaissance entity, C D (v j ) represents the ability of the decision-making entity, C I (v j ) indicates the ability to strike an entity.

[0055] Then, the performance of the combat system's combat network is calculated. The combat system's combat network contains numerous combat loops. Due to the different importance of different target entities in the combat system's combat network, the combat loops are weighted according to the weight of the target entity. The performance of the combat system's combat network at time T is calculated as follows:

[0056]

[0057] Where C(G) represents the performance of the combat system combat network, w irepresents the weight of the i-th target entity.

[0058] Then the performance curve of the combat system combat network that changes with time is obtained as follows:

[0061] The third step is to evaluate the degradation resilience of the combat system's combat network in the performance degradation stage and the recovery resilience in the performance recovery stage based on the performance curve. The degradation resilience is the ratio of the area under the performance curve after being hit to the area under the performance curve without being hit, multiplied by the robustness and resistance. The recovery resilience is the ratio of the area under the performance curve after being hit to the area under the performance curve without being hit, multiplied by the recovery degree and the probability of recovery time. A combat system's combat network resilience evaluation model is constructed based on the degradation resilience and the recovery resilience.

[0062] In this step, the combat system combat network resilience assessment model is:

[0063]

[0065] The degradation toughness is the ratio of the area under the performance curve after being struck to the area under the performance curve without being struck multiplied by the robustness and resistance, specifically as follows:

[0069] Where α represents robustness, n(T r ) indicates T r The number of combat rings in the combat system at any moment, n(T a ) indicates T a The number of combat rings in the combat system at any given moment.

[0070]

[0071] Where β represents resistance, P baseline Represents the mission baseline performance value of the combat system combat network.

[0072]

[0073] Where: R d represents the degradation resilience of the combat system’s combat network, Δ S1 It represents the ratio of the area under the performance curve after the attack or interference to the area under the performance curve without the attack, α represents the robustness, and β represents the resistance.

[0074] The recovery toughness is the ratio of the area under the performance curve after the impact to the area under the performance curve without the impact multiplied by the recovery degree and the probability of recovery time, specifically as follows:

[0075]

[0076] Where, Δ S2 It represents the ratio of the area under the performance curve after recovery to the area under the performance curve before the impact, T e Indicates the moment when the combat system combat network completes recovery.

[0077]

[0078] Where μ represents the recovery degree, P(T e ) indicates T e The performance of the real-time combat system.

[0079]

[0080] Where, P(T re ≤T * ) represents the probability of recovery time, p is the probability of recovery, n f is the number of nodes destroyed when starting recovery, T N For recovery time.

[0081]

[0083] The fourth step is to calculate the resilience of the combat system under continuous interference based on the combat system combat network resilience assessment model.

[0084] In this step, the resilience of the combat system is:

[0085]

[0086] Among them, R(T) represents the resilience of the combat system, TS i Indicates the duration of the i-th time slice.

[0087] According to the above-mentioned system resilience assessment method for continuous interference, an embodiment of the present invention further provides a system resilience assessment device for continuous interference, as shown in the attached Figure 3 As shown, the device includes:
