Embodiment

In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.

As shown in Figure 1, if the design proposal of certain naval vessels has in N, the flow process selecting optimization design scheme exactly from N kind design proposal that Fig. 1 characterizes.In order to the method for optimizing of warship system design proposal is more clearly described, now provide the warship system design proposal of one group of hypothesis:

The speed of a ship or plane on certain type naval vessel is 30 joints, and armament systems allocation plan is as follows: (loss factor of warship canon is 0.001, and the loss factor of ship-to-ship missile is 0.003)

1, load 2 warship canons, striking distance is 50 nautical miles, detection range is 50 nautical miles; 1 ship-to-ship missile, striking distance is 100 nautical miles, and detection range is 80 nautical miles.

2, load 2 warship canons, striking distance is 50 nautical miles, detection range is 50 nautical miles; 1 ship-to-ship missile, striking distance is 100 nautical miles, and detection range is 100 nautical miles.

According to allocation plan 1 and scheme 2, fictionalize a blue party naval vessel and a red naval vessel respectively.In order to simplify computation process, provide following Combat scenario: establish two naval vessels to navigate by water in opposite directions, when target is in effective firing area of one's own side's armament systems, namely it is attacked.

The weapon configuration parameter on foundation Combat scenario and two naval vessels, infers its real belligerent process and should be divided into following 3 steps:

1, red naval vessel utilizes ship-to-ship missile to attack blue party naval vessel: the guided missile effective striking distance on red naval vessel is than the length 20 nautical miles on blue party naval vessel, the relative speed of a ship or plane on two naval vessels is 60 joints, calculate: at belligerent first 20 minutes, red naval vessel can utilize ship-to-ship missile to attack blue party naval vessel, and blue party naval vessel cannot be fought back.

2, blue party naval vessel, red naval vessel utilize ship-to-ship missile to accuse each other: the effective striking distance of the ship-to-ship missile on blue party naval vessel grows 40 nautical miles than the effective striking distance of warship canon, calculate: within the time period of 20-50 minute that both sides are belligerent, blue party naval vessel and red naval vessel can only utilize ship-to-ship missile to accuse each other.

3, blue party naval vessel, red naval vessel utilize ship-to-ship missile and warship canon to accuse each other: after belligerent 50 minutes of both sides, red naval vessel and blue party naval vessel have all entered within effective firing area of the other side's gun weapon, and blue party naval vessel and red naval vessel can utilize ship-to-ship missile and warship canon to accuse each other.

Use multivariable Lanchester equation and modified Lanchester equation dynamically to deduce belligerent process respectively, result of calculation as shown in Figures 2 and 3.In Fig. 3, top curve is the damage curve of red, and lower curve is the damage curve of blue party.

Comparison diagram 2 and Fig. 3 known: multivariable Lanchester equation have ignored the impact of space factor on operation result, cause the damage curve of red blue both sides just as, modified Lanchester equation describes the belligerent process on red naval vessel and blue party naval vessel more truly.According to the troops of both sides loss curve, the fighting efficiency of allocation plan 2 is higher than the fighting efficiency of allocation plan 1, and the exchange rate of platform is 0.6572:1, and this conclusion meets micro-judgment.

For ease of understanding, the warship system design proposal in the present embodiment is less, Combat scenario is relatively simple, but can reflect the process based on the warship system design proposal method for optimizing of deducing of fighting.

Be below the development of modified Lanchester equation in the present invention:

Multivariable Lanchester equation on the basis of classical Lanchester equation, suppose red have m class combat unit (participate in fight armament systems or optimal in structure), blue party has n class combat unit, its equation as shown in Equation 1:

$\left\{\begin{array}{c}\stackrel{\·}{Y}=-(A*\mathrm{\λ})X\\ \stackrel{\·}{X}=-(B*\mathrm{\θ})T\end{array}\right....\left(1\right)$

Wherein X=(x ₁..., x _m) ^t, Y=(y ₁..., y _n) ^t, x _i, y _jrepresent the quantity of red i-th class combat unit and the quantity of blue party jth class combat unit respectively; A=(a _ij), λ=(λ _ij) be n × m matrix, B=(b _ji), θ=(θ _ji) be m * n matrix, A, B are loss factor matrix, and λ, θ are Fire Distribution matrix; " * " representing matrix corresponding element is multiplied.

But multivariable Lanchester equation have ignored the effective striking distance of combat unit and combat unit spacing to the impact of operation result, and the combat unit model in multivariable Lanchester equation is single armament systems or the optimal in structure of loading single armament systems, can not be directly used in and describe naval vessels Campaign Process, need to carry out specific aim improvement to it, development is as follows:

(1) deduction model of fighting is improved

Multivariable Lanchester equation have ignored the effective striking distance of combat unit and combat unit spacing to the impact of operation result, and Campaign Process only changes with operational time, is to fight a kind of time against deducing model.Naval vessels Campaign Process is not only relevant, also relevant with the battle station of both sides at war with the duration of fighting, and is that model is deduced in a kind of space-time operation.Improving fights, and to deduce the core concept of model be consider that the effective striking distance of combat unit and combat unit spacing are on the impact of operation result, set up a kind of space-time and deduce model.Specifically improve one's methods as follows:

The effective striking distance of combat unit is determined jointly by Weapon Range and detection range.When both are equal, the effective striking distance of combat unit equals Weapon Range (detection range); Both not wait time, the effective striking distance of combat unit equals the minimum value in Weapon Range and detection range.Provide computing function (formula 2):

S(x)＝min(D _x(f)，D _x(t))......................................................(2)

Wherein S (x) represents the effective striking distance of combat unit x, D _xf () represents the Weapon Range of combat unit x, D _xt () represents the detection range of combat unit x, function min (x, y) equals x, the minimum value in y.

Known effective striking distance computing formula S (x), if the distance between red combat unit x and blue party combat unit y is D (x, y), then as D (x, y), during >S (x), red combat unit x cannot hit blue party combat unit y.In like manner, as D (x, y) >S (y), blue party combat unit y cannot hit red combat unit x.

Combat unit spacing and effective striking distance are on the impact of belligerent result for convenience of description, introduce striking capabilities function C (x, y), as shown in Equation 3:

$C(x,y)=\left\{\begin{array}{c}1,x\&GreaterEqual;y\\ 0,x<y\end{array},...\left(3\right)\right.$

On the basis of multivariable Lanchester equation, in conjunction with effective striking distance computing function S (x) and striking capabilities function C (x, y), for multivariable Lanchester equation increases a striking capabilities matrix, the factor affecting side's fighting efficiency is increased to four: the numbers matrix of combat unit, loss factor matrix, Fire Distribution matrix and striking capabilities matrix.Improve the Lanchester equation after deduction model of fighting, as shown in Equation 4:

Wherein n × m matrix, represent that red i-th class combat unit is to the striking capabilities of blue party jth class combat unit, when blue party jth class combat unit is within red i-th class combat unit effective striking distance, otherwise d (R _i, B _j) represent red i-th class combat unit and to the distance between blue party jth class combat unit; S (R _i) represent the effective striking distance of red i-th class combat unit.φ, φ _ji, D (R _i, B _j), S (B _j) represent the parameter corresponding with red of blue party, repeat no more.

(2) combat unit model is improved

Combat unit model in multivariable Lanchester equation is single armament systems or the optimal in structure of loading single armament systems, and naval vessels are a kind of optimal in structures of loading multiple armament systems.When calculating combat unit model is the loss factor of the naval vessels loading multiple armament systems, can not be added by the loss factor being loaded into all armament systems on platform simply, the weapon (Fire Distribution) needing certain target of consideration strike to use and this armament systems are to the loss factor of target.

Being of core concept improving combat unit model returns the optimal in structure of loading multiple armament systems to be single armament systems, and the concrete grammar taked is loss factor computing function ψ (R, B) providing multiple-weapon platforms:

ψ(R,B)＝-(A*λ*γ)..................................................(5)

ψ (R, B) represents that red combat unit R is to the loss factor of blue party combat unit B.Wherein A=(a ₁, a ₂..., a _m) be red combat unit load various weapons fight force value vector; λ=(λ ₁, λ ₂..., λ _m) be red combat unit load various weapons Fire Distribution vector, when weapon i distribute hit blue party platform B time λ _i=1, otherwise λ _i=0; γ=(γ ₁, γ ₂..., γ _m) the striking capabilities vector of various weapons that loads of red combat unit, the γ when effective striking distance of weapon i covers blue party platform B _i=1, otherwise γ _i=0.

(3) modified Lanchester equation

Entered the improvement of above two steps, the type that can be improved Lanchester equation is as follows:

Suppose: red has M class optimal in structure, blue party has N class optimal in structure, red i-th (i=1,2 ..., M) and class optimal in structure is mounted with R _iclass weapon, blue party jth (j=1,2 ..., N) and class optimal in structure is mounted with B _jclass weapon.Modified Lanchester equation is as follows:

$\left\{\begin{array}{c}\stackrel{\&CenterDot;}{L}=-(P*W)\&times;H\\ \stackrel{\&CenterDot;}{H}=-(Q*E)\&times;L\end{array}\right.,...\left(6\right)$

Wherein H=(h ₁..., h _m) ^t, L=(l ₁..., l _n) ^t, h _i, l _jthe fight force value vector of each armament systems of fight force value vector sum blue party optimal in structure of each armament systems of red optimal in structure respectively; represent that in vector, each element is respectively to time t differential, p=(p _ij) _{n × m}the loss factor matrix of red optimal in structure i to blue party optimal in structure j, W=(w _ij) _{n × m}red optimal in structure i to the Fire Distribution matrix of blue party optimal in structure j, when platform i hit platform j time, w _ij=1, otherwise w _ij=0; Q=(q _ji) _{m × n}the loss factor matrix of blue party optimal in structure j to red optimal in structure i, E=(e _ji) _{m × n}blue party optimal in structure j to the Fire Distribution matrix of red optimal in structure i, when platform j hit platform i time, e _ji=1, otherwise e _ji=0; " * " representing matrix corresponding element is multiplied.

Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
