Description

Technical Field

[0001] The present invention belongs to the technical field of target threat assessment, and in particular relates to a target threat assessment method based on a large language model. Background Art

[0002] Threat assessment is the process of systematically analyzing and quantifying potential threats' capabilities, intentions, and potential harm. Its core is to provide a scientific basis for operational decision-making through the integration of multi-dimensional data. In modern simulated combat scenarios, accurate threat assessment is crucial for combat decision-making, directly impacting the scientific nature of command decisions and the effectiveness of combat.

[0003] Threat assessment is a multi-attribute decision-making problem that requires comprehensive consideration of the target's physical characteristics (such as speed and range) and tactical intent (such as heading angle and mission type). It includes both quantitative indicators (such as target range and speed) and qualitative indicators (such as stealth performance and mission type), which must be standardized through the Analytic Hierarchy Process (AHP) or membership functions. Threat assessments must be updated in real time to adapt to changes in the adversarial environment (such as target maneuvers and unexpected missions).

[0004] As adversarial environments become increasingly complex, traditional multi-attribute decision-making methods face challenges in coping with rapidly changing and multi-dimensional data, making them difficult to meet real-time adversarial demands. For example, data fusion complexity hinders the real-time integration and conflict resolution of heterogeneous data from multiple sources (radar, infrared, and electronic reconnaissance); incomplete adversarial environment information (such as target camouflage) leads to assessment bias; and threat assessment of large-scale target groups (such as drone swarms) requires low-latency computing, which relies on edge computing and distributed architectures.

[0005] Therefore, it is required to continuously optimize the threat assessment model to shift confrontation decisions from "experience-driven" to "data-driven" to improve response speed and accuracy. Summary of the Invention

[0026] Intelligent completion of missing values ​​and enhanced robustness: In cases of incomplete information or sensor failure, the model performs intelligent completion estimation based on historical databases, domain logic, and similar target data;

[0027] Adaptive adjustment of task situation: According to the task type, the weights of relevant indicators in the matrix are adjusted or partially reconstructed.

[0053] The present invention will be further described below with reference to the accompanying drawings, but the present invention is not limited in any way. Any changes or substitutions made based on the teachings of the present invention fall within the scope of protection of the present invention.

[0054] refer to Figure 1 The present invention provides a target threat assessment method based on the empowerment of a large language model, which is suitable for modern adversarial environments with complex information, multi-source heterogeneity and high real-time requirements. In order to effectively realize the rapid judgment and ranking of the threat levels of various targets, this embodiment first models the adversarial environment, integrates multi-dimensional information, including target performance, tactical background, environmental factors and command intelligence, and constructs a semantic evaluation space that can be processed by intelligent models. On this basis, combined with the intuitive fuzzy set TOPSIS method, quantitative threat assessment of multiple targets is carried out, and the automatic generation and dynamic optimization of evaluation indicators are realized through the large language model to improve the objectivity and efficiency of the evaluation process.

[0055] The core problem addressed by this application is how to efficiently construct a rational evaluation index system and quickly and accurately rank the threat levels of multiple potential targets in the context of complex data sources, diverse threat types, and rapidly changing adversarial scenarios. This invention uses a large language model to automatically extract key attributes from adversarial scenario semantic data and construct evaluation indicators. This method also utilizes an expert interaction mechanism for fine-tuning, forming a closed-loop optimization process to ensure the practicality and interpretability of the evaluation system.

[0056] refer to Figure 1 ,This invention first models the information environment involved in target threat assessment, and transforms the actual adversarial environment data into a structured semantic representation that can be understood and processed by the model.,This mainly includes three aspects:

[0057] 1. Target Information Modeling: Various adversarial targets (such as drones and electronic jamming equipment) are abstracted into objects with attributes such as firepower threat, mobility, and survivability. Each attribute is expressed in the IFS language to represent its credibility, unreliability, and uncertainty.

[0058] 2. Situational information modeling: including topography, electromagnetic interference, population density in the confrontation area, etc., are integrated into the model as evaluation influencing factors to construct environmental constraints and combat adaptability indicators.

[0059] 3. Mission Information Modeling: Extract semantic information such as command documents, tactical objectives, and confrontation intentions, establish a "mission-objective" mapping relationship, and enable the model to understand the tactical importance and mission relevance of the target.

[0060] Through the above-mentioned environmental modeling, the present invention transforms the traditional process of threat judgment that relies on expert experience into a semantic reasoning and quantitative evaluation process driven by a large language model, realizing the key transformation of threat assessment tasks from "experience-driven" to "intelligent empowerment."

[0061] Explanation of symbols

[0062]

[0063]

[0064] Problem Definition:

[0065] In this application, under the framework of the intuitionistic fuzzy set TOPSIS method, the part that needs to rely on expert experience is replaced by a large language model. There is a solution set T consisting of n solutions. In a certain adversarial environment, it is necessary to sort the threat values ​​of the n targets and determine which targets are high-threat targets and need to be processed first.

[0066] Set each target t in the target set T j Characterized by multiple attributes, the attribute values ​​are expressed as triples <μ ij ,v ij ,π ij >, where π ij represents the target t j It is uncertain whether there is a threat level under indicator j.

[0067] The target threat level ranking process proposed in this application is divided into the following steps: 1. Indicator generation (indicator weight estimation); 2. Construction of a decision matrix; 3. Expert review and optimization; 4. Calculation of the distance from each target to the positive and negative ideal solutions; 5. Threat ranking output.

[0068] The following, combined with the embodiments of the present invention, further details the indicator weight estimation and decision matrix construction process in the target threat assessment method enabled by a large language model. Unless otherwise specified, the following steps can be automatically executed by a computer system and can be integrated into the threat assessment device proposed in this invention.

[0069] S1 indicator generation

[0070] This paper proposes a threat assessment indicator generation method that integrates the intelligent perception capabilities of a large language model (LLM) with human-computer interaction mechanisms. This method offers the advantages of high automation, real-time updates, scalability, and auditability. This method aims to address the challenges of traditional threat assessment, such as the heavy reliance on expert experience, delayed updates, and difficulty covering heterogeneous data from multiple sources.

[0071] The present invention supports multi-source data input, and the data sources include but are not limited to:

[0072] Local static data: such as weapon and equipment performance parameter database, tactical regulations, historical threat assessment models, simulation confrontation results, etc.

[0073] Real-time dynamic data: such as information returned by the adversarial environment perception system, text summaries of drone reconnaissance images, and heterogeneous sensor data;

[0074] Open interconnected data: such as open source intelligence, online public opinion, online equipment information, Wikipedia knowledge base, etc.

[0075] By connecting to local databases and internet resources, the large language model can perform semantic analysis, feature extraction, and contextual association on large amounts of structured and unstructured information in seconds, automatically generating a threat assessment indicator system adapted to the current adversarial environment. This process integrates natural language understanding, contextual logical reasoning, and military domain knowledge transfer capabilities to construct a multi-level, multi-dimensional indicator structure covering core areas such as combat capability, tactical intent, environmental adaptability, and equipment coordination.

[0076] After the initial generation of indicators, this invention introduces an expert review and feedback mechanism to dynamically revise the indicator system through a "human-machine collaboration + closed-loop optimization" approach. Experts can provide modification suggestions for the effectiveness, quantifiability, and practical applicability of indicators based on current mission requirements. The model then rapidly adjusts the logical chain based on this feedback, forming a high-quality, highly consistent final indicator system.

[0077] Furthermore, the indicator generation mechanism constructed by this invention possesses continuous learning capabilities. The model can accumulate expert knowledge and self-optimize over multiple rounds of interaction, further reducing reliance on human intervention in subsequent tasks. Compared to traditional methods, this invention not only significantly improves the automation and intelligence level of indicator system construction, but also achieves rapid response, precise adaptation, and knowledge accumulation in indicator design through a "model generation - expert correction - model iteration" mechanism.

[0078] This indicator generation module breaks the shackles of "manual setting of indicators + application of fixed templates" in traditional threat assessment, and truly realizes a data-driven, intelligently evolved human-machine collaborative assessment system, providing a solid foundation for threat perception and intelligent decision-making in dynamic confrontation environments.

[0079] At the same time, the present invention proposes an indicator weight estimation method that combines the knowledge reasoning ability of a large language model and an expert feedback mechanism. The specific form and process are similar to the next step.

[0080] S2 builds a decision matrix

[0081] After completing the construction of a threat assessment indicator system and estimating indicator weights, this paper further proposes an efficient and scalable method for constructing a decision matrix to support subsequent threat ranking, situation analysis, and decision-making. This method combines the semantic parsing capabilities of a large language model for multi-source information with an expert feedback mechanism to construct an accurate, adaptable, and interpretable threat assessment decision matrix in dynamic and uncertain environments.

[0082] The decision matrix constructed by the present invention takes the target entity as the evaluation object and the generated multidimensional indicator system as the evaluation dimension. The matrix unit represents the quantitative score or qualitative judgment result of the target under specific indicators. Specifically, it includes the following key steps:

[0083] (1) Data collection and standardization: Target-related data is collected from local databases, environmental perception systems, Internet intelligence sources, and other channels. Normalization is performed on structured data, and semantic extraction, standard mapping, and quantitative scoring are performed on unstructured data (such as text descriptions and image summaries) using a large language model to ensure that data from different sources and formats can be compared on a unified scale.

[0084] (2) Multi-dimensional indicator filling mechanism: Based on the indicator system generated above, the large language model combines contextual information and target characteristics to fill in the target's evaluation value under each indicator item by item. For example, under the "firepower intensity" indicator, the model can integrate factors such as the enemy's weapon range, ammunition type, and strike accuracy to comprehensively calculate the score.

[0085] (3) Intelligent completion of missing values ​​and enhanced robustness: In cases of incomplete information or sensor failure, the model can perform intelligent completion estimation based on historical databases, domain logic, and similar target data to improve the integrity and anti-interference ability of the matrix.

[0086] (4) Expert verification and collaborative revision mechanism: After the preliminary matrix is ​​constructed, experts are allowed to review and revise the key indicator values ​​through the human-computer collaborative interface. The model automatically records the modified content and performs reverse knowledge update to optimize the subsequent filling strategy.

[0087] (5) Task situation adaptability adjustment: According to the task type, the weights of relevant indicators in the matrix are adjusted or partially reconstructed to enhance the tactical adaptability and accuracy of the decision-making results.

[0088] The final matrix is ​​weighted by the indicator weights and can be directly used as the input basis for the multi-attribute decision-making algorithm. It also supports customized needs. By modifying the prompt words, the large model can be given the ability to take into account the decision maker's preferences. Compared with the traditional matrix construction method that relies on static templates and manual form filling, this invention realizes the integration of data-driven, semantic understanding and human-computer collaborative construction, further consolidating the core decision-making foundation of the intelligent threat assessment system.

[0089] S3 expert review optimization mechanism

[0090] To ensure the practical relevance and professional credibility of threat assessment results, this paper proposes an expert review optimization mechanism that integrates expert knowledge feedback with the semantic reasoning capabilities of a large language model. By incorporating a "human-machine collaboration + closed-loop optimization" technical approach, this mechanism effectively improves the accuracy, adaptability, and interpretability of the assessment system.

[0091] refer to Figure 2 and Figure 3 After the evaluation process is initially completed, the indicator system, weight configuration and decision matrix automatically generated by the model will be presented to domain experts through a visual interface. Experts can review key evaluation factors item by item based on tactical mission requirements and confrontation experience. For indicator ambiguity, weight deviation or sorting anomalies in the model output, experts can directly propose revisions in natural language or in the form of structured suggestions. The present invention uses a semantic understanding module to identify the intent and perform structured analysis of the expert input content, and makes local adjustments to the model reasoning path to achieve rapid self-correction of the evaluation system.

[0092] The expert review process of this invention is not just a one-time modification; it also enables continuous optimization and knowledge accumulation. Each round of expert revisions is automatically archived, forming an internal "expert experience mapping archive" within the model. This archive drives the initial generation and judgment logic of the evaluation model in subsequent tasks, gradually building an intelligent evaluation system with continuous learning capabilities. This mechanism effectively reduces the reliance on continuous expert intervention, enabling the model to adapt to diverse environments and tasks while maintaining a high level of consistency and practicality.

[0093] Compared with the traditional threat assessment method led by experts and executed in a templated manner, the expert review optimization mechanism proposed in this invention takes the large model as the core and builds a set of efficient linkage mechanisms of "automatic generation - expert correction - model iteration", which greatly enhances the collaborative intelligence, dynamic adaptability and result interpretability of the threat assessment system.

[0094] S4 calculates the distance from each target to the positive and negative ideal solutions

[0095] This paper uses a multi-objective threat assessment model based on the IFS-TOPSIS method, allowing users to calculate the threat level of a target using multiple evaluation metrics. The method receives an evaluation matrix generated by a large model as input and includes steps such as determining positive and negative ideal solutions, calculating the distance of each target from the ideal solution, and finally ranking the threat levels. The specific steps are as follows:

[0096] (1) Definition of positive and negative ideal solutions

[0097] According to the method definition, the positive ideal solution A + and negative ideal solution A ―Represent the optimal and worst values ​​of all evaluation indicators respectively. Under each indicator, the membership and non-membership values ​​of the positive and negative ideal solutions are:

[0098]

[0099] in

[0100]

[0101] The membership degree of the positive ideal solution is obtained from the maximum score among the membership values ​​of the indicator. In one embodiment, the membership degree is the maximum value among the membership values ​​of the indicator. The non-membership degree is obtained from the maximum score among the non-membership values ​​of the indicator. The non-membership degree is the maximum value among the non-membership values ​​of the indicator. The purpose of this is to find the most "perfect" solution. The opposite is true for the negative ideal solution.

[0102] (2) Calculate the Euclidean distance from each target to the positive and negative ideal solutions

[0103] Distance to positive ideal solution

[0104]

[0105] Distance to negative ideal solution

[0106]

[0107] in

[0108]

[0109] S5 Threat Ranking Output

[0110] Based on the calculated distances between the positive and negative ideal solutions, the relative proximity of each target is calculated. The relative proximity reflects the degree of closeness between the target and the positive ideal solution. The formula is as follows

[0111]

[0112] The larger the relative proximity value is, the farther it is from the negative ideal solution, that is, the closer it is to the positive ideal solution, and the higher the threat level of the target.

[0113] Finally, all targets are ranked according to their relative proximity, from highest to lowest, to obtain the threat level of each target. Targets with higher threat levels have greater threat values ​​and should be prioritized. Through this ranking mechanism, the present invention can accurately assess the threat level of targets and provide a scientific basis for decision support.

[0114] By optimizing the decision-making process, the present invention achieves more efficient threat assessment in complex confrontation environments and provides decision makers with more valuable decision support.
