Description

Technical Field

[0001] The present invention relates to the technical field of military equipment demand analysis, and in particular to a scenario-based space-based land support demand analysis method. Background Art

[0002] With the construction of future equipment systems, a deeper coupling relationship will be formed between various equipments. The improvement of system capabilities is the change of capabilities caused by the coordinated development of the capabilities of various equipments in the system, rather than the simple improvement of single equipment capabilities and indicators. Therefore, higher requirements are put forward for equipment demand analysis, and it is necessary to carry out demand analysis from the perspective of improving system capabilities, especially the combat capability demand analysis under the complex environment, complex equipment, complex relationships, and complex confrontation relationships of the land battlefield. The traditional single equipment demand analysis method can no longer meet the capability development needs under the system capability construction. It is necessary to propose a demand analysis method for precision strike applications in complex land battlefields to provide method support for subsequent equipment demonstration, verification, simulation and deduction.

[0003] Traditional demand analysis, especially for the development of specific equipment, mainly focuses on the performance and function of the equipment itself, that is, a certain equipment or capability is regarded as an independent individual, and demand analysis is carried out around its accuracy, timeliness and other indicators, and then guides the subsequent equipment development. For example, when proposing the development requirements of a certain equipment, including accuracy, timeliness, information elements and other indicators, the work of indicator decomposition and refinement is carried out around such indicator requirements, and finally the detailed indicator requirements that can guide the equipment development are given.

[0004] The demand analysis method of the existing technical solution has the following shortcomings:

[0005] (1) Only the needs of single equipment development were considered, without in-depth consideration of the needs of equipment in system combat applications. The positioning of the equipment in the system and the relationship between it and other elements in the system were not analyzed in depth, and the needs of the future development of new equipment were not analyzed from a strategic perspective;

[0006] (2) The design and analysis of equipment usage scenarios focus on the application of the equipment itself, and the support and correlation of other elements in the system required for the equipment to exert its capabilities are not fully considered, resulting in a large gap between the demonstration scenario and the actual equipment usage scenario, or the actual scenario application is affected and restricted by other factors, resulting in the inability to effectively exert the capabilities of the equipment during the demand demonstration;

[0007] (3) There is no deep correlation between the performance of equipment effectiveness and the generation of system capabilities, that is, the capability advantages of a single piece of equipment cannot effectively support the performance of the entire equipment system capabilities. Summary of the invention

[0008] In order to solve the technical problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a scenario-based space-based land support demand analysis method, coordinate various elements within the system, carry out demand analysis in multiple dimensions, establish a complete set of demand refinement, element comparison, quantitative and qualitative characterization methods, and more intuitively express the processes, indicators of each stage and element and the relationship between the elements.
