Description

Technical Field

[0001] The present invention relates to a main battle tank damage assessment method based on multi-index high-dimensional capability space volume comprehensive analysis, which can be applied to the field of main battle tank damage assessment, and provides a main battle tank capability degradation evaluation method for main battle tank designers and combat command decision makers, and also provides auxiliary reference for combat command decision makers in main battle tank damage assessment. Background Art

[0002] The damage of missiles to main battle tank targets is an extremely complex process, which involves the performance, structural characteristic parameters, etc. of the attacked target. How to accurately describe the degradation of main battle tank target capabilities is an important issue facing scientific researchers. With the gradual acceleration of the process of systematic combat, the assessment of main battle tank target capability degradation has received more and more attention. However, since the main battle tank is a comprehensive system, the combat capability of the main battle tank (the state after damage) must be coordinated with the various capabilities of the main battle tank. Therefore, the assessment of combat capability after damage has received more and more attention.

[0003] In order to evaluate the vulnerability of main battle tanks after being hit, Yang Jun et al. conducted the "Construction of Functional Damage Tree for a Certain Type of Tank" and established a damage tree diagram through the deductive method. This is mainly used to realize the vulnerability analysis and simulation evaluation of tank targets based on the reduced-order state method. It only constructs a complete and reasonable functional damage tree, which is crucial for exploring the root causes of tank damage and conducting tank target vulnerability analysis, but fails to reflect its calculation process, and cannot quantitatively analyze and evaluate the amount of capability degradation of main battle tanks after being hit. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings and defects of the prior art and provide a method for quantitatively analyzing and evaluating the capability degradation of main battle tanks. The present invention provides a main battle tank damage assessment method based on multi-index high-dimensional capability space volume comprehensive analysis. The method is based on the relationship analysis between the components and capabilities of the main battle tank, and adopts the deductive method of the capability degradation graph to analyze the relationship between the components and capabilities of the main battle tank. By developing a high-dimensional space volume analysis method, the relationship between the damage status of each component and the capability degradation is effectively aggregated, thereby solving the information fusion problem of component capability degradation and obtaining a quantitative assessment of the capability degradation of the main battle tank.

[0005] In order to achieve the above tasks, the present invention proposes a main battle tank damage assessment method based on multi-index capability space geometric distance analysis, comprising the following steps:

[0006] Based on the practical experience of main battle tank damage assessment, for the damage of conventional main battle tanks, the number of components defined is generally no more than 30, and the weight of each component is 0.05-0.5; for the damage of main battle tanks, the number of components fused each time is no more than 7, and the value of the fusion component algorithm coefficient α is 0.5-0.9, which can obtain better damage results. At the same time, the commonly used anti-tank missiles use 3 to 6 rounds to cover the main battle tank's capability degradation from mild, severe to destruction.

[0022] Where α is the nonlinear adjustment coefficient of the fusion component algorithm. The information fusion algorithm (6) can quantitatively analyze and evaluate the degree of reduction in the main combat capability;

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] The main battle tank damage assessment method based on multi-index high-dimensional capability space volume comprehensive analysis provided by the present invention solves the information fusion problem of main battle tank component capability degradation, thereby achieving quantitative analysis and assessment of the main battle tank's combat capability degradation.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the present invention is further described in detail below with reference to embodiments and drawings.

[0030] The purpose of the present invention is to provide a main battle tank damage assessment method based on multi-indicator high-dimensional capability space volume comprehensive analysis. The method takes the damage of a certain type of main battle tank as an example, and evaluates the capability degradation of the main battle tank after the main battle tank is hit in a certain mission.

[0031] In order to achieve the above tasks, the present invention proposes a main battle tank damage assessment method based on multi-index high-dimensional capability space volume comprehensive analysis, comprising the following steps:

[0032] 1. A main battle tank damage assessment method based on multi-index high-dimensional capability space volume comprehensive analysis includes the following steps:

[0033] Step 1: Determine the representation method of damage assessment information and define related sets and variables: Assume that the main battle tank involved in the assessment is A = {a i |i=1,2,…,m},,a i is a certain damage to the main battle tank; the component set is E = {e j |j=1,…,n},e j is a component in the component set; the component weight set is w = {w j |j=1,…,n},w j It is component e j The weight value of the evaluation object is U = {u j |j=1,…,n}, and u j With e j There is a corresponding relationship;

[0034] Among them, m = 4 (for four damage conditions), when the first capability degradation fusion, n = 20 (for example Figure 4 As shown, it is the lowest level component in the main battle tank component system (main gun, chassis, navigation system, three-defense device, etc.);

[0035] Step 2: The relationship between the damage state of the evaluated component and the damage state of its subordinate components is expressed as

[0036] U=f(u1,u2,…,u j ,…,u n ) (2)

[0037] And the remaining capacity values ​​of the component and its subordinate components satisfy:

[0038]

[0039] Take u1,u2,…,u j ,…,u n Construct an n-dimensional coordinate system for the coordinates, n is the number of component state fusions, then all possible damage states of the component correspond to points in the n-dimensional coordinate system, and these points constitute the state space describing the component damage state [U min ,U max ] n ; Let any state of the component be U(a i ), then in the state space, it corresponds to U(a i ) is the point (u i1 ,u i2 ,…,u ij ,…,u in ); when U(a i ) is the remaining capacity value of the component after being damaged, U max With U(a i ) The distance d(a) between the corresponding points i ) can be used to represent the similarity between any damaged state and the normal state of a component; then in n-dimensional space, U max As the center of the circle, with d(a i ) is a high-dimensional sphere with radius (1 / 2 n )Volume V i The degree of damage to the component is measured, that is, the reduction in the combat capability of the component due to damage U max ﹣U(a i );

[0040] Step 3: The distance d(a) between any damaged state of the component and the corresponding point in the normal state i ), in the form of Euclidean distance

[0041]

[0042] Among them, w j is the weight of the jth component.

[0043] Step 4, we can get the (1 / 2 n )Volume V i for

[0044]

[0045] in, is the Γ function, and its specific form is

[0046] Step 5, the remaining combat capability of the main battle tank after being damaged can be expressed as:

[0047]

[0048] Where α is the nonlinear adjustment coefficient of the fusion component algorithm, and the value of α is 0.8. The information fusion algorithm of formula (6) can quantitatively analyze and evaluate the degree of reduction in the main combat capability;

[0049] Depend on Figure 1 As can be seen from formula (4), the algorithm proposed in this invention takes the distance factor into consideration when integrating the residual capabilities of each component, and each distance is calculated in the form of weighted distance. Therefore, this algorithm tends to be a compromise. When no serious damage event occurs, the residual combat capability generated by the integration will tend to be in the direction of less damage, which also reflects the robustness of the vitality of the system.

[0050] For the four types of damage assessments of a main battle tank, the experts further evaluated the capacity values ​​of each damaged component based on the description of each damage situation. After obtaining the quantitative description of the damage situation by the experts, the numerical values ​​of the damage situation of each component are substituted into equations (4) and (5), and the residual capacity value u for the degradation of the capacity of each component of the main battle tank can be obtained. i As shown in Table 1.

[0051] Table 1 Remaining capacity values ​​of each component of main battle tank after degradation

[0052]

[0053] Combination Figure 4 , substitute the residual capability evaluation data of each component in Table 1 into formula (6), and take α as 0.8 according to the historical experience of this embodiment. Finally, the residual capability value result U of the main battle tank combat capability and the capability degradation of each combat sub-capability can be obtained. The residual capability value of each combat sub-capability degradation is shown in Table 2.

[0054] Table 2 Remaining capability values ​​of each combat sub-capability degradation

[0055]

[0056] Analyzing the remaining capacity values ​​of the above main battle tanks after each capacity degradation, we can know that:

[0057] a. In Case 1, the main battle tank is in a state of serious damage. The remaining capacity value of the ability degradation is 0.5304, but it has a certain degree of repairability;

[0058] b. In Case 2, the main battle tank was slightly damaged. The remaining capability value of capability degradation was 0.9022, which was slightly degraded. It could continue to perform most combat missions, but its performance of biological and chemical missions was seriously affected;

[0059] c. In Case 3, the main battle tank is slightly damaged. The remaining capability value of capability degradation is 0.9872, and the combat capability is basically in good condition, and it can continue to perform all combat missions;

[0060] d. In Case 4, the main battle tank is in a destroyed state. The remaining capacity value of the degraded capacity is 0, and it cannot be repaired.

[0061] The reasons for the above damage assessment conclusions are analyzed. Case 2 and Case 3 are in a state of mild capability degradation, and the residual capability values ​​of capability degradation are 0.9022 and 0.9872 respectively. From the capability degradation values ​​of each system of the main battle tank in Table 1 and Table 2, it can be seen that the reasons for the four damage assessment results are very different. In Case 4, the mobility and communication and command capabilities of the main battle tank are not in a serious capability degradation, and the defense capability is almost not degraded. However, because the main gun of the main battle tank was severely damaged, the main battle tank could no longer support the firepower strike capability. This shows that the main battle tank has suffered a fatal damage incident and it is difficult to repair in a short time. Therefore, the main battle tank is in a destroyed state. The firepower strike capability of the main battle tank in Case 1 is basically intact, which means that the main battle tank has not suffered a fatal damage incident. However, due to the serious damage to the main battle tank's mobility system, the overall combat capability of the main battle tank has been seriously reduced. In Table 1, the reduced capability of the components of the mobility system in Case 1 limits the firepower strike capability. Therefore, although the main battle tank is in a serious state of damage, it is possible to repair it because important components such as the main gun are not destroyed.

[0062] In both Case 2 and Case 3, the main battle tanks were in a state of slight capability degradation, which means that they can still perform most combat tasks at this time. In both Case 2 and Case 3, the various functional systems of the main battle tanks can continue to play a certain role, which means that no fatal damage has occurred to the main battle tanks. In Case 2, the communication and command system and the fire strike system of the main battle tank were slightly damaged, but from the analysis of Table 1, it can be seen that the three-defense device of the main battle tank was seriously damaged. Therefore, although the main battle tank can still continue to perform most combat tasks, tasks involving nuclear and biological and chemical weapons need to be performed with caution, otherwise it will affect the life safety of personnel. In Case 3, only the weapon system and the mobility system of the main battle tank were slightly damaged, and the status of the mobility system was better than that of the mobility system and the communication and command system of the main battle tank in Case 2, but the fire extinguishing and explosion suppression device of the main battle tank in Case 3 was damaged, so the response capability was weakened when facing damage from weapons such as incendiary bombs. However, most of the components of the main battle tank are in good condition, so the main battle tank is only in a state of slight damage.
