Technical Field

[0001] This invention belongs to the field of helicopter system engineering technology, and specifically relates to a helicopter performance evaluation framework oriented towards requirements analysis. Background Technology

[0002] Helicopter performance evaluation is a technique that involves constructing an indicator system based on capability requirements and then using the data obtained from that system to conduct the evaluation. Performance evaluation primarily employs a reductionist approach, which involves aggregating lower-level indicators to obtain the evaluation values ​​for higher-level indicators.

Aerospace Defense, 2020, 3(1): 80-86) Based on the DoDAF2.0 framework, nine effectiveness simulation views, including EV1 to EV9, were designed, and a view-based equipment effectiveness simulation process was constructed. Effectiveness assessment in the field of fighter jets ([2] Sun Peng, Yang Jianjun. Combat effectiveness assessment of fourth-generation fighter jets [J]. Flight Missiles, 2010, 6: 68-72) An effectiveness assessment index system was constructed, and models such as survivability, maneuverability, information capability, and attack capability were established. The assessment results were obtained through simulation.

[0004] As can be seen from the above, the current effectiveness assessment is mainly based on the design of an indicator system for weapon and equipment capabilities, and cannot evaluate effectiveness according to different combat scenarios of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a requirements-oriented helicopter performance evaluation framework. This invention enables the analysis of the capability requirements of combat systems, equipment systems, and helicopter equipment in the context of information-based and system-of-systems warfare, and allows for performance evaluation of these systems under different combat scenarios.

[0006] The technical solution of this invention is a helicopter performance evaluation framework oriented towards requirements analysis, comprising: a combat system layer, an equipment system layer, and a helicopter equipment layer; the combat system layer is used to analyze the capability requirements, composition, and interrelationships between the combat system, and to conduct combat system performance evaluation; the equipment system layer is used to analyze the capability requirements, composition, and interrelationships between the equipment system based on the capability requirements, composition, and interrelationships between the combat system obtained from the combat system layer analysis, and to conduct equipment system performance evaluation; the helicopter equipment layer is used to analyze the capability requirements, composition, and interrelationships between the equipment system obtained from the equipment system layer analysis, to analyze the capability requirements of the helicopter equipment, and to conduct helicopter equipment performance evaluation.

[0007] In the aforementioned requirements-oriented helicopter performance evaluation framework, the combat system layer, equipment system layer, and helicopter equipment layer are all composed of four dimensions: requirements analysis dimension, capability analysis dimension, integrated design dimension, and performance evaluation dimension.

[0008] In the aforementioned requirements-oriented helicopter effectiveness assessment framework, at the operational system level, the requirements analysis dimension includes an operational system mission analysis view and an operational system scenario description view; the capability analysis dimension includes an operational system capability requirements view and an operational system capability decomposition view; the integrated design dimension includes an operational system composition view, an operational system activity analysis view, and an operational system activity-capability mapping view; and the effectiveness assessment dimension includes an operational system capability-effectiveness mapping view, an operational system effectiveness indicator decomposition view, an operational system effectiveness data view, and an operational system effectiveness assessment result view.

[0009] In the aforementioned requirements-oriented helicopter effectiveness assessment framework, the operational system layer's workflow is as follows:

[0010] The operational system mission and task analysis view generates a list of operational system missions and tasks, providing input for the operational system scenario description view. The operational system capability requirements view generates initial operational system capability requirements based on the operational system scenario description view and decomposes them into an operational system capability decomposition view. This view also provides input for the operational system composition view. The system architecture generated by the operational system composition view serves as the basis for analysis in the operational system activity analysis view. Simultaneously, the operational system activity analysis view generates a list of operational activities, and the operational system activity-capability mapping view generates capability requirement mappings. These capability requirements serve as input for the operational system capability decomposition view and are mapped to effectiveness indicators through the operational system capability-effectiveness mapping view. Through layer-by-layer decomposition, the operational system effectiveness indicator decomposition view yields an effectiveness indicator system. This system is then calculated or simulated to obtain effectiveness evaluation data. Finally, the effectiveness evaluation data is aggregated into an operational system effectiveness data view, ultimately generating an operational system effectiveness evaluation result view.

[0011] In the aforementioned requirements-oriented helicopter performance evaluation framework, at the equipment system level, the requirements analysis dimension includes an equipment system mission analysis view and an equipment system scenario description view; the capability analysis dimension includes an equipment system capability requirements view and an equipment system capability decomposition view; the integrated design dimension includes a combat system and equipment system mapping view, an equipment system activity analysis view, and an equipment system activity-capability mapping view; and the performance evaluation dimension includes an equipment system capability-performance mapping view, an equipment system performance indicator decomposition view, an equipment system performance data view, and an equipment system performance evaluation result view.

[0012] In the aforementioned demand-oriented helicopter performance evaluation framework, the working process at the equipment system level is as follows:

[0013] The Equipment System Mission and Task Analysis View generates a list of equipment system missions and tasks based on the Operational System Mission and Task Analysis View. The Equipment System Scenario Description View generates scenario descriptions based on the Equipment System Mission and Task Analysis View and the Operational System Scenario Description View. The Equipment System Capability Requirements View generates initial equipment system capability requirements based on the Equipment System Scenario Description View and decomposes them into an Equipment System Capability Decomposition View. The Equipment System Capability Requirements View also provides input to the Operational System and Equipment System Mapping View. The system architecture generated by the Operational System and Equipment System Mapping View serves as the basis for analysis in the Equipment System Activity Analysis View. Simultaneously, the Equipment System Activity Analysis View generates a list of operational activities, and the Equipment System Activity-Capability Mapping View generates capability requirement mappings. The capability requirements generated by the capability requirement mapping serve as input to the Equipment System Capability Decomposition View and are mapped to effectiveness indicators through the Equipment System Activity-Capability Mapping View. Through layer-by-layer decomposition, the Equipment System Effectiveness Indicator Decomposition View yields an effectiveness indicator system. The effectiveness indicator system is then calculated or simulated to obtain effectiveness evaluation data. Finally, the effectiveness evaluation data is aggregated into an Equipment System Effectiveness Data View, and ultimately, an Operational System Effectiveness Evaluation Result View is generated.

[0014] In the aforementioned helicopter performance evaluation framework oriented towards requirements analysis, at the helicopter equipment layer, the requirements analysis dimension includes a helicopter equipment mission analysis view and a helicopter equipment scenario description view; the capability analysis dimension includes a helicopter equipment initial capability requirements view and a helicopter equipment capability requirements view; the integrated design dimension includes a helicopter equipment interface interaction view, a helicopter equipment activity analysis view, and a helicopter equipment activity-capability mapping view; and the performance evaluation dimension includes a helicopter equipment capability-performance mapping view, a helicopter equipment performance index decomposition view, a helicopter equipment performance data view, and a helicopter equipment performance evaluation result view.

[0015] In the aforementioned demand-oriented helicopter performance evaluation framework, the working process of the helicopter equipment layer is as follows:

[0016] The helicopter equipment mission analysis view generates a list of helicopter equipment missions and tasks based on the equipment system mission analysis view. The helicopter equipment scenario description view generates scenario descriptions based on the helicopter equipment mission analysis view and the equipment system scenario description view. The helicopter equipment initial capability requirement view generates initial helicopter equipment capability requirements based on the helicopter equipment scenario description view and the equipment system capability decomposition view, and decomposes them into a helicopter equipment capability requirement view. The initial capability requirement view also provides input to the helicopter equipment interface interaction view and the helicopter equipment activity analysis view. The helicopter equipment interface interaction view inherits the capability interaction relationships generated by the equipment system activity-capability mapping view and generates interface requirements, which serve as input to the helicopter equipment activity analysis view. The combat activity list generated by the helicopter equipment activity analysis view is provided to the helicopter equipment activity-capability mapping view to generate capability requirements. On the one hand, it serves as input to the helicopter equipment capability requirement view; on the other hand, it is mapped to effectiveness indicators through the helicopter equipment capability-effectiveness mapping view. The effectiveness indicator system is obtained from the helicopter equipment effectiveness indicator decomposition view. Then, the effectiveness indicator system is calculated or simulated to obtain effectiveness evaluation data. Finally, the effectiveness evaluation data is aggregated into a helicopter equipment effectiveness data view, and finally, a helicopter equipment effectiveness evaluation result view is generated.
