Abstract

The optimisation device ( 1 ) comprises means ( 4 ) for inputting data, means ( 2 ) for defining, on the basis of input data, time windows of availability and efficiency, relative to resources in consideration, an element ( 6 ) for expressing a space of solutions, i.e. said time windows, as probabilities, generating time-continuous functions in compliance with said time windows, an element ( 8 ) for optimising the resource allocation plan from the solutions space expressed as probabilities in this way, and user means ( 11 ) for using an optimal allocation plan defined in this way.

First claim

The invention claimed is:

1. A system for missile weapons assignment for handling airborne threats in the military field, said system comprising:
a first unit for retrieving information relating to a considered situation;
a second unit for processing said information to deduce an engagement proposition therefrom, by firstly determining firing windows on the basis of said information and then deducing the engagement proposition on the basis of said firing windows, said engagement proposition specifying the missile weapons assignment and firing instants for handling the airborne threats; and
a third unit for implementing a step of approving the engagement proposition, an engagement being carried out in accordance with the engagement proposition approved by said third unit,
wherein said second unit comprises an automatic device for optimising a weapon resource allocation plan, said device comprising:
means for inputting data;
first means for determining, on the basis of the input data, weapon firing windows of availability and effectiveness relating to missile weapon resources;
second means for determining, using said weapon firing windows, an optimal resource allocation plan for said missile weapon resources; and
user means using an optimal allocation plan determined by said second means,
wherein said second means comprises:
a first element configured to probabilise a solution space, namely, said weapon firing windows, by generating continuous functions as a function of time that comply with said weapon firing windows, wherein said first element is configured to implement an interpolation on the basis of performance points so as to obtain a continuous probability model of said solution space, and wherein said interpolation is a Bezier spline interpolation; and
a second element configured to optimise the allocation plan on the basis of said solution space thus probabilised.

2. The system according to claim 1 , wherein said means for inputting data comprises means for allowing data to be automatically supplied.

3. The system according to claim 1 , wherein said means for inputting data comprises means for allowing an operator to input data.

4. The system according to claim 1 , wherein the user means comprises display means configured to display the optimal allocation plan on a screen.

5. The system according to claim 1 , wherein said means for inputting data and said user means are part of a human-machine interface.

6. The system according to claim 1 , wherein said second element is configured to carry out a particle swarm optimisation.

7. The system according to claim 1 wherein said first unit comprises at least one radar unit that transmits information to said device relating to an air picture of the environment of an area to be protected by said system.

8. The system according to claim 1 further comprising a human-machine interface allowing an operator to complete an approval.

9. The system according to claim 1 , further comprising display means configured to display the engagement proposition approved by said third unit.

10. A method for handling airborne threats in the military field, comprising missile weapons assignment for handling the airborne threats, which method implements the following successive steps:
α) retrieving information relating to a considered situation;
β) processing said information to deduce an engagement proposition therefrom, by firstly determining firing windows on the basis of said information and then deducing the engagement proposition on the basis of said firing windows, said engagement proposition specifying the weapons assignment and firing instants for handling the airborne threats; and
γ) approving the engagement proposition, an engagement being carried out according to the engagement proposition,
wherein, during step β), the engagement proposition is determined by optimising a weapon resource allocation plan, wherein the following steps are automatically implemented:
A) generating data and determining, on the basis of the generated data, weapon firing windows of availability and effectiveness relating to missile weapon resources; and
B) determining, using said weapon firing windows, an optimal resource allocation plan for said missile weapon resources that is subsequently used,
wherein, during step B), the following successive operations are implemented:
a) determining the probability of a solution space by generating continuous functions as a function of time that comply with said weapon firing windows by implementing an interpolation on the basis of performance points so as to obtain a continuous probability model of said solution space, and wherein said interpolation is a Bezier spline interpolation; and
b) optimising the allocation plan on the basis of the solution space thus probabilised.
