Description

Technical Field

[0001] The present invention relates to the technical field of contribution evaluation, and in particular to a method for evaluating the contribution of a system combat unit to a mission task. Background Art

[0002] At present, in the future new combat mode, in order to effectively coordinate and execute complex military operations, multiple military units and support resources will jointly form a comprehensive organizational structure for executing tasks in military operations, with the purpose of achieving specific military goals, forming an information system-based combat system. Among them, the system combat unit is the smallest tactical and technical coordination unit that independently carries out system combat operations, including military units, weapon systems and support resources. It is the organizational basis of the new combat system based on information systems. The system combat unit contribution evaluation is a method used to measure the contribution of different units in military operations to achieving overall military goals. This evaluation helps guide military decision-making, resource allocation and strategic planning to ensure the effectiveness and efficiency of the entire combat system.

[0003] The existing system contribution evaluation methods are mainly based on the combat effectiveness or capability index system of weapons and equipment and the network structure model. The system contribution of the members to be evaluated is obtained by comparing the comprehensive evaluation values ​​when the members to be evaluated are included and not included. (Reference papers "Wang Nan, Yang Juan, He Rong. Weapon equipment system contribution evaluation method based on rough set [J]. Command Control and Simulation, 2016, 38(01): 104-107.", "Luo Xiaoming, Zhu Yanlei, He Rong. Weapon equipment combat system contribution evaluation method based on SEM [J]. Journal of Equipment Academy, 2015, 26(05): 1-6.", "Zhao Danling, Tan Yuejin, Li Jichao, etc. Weapon equipment system contribution evaluation based on combat ring [J]. Systems Engineering and Electronic Technology, 2017, 39(10): 2239-2247.", Patent "Qi Xiaoqian, Mu Libo, Duan Tongle, etc. A command and control equipment system contribution evaluation method based on fuzzy hierarchical analysis [P]. Hebei Province: CN116307366A, 2023-06-23.", "Bi Wenhao, Zhou Jie, Zhang An, etc. Weapon equipment system contribution evaluation method based on combat ring [P]. Shaanxi Province: CN112417710B, 2022-09-27.") These system contribution evaluation methods have several defects: first, the evaluation object is weapons and equipment or capabilities, which cannot be applied to the contribution evaluation needs of diverse system combat units. In the evaluation process, they either focus on the combat effectiveness or capability of weapons and equipment, or focus on the network topology connection relationship between weapons and equipment. It is necessary to conduct multiple system tests or simulation experiments to obtain the comprehensive evaluation value with and without the members to be evaluated, and then obtain the system contribution of the members to be evaluated. Summary of the invention

[0004] The purpose of the present invention is to provide a method for evaluating the contribution of system combat units to mission tasks, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for evaluating the contribution of system combat units to a mission task, comprising the following steps:

[0007] Step 2: Based on the mission, determine the capability requirements of each system combat unit in the combat system network model, and use the capability requirement satisfaction model to measure the capability of the system combat unit. In the process of issuing tasks, the capability requirements meet all the problems in the execution of the mission, and the capability level of the system combat unit can meet the capability level required by the mission;

[0008] Step 3: Evaluate the actual capability of each system combat unit and the communication frequency between system combat units through system test, simulation test, exercise records and log data;

[0009] Step 4: Finally, the contribution of each system combat unit is calculated using the system contribution evaluation model. The system contribution of the system combat unit is mainly composed of two parts:

[0010] The contribution of the system combat unit to its own combat effectiveness The contribution of network communication of system combat units in the combat system .

[0011] Preferably, the specific steps of constructing the combat system network model in step 1 are as follows:

[0012] First, based on the mission, determine the various capability requirements to achieve the mission;

[0013] And match the capability requirements with the inherent capabilities of the system combat units, and select the system combat units as nodes in the combat system network model;

[0014] Finally, the transmission path of combat instructions and other information between the combat units of the system is used as the edge in the combat system network model;

[0015] Thus, we can get the combat system network model , among which, System Combat Unit Nodes that make up the network model , by direct information transmission paths between system combat units The edges in the network model ;Right now

[0016] .

[0017] Preferably, in step 2, a large-scale capability satisfaction model is adopted, assuming that the capability requirements of the combat system network model for each system combat unit are as follows:

[0018]

[0019] in, Indicates System Combat Unit No. Ability, and They represent the network model of the combat system for the System Combat Unit No. Abilities The minimum and maximum capacity requirements, The network model of the combat system System Combat Unit The number of capability requirement types.

It is the weighted sum of these two.

[0024] Optimum, and the combat effectiveness contribution of the system combat unit itself ;

[0025] In the combat system network model, each system combat unit contains multiple capabilities, and its combat effectiveness is obtained by weighted combination of the combat effectiveness of multiple capabilities.

Based on the frequency of direct communication between the combat units of the system, the transmission of combat command information is taken as the key consideration factor. The weighted PageRank algorithm is used to calculate the network communication contribution of the combat units of the system in the combat system. The detailed steps are as follows:

[0040] First, construct the weight matrix as follows

[0041]

[0042] in, For the System Combat Unit To System Combat Unit The communication importance weight is calculated as follows:

[0043]

[0044] Second, calculate the PageRank value of the system combat unit in the combat system network;

[0045] Since the frequency of system combat units sending combat instructions and other information in the combat system network communication is the main indicator of the importance of its network communication, the following formula is used to calculate the PageRank value of the system combat unit in the combat system network:

[0046]

[0047] in, For the The PageRank value of a system combat unit, For the The number of system combat units that send combat instructions and other information to the system combat unit. For the System Combat Unit To System Combat Unit The communication importance weight of is the damping coefficient. The above formula is expressed in matrix calculation as follows:
