Description

Technical Field

[0001] The present application belongs to the technical field of aircraft collaborative mission system service quality assessment, and specifically relates to a service quality assessment method for aircraft collaborative mission systems. Background Art

[0002] At present, solving the problem of multi-aircraft cross-domain collaborative tasks in the form of service has gradually gained widespread attention and research. The collaborative task system using service-oriented architecture has the characteristics of multi-heterogeneity, virtualization, connectivity, distribution, easy scalability and on-demand service. Through the external form of service, it realizes the logical function of providing resources on demand internally and completes the established tasks.

[0003] However, facing the complex and ever-changing distributed environment, in order to realize the mapping relationship of "task-service-resource" and complete the dynamic organization and optimal allocation of resources, it is urgent to carry out service quality evaluation to provide a reference basis for resource organization and real-time decision-making within the collaborative task formation.

[0004] Currently, the measurement methods for service quality of service-oriented architecture include:

[0005] The direct measurement method reflects the service quality by collecting various indicators in the system. This method is mostly used for post-analysis. However, the service quality evaluation of the collaborative task system must support real-time decision-making, so it requires high real-time performance and is not applicable to this.

[0006] The indirect analysis method uses mathematical analysis to estimate various service quality indicators and can meet real-time requirements. However, existing research results are mainly aimed at the field of cloud computing services.

[0061] A service quality evaluation method for aircraft collaborative mission systems, such as Figure 1 shown.

[0062] Collaborative tasks can be divided into three categories: detection, interference, and delivery. Among them, the corresponding detection services include air search services, air target tracking services, and air target positioning services; interference services include support interference services; and delivery services include material delivery services and delivery guidance services.

[0063] The resources needed for detection services include radar and photoelectric radar. The performance of radar and photoelectric radar includes detection distance and detection angle range.

[0064] Aerial search services often appear in the pre-mission stage. Therefore, the factors that need to be considered in the quality of air search services include detection distance, detection angle, area search time, service response time and communication transmission rate. The performance calculation model of air search services is shown in the following formula 1: 1 Score the performance of the air search service itself, D i is the detection distance, D j is the detection angle, T i is the area search time, T j is the service response time, S is the communication transmission rate, α, β, γ are the relevant weights, where α+β=1.

[0065]

[0066] The factors that need to be considered for air target tracking services include detection distance, detection angle, tracking distance accuracy, tracking angle accuracy, tracking speed accuracy, area search time, service response time, and communication transmission rate. The performance calculation model for building air target tracking services is shown in Equation 2 below: 2 Score the performance of the aerial target tracking service itself, D i is the detection distance, D j is the detection angle, F a is the tracking distance accuracy, F b is the tracking angle accuracy, F c To track the speed accuracy, T i is the area search time, T jis the service response time, S is the communication transmission rate, α, β, ω, γ are the relevant weights, where α+β+ω=1.

[0067]

[0068] The factors that need to be considered for aerial target positioning services include detection distance, detection angle, positioning distance accuracy, positioning angle accuracy, positioning speed accuracy, area search time, service response time and communication transmission rate.

[0069]

[0070] As the environment changes continuously, the duration of the task continues to increase. Opening different detection resources at different time points should have different values. In the quality evaluation of detection services, the parameter γ is introduced to limit the performance scores of different detection services at different times.

[0071] When the mission duration is short, the number of aircraft and the resources they carry are sufficient. At this time, the strategy choice tends to find targets under the premise of protecting themselves. Therefore, the γ value of light mine detection is higher at the beginning. As the mission duration continues to increase, the aircraft may be damaged, the possibility of coordinated detection decreases, or it may be assigned to perform services with higher priority. Therefore, the γ value of light mine detection gradually decays; when the carrying resources are continuously consumed, or the number of aircraft is lost, the focus of the strategy choice will tend to be on the efficiency and speed of service completion, so the γ value of radar detection will continue to increase.

[0072] The values ​​of the parameter γ for different detection services at different task durations can be referred to as follows:

[0073] The resource required for interference services is ECM. The performance indicators of this resource include interference distance, interference angle, interference angle accuracy, interference range accuracy, target interference time, service response time and interference frequency. The performance calculation model for supporting interference services is shown in Equation 4 below: 4 To support the interference service's own performance score, B i is the interference distance, B j is the interference angle, Q a is the interference angle accuracy, Q b is the interference range accuracy, T i is the target interference time, T j is the service response time, S is the interference frequency, α, β, ω are the relevant weights, where α+β+ω=1.

[0074]

[0075] The resources needed for delivery services are materials and radars.

[0076] The factors that need to be considered for material delivery services include delivery distance, delivery range, quantity of delivered materials, distance measurement accuracy, and angle measurement accuracy. The performance calculation model for building material delivery services is shown in Equation 5 below: 5 Score the performance of the material delivery service itself, H i is the delivery distance, H j is the delivery range, Q a is the ranging accuracy, Q b is the angle measurement accuracy, N is the remaining quantity of materials, α, β, γ, ω are the relevant weights, among which α+β+γ+ω=1.

[0078] The factors that need to be considered for the delivery guidance service include guidance distance, guidance angle, distance measurement accuracy, angle measurement accuracy, area search time, service response time and communication transmission rate. The performance calculation model of the delivery guidance service itself is shown in Equation 6 below: 6 Score the performance of the delivery guidance service itself, D i is the guidance distance, D j is the guidance angle, Q a is the ranging accuracy, Q b is the angle measurement accuracy, T i is the area search time, T jis the service response time, S is the communication transmission rate, α, β, ω are the relevant weights, where α+β+ω=1.
