[0044] Example 1:

[0045] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0046] The basic idea of ​​the present invention is to use a five-layer architecture for design and implementation, such as Figure 1 As shown, it includes the display layer, business application layer, basic support platform layer and data resource layer.

[0047] Display layer: Responsible for interacting with user operations. Based on the mission characteristics of equipment demand research and demonstration, it provides two usage modes: research and demonstration of new equipment models and positive improvement and enhancement of existing equipment models, and conducts deployment and demonstration.

[0048] Business application layer: responsible for implementing the main functions of business operations such as equipment basic information management, equipment demand management, demand baseline management, demand change management, and equipment comprehensive situation management. It adopts a unified design and hierarchical deployment plan and is configured according to the respective permissions of departments and users. It includes the equipment basic information management module, equipment demand management module, demand baseline management module, demand change management module, and equipment comprehensive situation management module;

[0049] Basic support platform layer: provides functional components such as structured analysis, formal analysis, link nesting, two-way tracking, mind mapping, tree structure, capability matrix, and permission setting, supports an integrated environment for information access, transmission, and collaboration, and realizes efficient development, integration, deployment, and management of personalized business applications.

[0050] Data resource layer: realizes the management of various types of data in the entire system, including equipment information data, equipment requirement data, requirement baseline data, requirement change data, etc., and technically supports data formats such as structured data and binary files.

[0051] Based on the above system architecture, the present invention constructs an equipment demand analysis and management system based on demand baseline, including: equipment basic information management module, equipment demand management module, demand baseline management module, demand change management module and equipment comprehensive situation module. The system function modules are composed as follows: Figure 2 shown.

[0052] 1. The basic information management module of equipment, based on model and type, carries out multi-level classification maintenance and management of basic information of equipment, providing basic data support for equipment demand analysis and management; establishes a model tree as the basis to realize the recording and tracing of the development process of different requirements in each stage of equipment demonstration and development, and grasps the deviation between requirements and baseline at any time, so as to truly achieve closed-loop control of demand traction and process control, such as Figure 3 shown.

[0053] The equipment basic information management module also includes a basic information quick import function. The first step in importing data is to process the basic information of the equipment according to the template; the second step is to select the document containing the basic information of the equipment; the third step is to import the data, select the document to perform the data import operation, and the system reads and identifies the data, judges the validity, and imports the data information into the database after verification. The data import process focuses on cleaning similar duplicate data and inaccurate data, effectively improving the quality of imported data;

[0054] The equipment basic information management module also includes information fuzzy query and precise query, and supports query according to equipment name, model, type, etc.

[0055] 2. The equipment demand management module categorizes and aggregates the equipment demand information reported by each participating research unit in the form of a decomposition structure tree at the system level, subsystem level, sub-subsystem level, and equipment level, realizing the information-based management and control of equipment demand;

[0056] The equipment requirement management module combines structured analysis and formal analysis methods, and adopts a process-oriented model to decompose and describe the process, that is, it structurally decomposes the equipment requirements according to the demand generation process of mission tasks, capability requirements, system requirements, model requirements, and verification and evaluation, and decomposes the input, output, resources and other content information of each link.

[0057] The entire equipment requirement is designed and implemented using a layer-by-layer design method during the research and development process, such as Figure 4 Equipment requirement decomposition hierarchical management is shown as follows:

[0058] T0 Equipment System Level: Design equipment system-level mission, performance, capacity, quality and other characteristics as high-level requirements specified for equipment;

[0059] T1 Subsystem level: Collect subsystem-level functional requirements, including functional interfaces with other subsystems, as subsystem-level requirements for the entire or main functional application; in the process of requirement decomposition, inter-system design requirements and derived requirements will be generated

[0060] T2 subsystem level: Based on the T1 requirements assigned to the subsystem and the collected subsystem functional requirements, define and organize subsystem level requirements;

[0061] T3 Equipment Level: Defines and collects equipment-level requirements provided by various units.

[0062] The relationships between equipment requirements at different levels are categorized into dependency and composition relationships. A dependency relationship is between two equipment requirements, where the satisfaction of equipment requirement Ti depends on the satisfaction of equipment requirement Tj, denoted as r1. A composition relationship is when a certain equipment requirement is composed of several other equipment requirements, denoted as r2.

[0063] 3. The demand baseline management module, based on the project requirements, gradually refines the capability catalog of each state and the overall development requirements at different development stages. The capability baseline starts from the equipment mission and comprehensively considers the external environment, and is comprehensively sorted out and determined according to typical mission profiles and information flows.

[0064] When establishing the equipment requirement baseline, the equipment requirement data of relevant units such as the demand submitters, research and demonstration parties, evaluation and confirmation parties, and development and testing parties are fully collected and managed. For the same requirement proposed by different units, the system uses different methods such as interval type, average type, and Boolean type to confirm and select. After the equipment requirement baseline is established, it is tracked and change controlled strictly according to the baseline status.

[0065] Let Q be the equipment demand proposed by the demand unit, Q i The i-th demand proposed by the equipment demand unit, Q i =(q1,q2,……,q n ), where i = 1, 2, ..., n, where n is the number of demand points. In the system, the same equipment demand can have one or more items. To fully consider the needs of various units, the system supports equipment demand confirmation and selection using various methods, such as interval, average, and Boolean types.

[0066] Interval selection is to identify the minimum and maximum values ​​of all equipment requirements, and finally make the value of the equipment requirement index fall within a certain interval, that is, Q i The indicator range is [minq i , maxq i ], where (i=1, 2,…, n).

[0067] Average value selection: calculate the average value of the data submitted by different units for the same requirement, and compromise to set the final equipment requirement index information. i The indicator is Q i =Average(q1,q2,…,q n ), where (i=1, 2,…, n).

[0068] Boolean selection is used for equipment requirement indicators that have no dimension or cannot be measured. For example, under combat conditions, equipment is required to have real-time information communication and data transmission capabilities. This type of equipment requirement indicator information is parsed and merged using text parsing methods.

[0069] 4. Requirement change management, to achieve tracking and maintenance of new or modified requirements, to ensure that requirements have "two-way" traceability, and to clearly and effectively define the requirements content and the relationship between requirements through the model, including requirement attributes, requirement identification, and requirement traceability relationships.

[0070] The requirement change management module can record the change process information of each requirement, including the content before and after the requirement change, difference mark information, changer, change time, review status, review results, reviewer, review time and other information.

[0071] The demand change management module also includes demand linking and demand tracking functions, which support the creation of link relationships between different demand items and can track the equipment demand items associated with the demand through link association. The system can associate and filter the links and finally form a view. The two-way tracking of demand is as follows: Figure 5 shown.

[0072] The requirement change management module also includes a requirement version comparison and analysis function, that is, comparing the differences between any two versions of the requirement, and being able to intuitively display the differences using different colors after comparing them.

[0073] The demand change management module also includes a data authority function, that is, different users in different units can only perform change management on system data within their authority range.

[0078] S64. Equipment requirement change tracking: Changed requirements follow the same execution process as the original requirements. The system promptly updates the requirement change status and notifies relevant R&D and testing units, thereby making the impact of the change transparent.

[0079] 5. The equipment comprehensive situation module analyzes and displays equipment demand information in various forms such as mind maps, tree analysis diagrams, and decision matrices.

[0080] 1) Mind Map: Systematically organize equipment requirements and construct and display structured knowledge in the form of knowledge visualization, promote the correlation analysis of the internal logical relationship of demand data, and form analysis demand aggregation indicators through flexible combination, effectively supporting the leaders' analysis and decision-making on equipment demand demonstration research.

[0084] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
