Description

Technical Field

[0001] This invention belongs to the field of military command and control and combat simulation technology, and relates to a method for rapid recovery and reconstruction of a kill network after being subjected to a local attack, especially a method for rapid local reconstruction of a kill network based on a network replenishment strategy. Background Technology

[0002] As a new operational concept, the military kill network forms a resilient and adaptive operational system by dynamically interconnecting heterogeneous nodes for reconnaissance, command, and strike, in order to cope with highly dynamic and highly contested battlefield environments. However, during combat, critical nodes and links of the kill network are susceptible to local failure due to enemy attacks, which can lead to the interruption of critical mission links, affecting operational continuity and system effectiveness.

[0003] Existing methods for reconstructing damaged kill networks mostly employ a "global reconstruction" paradigm, which involves re-optimizing and generating a new network structure within the global solution space. While these methods can theoretically achieve global optimality, they are typically computationally complex and time-consuming, making them unsuitable for real-time battlefield decision-making. Furthermore, global reconstruction often disrupts the existing collaborative relationships and structural advantages of the original network, leading to unnecessary reconfigurations of operational organization and command and control processes, thus reducing recovery efficiency. For these reasons, there is an urgent need for a localized, rapid reconstruction method capable of quickly restoring the kill network's operational capabilities after damage, while preserving as much of the original network's healthy structural and mission information as possible. Summary of the Invention

[0011] S5: Evaluate the Pareto optimal solution set, determine the reconstruction plan to be executed based on the battlefield situation, perform network topology update, and complete the local reconstruction of the kill network.

[0012] Furthermore, the specific process of constructing the local repair zone includes the following steps:

[0024] S33. Minimize task completion delay:

[0025] ;

[0026] in, Indicates link transmission delay. Indicates task In the link The allocation decision variables.

[0027] Furthermore, the method for constructing the transformation matrix-guided TM-NSGA-III algorithm includes the following steps:

[0028] S41. Construct a functional substitution transition matrix between failed nodes and candidate nodes to characterize the confidence level of candidate nodes in functional substitution of failed nodes.

[0029] S42. Generate an initial population based on the functional substitution transformation matrix, prioritizing node combinations with high substitution confidence as initial solutions; where: the initial population generation process based on the transformation matrix is ​​as follows: Figure 2 As shown;

[0091] 1. Experimental scenario setup:

[0092] The initial kill network consists of 32 equipment entity nodes, including reconnaissance, decision-making, strike, and assessment types. A simulated blue team attack causes the red team's decision-making node C2 and strike node F1 to fail, triggering related link interruptions and forming a damaged network topology, such as...

[0111] 3. Experimental verification and result analysis:

[0112] To verify the proposed mesh replacement strategy and the rapid reconstruction capability and solution set quality advantage of TM-INSGA-III after the kill net is damaged, three comparative methods were set up for experiments: ① Global reconstruction-NSGA-III (denoted as G-NSGA-III), which re-optimizes within the global solution space; ② Mesh replacement strategy + standard NSGA-III (denoted as P-NSGA-III), which uses a local reconstruction model and repair zone constraints, but without transformation matrix guidance; ③ The TM-INSGA-III proposed in this invention. All three methods used the unified algorithm parameters shown in Table 2, ran independently 20 times, and the mean and standard deviation of hypervolume HV and inversion generation distance IGD were statistically analyzed.

[0113] Table 3 Comparison of solution set quality indicators for different algorithms

[0114] algorithm HV (mean ± standard deviation) IGD (mean ± standard deviation) G-NSGA-Ⅲ 0.612±0.018 0.093±0.007 P-NSGA-Ⅲ 0.734±0.012 0.076±0.005 TM-INSGA-III 0.8402±0.009 0.058±0.004

[0115] Experimental results show that the method proposed in this invention has significant advantages over the traditional global reconstruction method (G-NSGA-III) and the standard algorithm (P-NSGA-III) which only uses the repair region constraint, in terms of solution set quality (higher HV value and lower IGD value), convergence speed (faster rise of HV iteration curve) and scheme efficiency (able to recover all failed functions with lower average decision delay and reconstruction cost).

[0116] Ablation experiments further validated the effectiveness of the transformation matrix-guided initialization and directed mutation strategies. The baseline algorithm was set as P-NSGA-III, and four algorithm configurations were formed by progressively adding key modules to it:

[0117] A1 is P-NSGA-III, which uses a patching strategy to constrain the solution space, but the initial population is generated completely randomly, and the mutation is a standard discrete mutation.

[0118] A2 is the initial population guided by the P-NSGA-III+ transformation matrix. Based on A1, the transformation matrix is ​​used to generate some high-quality individuals to form the initial population.

[0119] A3 is a P-NSGA-III+ targeted mutation strategy. Based on A1, it only replaces the standard mutation with a targeted mutation, while keeping the rest the same.

[0120] A4 is TM-INSGA-III, which simultaneously enables the transformation matrix to guide the initial population and the directional mutation strategy.

[0121] A comparison of convergence of different algorithms on the HV metric, such as Figure 4 As shown; ablation experimental results under different algorithm configurations, such as Figure 5 and Figure 6 As shown in the figure; the experimental results show that A4 has better convergence speed and solution set quality than the other three configurations, proving the synergistic effect of transformation matrix-guided initialization and directional mutation strategy.

[0122] 4. Typical Restructuring Schemes

[0123] 1) Scheme A (Minimum Time Delay Scheme): To quickly restore the task loop, decision nodes C1 and C6 are selected to jointly replace the failed C2, and strike nodes M3 and SH1 are selected to jointly replace the failed F1. This scheme has a low decision latency (ATD) and can quickly generate a usable solution, such as... Figure 7 As shown.

[0124] 2) Option B (Lowest Cost Option): To reduce reconfiguration resource consumption, only decision node C1 is selected to replace C2, and only attack node M3 is selected to replace F1. This option has a lower average reconfiguration cost (ARC), such as... Figure 8 As shown.

[0125] Commanders can make a final decision among multiple Pareto solutions, such as Option A and Option B, based on the current battlefield urgency and resource availability.

[0126] Experimental results show that the proposed method has significant advantages over the traditional global reconstruction method (G-NSGA-III) and the standard algorithm using only repair region constraints (P-NSGA-III) in terms of solution set quality (higher HV value, lower IGD value), convergence speed (faster HV iteration curve rise), and scheme efficiency (able to recover all failed functions with lower average decision delay and reconstruction cost). Ablation experiments further demonstrate the effectiveness and synergistic effect of transformation matrix-guided initialization and directional mutation strategies in improving algorithm performance.

[0127] In summary, this invention effectively achieves rapid and high-quality local reconstruction of the kill net through forced localization of the local repair area, multi-target integrated optimization, and TM-INSGA-III intelligent search, providing a feasible technical approach to improve the resilience and self-healing capability of the kill net in dynamic battlefield environments.
