[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] The purpose of this application is to provide a single-install firepower strike capability evaluation method and equipment based on FAHP to improve the scientificity, authenticity and accuracy of the single-install firepower strike capability evaluation.

[0042] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] In an exemplary embodiment, Figure 1 As shown, a single-unit firepower strike capability evaluation method based on FAHP is provided, including the following steps 1 to 10.

[0044] Step 1: Establish a single-install firepower strike capability assessment index system; the single-install firepower strike capability assessment index system includes a target layer, multiple first-level evaluation indicators and multiple second-level evaluation indicators.

[0045] Single-mount firepower strike capability is a modern military force with strong firepower damage capability, coordinated combat capability, rapid response capability, and battlefield adaptability. It is one of the important forces in modern warfare. Specifically, single-mount firepower strike capability refers to the ability of ground assault forces to carry out firepower strikes on targets in different combat environments using a single vehicle's artillery, machine guns, information equipment, reconnaissance equipment, fire control systems, protective devices, mobile devices and other types of weapons and equipment. It mainly includes firepower damage capability, coordinated combat capability, rapid response capability, and battlefield adaptability, such as Figure 2 shown.

[0046] Among them, firepower destructive capability means that the main gun, ammunition, fire control system and other elements of a single tank must be coordinated with each other, have a certain firepower strike capability, and be able to effectively strike the enemy on the battlefield. Rapid response capability means that a single tank should have a rapid response capability, be able to quickly deploy after receiving a combat order, quickly reach the combat position and immediately start to strike the enemy. Cooperative combat capability means that a single tank should have a certain cooperative combat capability, be able to cooperate with other single tanks, infantry, mechanized forces, etc., and jointly complete combat tasks. Battlefield adaptability means that a single tank should have a certain battlefield adaptability, and be able to adapt to different combat needs in different combat environments, such as different terrains and climatic conditions such as mountains, deserts, and cities.

[0047] The single-mounted equipment of a single-mounted weapon system refers to the main weapons and equipment on a single vehicle of a ground assault force, which directly determines the firepower strike capability of the single vehicle. Establishing an index system is the basic work for evaluating firepower strike capability. As an evaluation standard for the single-mounted firepower strike capability of ground assault forces, it plays an important role in the evaluation and is directly related to the rationality and accuracy of the evaluation results. Therefore, when constructing an index system, it needs to be subdivided into multiple aspects to fully integrate the single-mounted strike capability.

[0048] The firepower strike capability of a single weapon system is usually evaluated based on the degree of damage that the ground assault force can cause to the target in a unit of time. The degree of damage can be divided into five levels: destruction, loss of firepower and mobility, loss of firepower strike capability, loss of mobility, and intact. The firepower strike capability of a single weapon system is comprehensively evaluated from the shooter using reconnaissance equipment to discover the target, select the type of ammunition, track and lock the target to launching one or more shells, the shells hitting the target, and causing different degrees of damage to the target.

[0049] In the embodiments of the present application, tanks are used as the main body to study the single-mounted firepower strike capability. Tanks are currently the main ground fire assault equipment. Factors that affect the firepower strike capability include region, personnel, environment, equipment conditions, etc. But in general analysis, the main determining factors are the projectile strike effect, shooting reaction time, and damage probability. Therefore, this application records the firepower strike capability as A, as the target layer of the single-mounted firepower strike capability evaluation index system. The first-level evaluation indicators of the firepower strike capability can be divided into projectile strike effect, shooting reaction time, and damage probability, which are recorded as B1, B2, and B3 respectively, forming the first-level evaluation index layer of the single-mounted firepower strike capability evaluation index system. Each first-level evaluation indicator can be divided into a number of sub-indicators, namely second-level evaluation indicators, which constitute the second-level evaluation index layer of the single-mounted firepower strike capability evaluation index system. Such as Figure 3 As shown in the figure, the secondary evaluation indicators of projectile strike effect can be divided into artillery shell type, artillery caliber, protection capability and environmental factors, which are recorded as C1, C2, C3 and C4 respectively; the secondary evaluation indicators of shooting reaction time can be divided into reconnaissance capability, fire control system and tracking capability, which are recorded as C5, C6 and C7 respectively; the secondary evaluation indicators of damage probability can be divided into: shooting method, distance, combatant quality and mobility, which are recorded as C8, C9, C10 and C11 respectively.

[0050] Step 2: Establish an evaluation set according to the influence degree of the evaluation index; the evaluation set includes multiple evaluation levels.

[0051] FAHP is a decision analysis method that combines qualitative and quantitative methods. It is widely used in decision problem analysis, priority sorting, performance evaluation, etc. in various fields. The FAHP method is based on the membership theory of fuzzy mathematics. It realizes evaluation or decision-making through fuzzy judgment of pairwise comparison factors, and can better deal with uncertainty, imprecision and ambiguity. This application is based on the combat loop capability analysis of FAHP, integrating the reconnaissance, decision-making and strike in the combat loop into the process of the strike caused by a single weapon system on the target, and the comprehensive and objective evaluation is used to evaluate the capability of single-mounted firepower strike. The improved fuzzy comprehensive evaluation method evaluation model is an evaluation model based on the fuzzy hierarchical analysis method and the entropy method, which is used for multi-indicator and multi-factor evaluation. The model fully considers the importance of indicators and the discreteness of indicator values. The weight of the indicator is determined by the entropy method, and then combined with the fuzzy hierarchical analysis method for comprehensive evaluation.

[0052] First, an evaluation set is determined. In the embodiment of the present application, the evaluation results are divided into several levels, such as "destroyed", "lost both firepower and mobility", "lost firepower", "lost mobility" and "intact".

[0053] Specifically, according to the influence of the evaluation index, we can establish an evaluation set V = {v1, v2, ..., v m In this application, the evaluation set of the single-unit firepower strike capability of the ground assault force is defined as V = {destroyed, lost firepower and mobility, lost firepower, lost mobility, intact}, and the damage index corresponding to each evaluation level is 100, 90, 80, 60 and 0, respectively, as shown in Table 1 below.

[0054] Table 1 Evaluation set of single-unit firepower strike capability

[0055]

[0056] Therefore, in subsequent calculations, the evaluation set is substituted into V = {100, 90, 80, 60, 0} for calculation.

[0057] Step 3: Use the expert judgment method to analyze individual indicators, determine the degree of membership of each secondary evaluation indicator to each evaluation level, and establish a single factor evaluation set for each primary evaluation indicator.

[0058] This application uses the expert judgment method to conduct separate indicator analysis to determine each secondary evaluation indicator C i For each evaluation level v j The membership degree r ij , establish the fuzzy evaluation judgment matrix (also called evaluation matrix) R = {r ij}; where i = 1, 2, ..., n, n is the number of secondary evaluation indicators; j = 1, 2, ..., m, m is the number of evaluation levels included in the evaluation set; membership degree r ij It is indicator C i Rated v j The ratio of the number of times to the total number of experts. In the embodiment of the present application, n=11 corresponds to Figure 3 There are 11 secondary evaluation indicators C1 to C12 in the calculation. The i-th secondary evaluation indicator is represented as C i m = 5 corresponds to the five evaluation levels in Table 1. In the calculation, the jth evaluation level is represented as v j .

[0059] Specifically, experts in armored chassis, firepower, and single weapon systems were invited to study and judge the evaluation indicators of ground assault forces at all levels. Each factor level has a certain influence on the evaluation indicators of the evaluation set, which can be expressed by the membership function R i Denotes. Define factor u i (In this application, it is the secondary evaluation index C i ) for the evaluation level v j The membership degree is r ij , then the secondary evaluation index C i First-level evaluation index B i’ The single factor evaluation set is R i’ =(r i1 ,r i2 ,…r im ). By evaluating each factor, we can construct a fuzzy relation matrix from factor set U to evaluation set V, that is, fuzzy evaluation judgment matrix R = {r ij} n×m .

[0060] Split the corresponding rows of the fuzzy evaluation judgment matrix R to form each first-level evaluation index B i’ The single factor evaluation set R i’ ; where i'=1, 2, ..., n', n' is the number of primary evaluation indicators, and in the embodiment of the present application n'=3, corresponding to Figure 3 B1~B3 in . Then

[0061] Step 4: Compare each first-level evaluation index in pairs, judge its importance to the single-unit firepower strike capability, construct a first-level evaluation matrix and calculate the corresponding first-level weight vector.

[0062] Each first-level evaluation index B i’ , B j’Compare two by two to judge the importance of single-unit firepower strike capability A and construct a first-level evaluation matrix R A-B And calculate the corresponding first-level weight vector W A-B ; wherein i', j' = 1, 2, ..., n'. In the embodiment of the present application, n' = 3.

[0063] Specifically, for target A, by comparing factors (here, primary evaluation indicators) B1, B2, and B3 in pairs and selecting scale a according to the rules shown in Table 2 ij , as the first-level evaluation matrix R A-B The corresponding element r in i’j’ , establish the first-level evaluation matrix R A-B .

[0064] Table 2 Scales and their meanings

[0065]

[0066] Each first-level evaluation index B i’ , B j’ When comparing two by two, the first-level evaluation index B i’ , B j’ Substitute for elements i and j to determine their scale a ij , then let the first-level evaluation matrix R A-B The corresponding element r in i’j’ =a ij , we can build a first-level evaluation matrix R A-B For example, if for target A, the probability of damage B3 is slightly more important than the projectile impact effect B1, then r 31 =a 31 =3, r 131 =a 13 =1 / 3.

[0067] According to the characteristic root λ of the judgment matrix max A consistency check is performed to verify whether the calculated weights are consistent with objective reality. The judgment criteria are: Where CI is the consistency test index, and N represents the order of the judgment matrix. When , it means that the relative importance of each factor to the target is consistent, that is, the consistency test is passed. After the consistency test is passed, the calculated weights can be used directly. Among them, RI is the random consistency index, which is a pre-calculated value that depends on the number of criteria.

[0068] After establishing the first-level evaluation matrix R A-B Then, the corresponding first-level weight vector W is calculated using formula (1) A-B :

[0069]

[0070] That is W A-B ={w i'}.

[0071] Step 5: Compare each secondary evaluation index with each other, judge the importance of the primary evaluation index, construct each secondary evaluation matrix and calculate the corresponding secondary weight vector.

[0072] Similarly, the first-level evaluation index B i’ Each secondary evaluation index C in i , C j Compare the two and judge the first-level evaluation index B i’ The importance of constructing each secondary evaluation matrix R Bi’-C And calculate the corresponding secondary weight vector W Bi’-C .

[0073] For example, for the first-level evaluation index B1, by comparing the factors (here are the second-level evaluation indicators) C1, C2, C3, and C4 in pairs and selecting the scale a according to the rules shown in Table 2 ij , as the secondary evaluation matrix R B1’-C The corresponding element r in ij , then we can establish the secondary evaluation matrix R B1’-C .

[0074] Similarly, for the first-level evaluation index B2, the scale a is selected by comparing the second-level evaluation indexes C5, C6, and C7 in pairs according to the rules shown in Table 2. ij , as the secondary evaluation matrix R B2’-C The corresponding element r in ij , then we can establish the secondary evaluation matrix R B2’-C .

[0075] For the first-level evaluation index B3, the scale a is selected by comparing the second-level evaluation indexes C8, C9, C10, and C11 in pairs according to the rules shown in Table 2. ij , as the secondary evaluation matrix R B3’-C The corresponding element r in ij , then we can establish the secondary evaluation matrix R B3’-C .

[0076] After establishing the secondary evaluation matrix R Bi’-C After that, the corresponding secondary weight vector W can be calculated using formula (2) Bi’-C :

[0077]

[0078] It should be noted that when using formula (2) to calculate the corresponding secondary weight, the value of n needs to be based on the primary evaluation index B i’ Secondary evaluation index C i For example, in the embodiment of the present application, for the secondary evaluation matrix R B1’-C , R B2’-C and R B3’-C , where n is 4, 3, and 4 respectively, the corresponding secondary weight vector W Bi’-C ={w i}.

[0079] Step 6: Multiply the secondary weight vector of each secondary evaluation matrix by the single factor evaluation set of each primary evaluation index to obtain the fuzzy set corresponding to each primary evaluation index.

[0080] Formula (3) can be used to calculate each first-level evaluation index B i’ The corresponding fuzzy set R Bi’ :

[0081] R Bi’ =W Bi’-C ·R i’ (3)

[0082] Step 7: Construct a comprehensive weight matrix based on the fuzzy sets corresponding to each primary evaluation index.

[0083] The comprehensive weight matrix is:

[0084]

[0085] Step 8: Multiply the first-level weight vector corresponding to the first-level evaluation matrix by the comprehensive weight matrix to obtain the target layer evaluation result.

[0086] The target layer evaluation result H can be calculated using formula (5):

[0087] H=W A-B ·R (5)

[0088] Step 9: Calculate the comprehensive evaluation score based on the target layer evaluation results.

[0089] The comprehensive evaluation score S can be calculated using formula (6):

[0090] S=H·V T (6)

[0091] Where V = {100, 90, 80, 60, 0}, and T represents transpose.

[0092] Step 10: Evaluate the firepower strike capability of the single weapon system based on the comprehensive evaluation score.

[0093] The comprehensive evaluation score S is compared with the elements in V = {100, 90, 80, 60, 0}, and the evaluation level of the single-mounted weapon system's single-mounted firepower strike capability can be determined according to the maximum membership principle. For example, when S = 75.67 is calculated, according to the maximum membership principle, its firepower strike capability is evaluated as being able to cause the enemy to lose its firepower strike capability (V = 80).

[0094] This application is based on the strike effect of single-mounted weapon systems in actual war environments, and takes the degree of damage to the target from discovering the target to firing one or more shells in a unit time as the basis for evaluating the strength of the single-mounted firepower strike capability of the ground assault force. The fuzzy analytic hierarchy process (FAHP) is used to evaluate each stage of tank combat from discovering the target to tracking and aiming at the target to destroying the target. An evaluation model for the single-mounted firepower strike capability of the ground assault force is established, which enhances the authenticity of combat simulation, improves the scientificity, authenticity and accuracy of the evaluation of the single-mounted firepower strike capability, and can effectively assist grassroots armored unit commanders in simulating war processes and decision-making.

[0095] A specific implementation process of the present application method is provided below.

[0096] During a red-blue confrontation in a certain position attack, the blue army dispatched a certain type of infantry fighting vehicle to the front of the position to conduct reconnaissance, warning and strike missions. At a certain moment, the enemy infantry fighting vehicle was stationary in the bunker, investigating the battlefield situation and obtaining data through sensors, including artillery model, caliber, effective range, speed, type of ammunition carried, location and other information. The specific evaluation method is divided into three aspects: using expert judgment method to analyze individual indicators to determine the impact of individual influencing factors on the degree of damage; collectively analyzing multiple indicators to determine the combined impact of multiple influencing factors on the degree of damage; analyzing the results of the comprehensive impact of multiple factors, summarizing the formula to link the influencing factors together, and comprehensively evaluating the single-mount firepower strike capability. The specific process is as follows:

[0097] S1: Establish a single-unit firepower strike capability assessment index system, such as Figure 3 As shown, the single-unit firepower strike capability evaluation index system includes a target layer A, multiple first-level evaluation indicators B1, B2, B3 and multiple second-level evaluation indicators C1~C10.

[0098] S2: Establish an evaluation set according to the influence degree of the evaluation indicators, as shown in Table 1, V = {destroyed, lost firepower and mobility, lost firepower, lost mobility, intact} = {100, 90, 80, 60, 0}.

[0099] S3: Use the expert judgment method to analyze individual indicators, determine the degree of membership of each secondary evaluation indicator to each evaluation level, and establish a single factor evaluation set for each primary evaluation indicator.

[0100] Ten experts evaluated the single-factor secondary evaluation indicators that affect the single-unit firepower strike capability and calculated the corresponding membership degree r ij , r ij It is indicator C i Rated v j The ratio of the number of times to the total number of experts. According to the evaluation of each secondary evaluation index by the expert members, the expert evaluation results are shown in Table 3. The elements in Table 3 are the fuzzy evaluation judgment matrix R = {r ij} in the corresponding element.

[0101] Table 3 Expert evaluation results of individual indicator analysis

[0102] <![CDATA[r ij ]]> C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C11 100 0.2 0.3 0.1 0 0 0.3 0.3 0.3 0.5 0.1 0.4 90 0.3 0.4 0.2 0.2 0.2 0.4 0.3 0.5 0.4 0.4 0.4 80 0.3 0.2 0.3 0.4 0.5 0.2 0.2 0.2 0.1 0.3 0.1 60 0.2 0.1 0.3 0.2 0.2 0.1 0.2 0 0 0.1 0.1 0 0 0 0.1 0.2 0.1 0 0 0 0 0 0

[0103] Split the corresponding rows of the fuzzy evaluation judgment matrix R to form each first-level evaluation index B i’ The single factor evaluation set R i’ , as follows:

[0104]

[0105] S4: Compare each first-level evaluation index pairwise to judge its importance to the single-unit firepower strike capability, construct a first-level evaluation matrix and calculate the corresponding first-level weight vector.

[0106] Each first-level evaluation index B i’ , B j’ Compare two by two to judge the importance of single-unit firepower strike capability A and construct a first-level evaluation matrix R A-B And use formula (1) to calculate the corresponding first-level weight vector W A-B , as shown in Table 4 below:

[0107] Table 4 First-level evaluation matrix R A-B And the corresponding first-level weight vector W A-B

[0108]

[0109] Then W A-B =(0.249 0.157 594), the weight value corresponding to each row is obtained by multiplying the product of each row to the cube, and then normalizing it, see formula (1).

[0110] S5: Compare each secondary evaluation indicator in pairs, judge the importance of the primary evaluation indicator, construct each secondary evaluation matrix and calculate the corresponding secondary weight vector.

[0111] The first-level evaluation index B i’Each secondary evaluation index C in i , C j Compare the two and judge the first-level evaluation index B i’ The importance of constructing each secondary evaluation matrix R Bi’-C And calculate the corresponding secondary weight vector W Bi’-C , as shown in Tables 5 to 7 respectively.

[0112] Table 5 Secondary evaluation matrix R B1’-C And the corresponding secondary weight vector W B1’-C

[0113]

[0114] Then W B1’-C =(0.540 0.255 0.088 0.117), the weight value corresponding to each row is obtained by multiplying the product of each row to the fourth power and then normalizing it, see formula (2).

[0115] Table 6 Secondary evaluation matrix R B2’-C And the corresponding secondary weight vector W B2’-C

[0116]

[0117]

[0118] Then W B2’-C =(0.630 0.219 0.152), the weight value corresponding to each row is obtained by multiplying the product of each row to the cube, and then normalizing it, see formula (2).

[0119] Table 7 Secondary evaluation matrix R B3’-C The secondary weight vector W B3’-C

[0120]

[0121] Then W B3’-C =(0.453 0.289 0.107 0.151), the weight value corresponding to each row is obtained by multiplying the product of each row to the fourth power and then normalizing it, see formula (2).

[0122] According to the calculation results, it can be seen that the consistency ratio CR of each evaluation matrix is ​​less than 0.1, which fully meets the consistency test requirements.

[0123] S6: Multiply the secondary weight vector of each secondary evaluation matrix by the single factor evaluation set of each primary evaluation index to obtain the fuzzy set corresponding to each primary evaluation index.

[0124] The fuzzy set corresponding to each first-level evaluation index is calculated as follows:

[0125] R B1’ =W B1’-C ·R 1’ =(0.193 0.305 0.289 0.016 0.012)

[0126] R B2’ =W B2’-C ·R 2’ =(0.286 0.260 0.389 0.178 0.063)

[0127] R B3’ =W B3’-C ·R 3’ =(0.352 0.445 0.167 0.042 0)

[0128] S7: Construct a comprehensive weight matrix based on the fuzzy sets corresponding to each primary evaluation index:

[0129]

[0130] S8: Multiply the first-level weight vector corresponding to the first-level evaluation matrix by the comprehensive weight matrix to obtain the target layer evaluation result.

[0131] Based on the results of the first-level evaluation, further evaluation of the single-unit firepower strike capability is carried out:

[0132] H=W A-B ·R=(0.326 0.354 0.216 0.094 0.013)

[0133] S9: Calculate the comprehensive evaluation score based on the evaluation results of the target layer:

[0134] S=H·V T =75.67

[0135] S10: Evaluate the firepower strike capability of a single weapon system based on the comprehensive evaluation score.

[0136] According to the comprehensive evaluation score S=75.67, according to the principle of maximum membership, it can be seen that the firepower strike capability of a single piece of ground assault equipment is evaluated as being able to cause the enemy to lose its firepower strike capability, indicating that the firepower strike capability of the evaluated ground assault equipment is relatively high.

[0137] This application establishes a ground assault force single-mount firepower strike capability assessment model based on FAHP. As an effective military assessment tool, it can scientifically assess and control military systems, and can be used to improve combat simulation software such as weapon deduction and computer simulation, so as to make the deduction results closer to actual combat, assist commanders in making correct decisions, and help improve combat effectiveness. At the same time, this model mainly studies the single-mount firepower strike capability based on tanks and armored vehicles. After the model is established, through experimental analysis and modification of the parameters, the purpose of air, sea, and long-range firepower strike capabilities can be evaluated. By combining this model with artificial intelligence, it can also enable the weapon system to autonomously carry out combat missions and promote the intelligentization of weapons and equipment.
