[0024] In order to make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the drawings in the embodiments of this application.

[0025] In order to solve the above problems, the present application provides a method for constructing an inverted tree structure management model of aviation equipment technical requirements, which stores technical requirements in the form of an inverted tree structure and establishes association relationships, which helps to improve the identifiability of key information of technical requirements and the intuitive visualization of traceability relationships.

[0026] like Figure 1 As shown, the method for constructing a structure tree for aviation equipment R&D demand data management provided by this application includes the following process:

[0027] Step 1: Determine the R&D needs of aviation equipment. The R&D needs of aviation equipment are divided into stakeholder needs and system technical needs. Among them, stakeholder needs are the project feasibility study report approved by Party A or the user, the general development requirements, the use requirements and airworthiness requirements proposed by user pilots and ground crew, and other legal and regulatory requirements; system technical requirements are the technical status baseline of aviation equipment products, which are gradually formed and frozen as the R&D level deepens during the development of aviation equipment products. This application is to structure the data of stakeholder needs and system technical requirements of aviation equipment.

[0028] Step 2: According to the aviation equipment product breakdown structure (PBS), the system technical requirements of aviation equipment are divided into three levels, namely the top-level system technical requirements, the middle-level process system technical requirements and the bottom-level equipment / component technical requirements. The system technical requirements at each level are further divided into three layers, namely the input layer technical requirements, the current layer technical requirements and the output layer technical requirements. The "level" and "layer" are used to distinguish the system level and requirement type of the system technical requirements.

[0029] In this application, the system technical requirements are decomposed and allocated step by step from top to bottom according to the product breakdown structure (PBS) of aviation equipment, and finally a data management structure of the system technical requirements of aviation equipment models is formed.

[0030] Among them, "level" represents the system level. According to the product decomposition structure, the system technical requirements of aviation equipment products can be divided into top-level system technical requirements, intermediate-level process system technical requirements, and bottom-level equipment / component technical requirements.

[0031] In this application, the technical requirements of the intermediate process system can be multi-level. For example, a certain aviation equipment can be divided into five levels according to the product decomposition structure - equipment level, aircraft level, system level, subsystem level and subsystem level / equipment level. Then the system technical requirements of the aviation equipment are divided into five levels - equipment level requirements, system level requirements, subsystem level requirements, subsystem level / equipment level requirements, among which the equipment level requirements are the top-level system technical requirements, the subsystem level / equipment level requirements are the bottom-level equipment / component technical requirements, and the rest are intermediate process system technical requirements.

[0032] The system technical requirements at each level are divided into different types according to their uses, represented by "layers": the first layer is the input layer technical requirements, the second layer is the current layer technical requirements, and the third layer is the output layer technical requirements for output to the lower level. Among them, the number of output layer technical requirements for output to the lower level is less than or equal to the number of lower-level system technical requirements. There are no technical requirements for output to the lower level in the lowest-level device / component technical requirements.

[0033] Step three, establish a link relationship between system technical requirements and stakeholder requirements to construct a demand data management structure tree model, so that the demand data can establish a link relationship with the data of its adjacent level according to its level, wherein the input layer technical requirements of each level of system technical requirements have an input-output link relationship with the data of the output layer technical requirements of the stakeholder requirements and / or the upper-level system technical requirements, and the current layer technical requirements of each level of system technical requirements have an input-output link relationship with the data of the input layer technical requirements. At the same time, the current layer technical requirements of each level of system technical requirements have a link relationship as the input of the output layer technical requirements output to the lower level.

[0034] like Figure 2 As shown, on this basis, the present application also provides an aviation equipment R&D demand data management system 100, including:

[0035] The demand confirmation module 110 is used to determine the aviation equipment R&D demand, which is divided into stakeholder demand and system technology demand;

[0036] The requirement decomposition module 120 is used to divide the system technical requirements into three levels according to the aviation equipment product decomposition structure, including the top-level system technical requirements, the middle-level process system technical requirements and the bottom-level equipment or component technical requirements. The system technical requirements of each level are divided into three layers, including input layer technical requirements, current layer technical requirements and output layer technical requirements;

[0037] The requirement link module 130 is used to establish a link relationship between the system technical requirements and the stakeholder requirements to construct a requirement data management structure tree model, so that the requirement data can establish a link relationship between the level to which it belongs and the data of the adjacent level, wherein the input layer technical requirements of each level of system technical requirements have an input-output link relationship with the data of the output layer technical requirements of the stakeholder requirements and / or the upper-level system technical requirements, and the current layer technical requirements of each level of system technical requirements have an input-output link relationship with the data of the input layer technical requirements. At the same time, the current layer technical requirements of each level of system technical requirements have a link relationship as the input of the output layer technical requirements output to the lower level.

[0038] In addition, the system includes:

[0039] A stakeholder requirements module 140 for storing stakeholder requirements;

[0040] The input layer technical requirement module 150, the current layer technical requirement module 160 and the output layer technical requirement module 170, the input layer technical requirement module is used to store the input layer technical requirements in the system technical requirements at all levels, the current layer technical requirement module is used to store the current layer technical requirements in the system technical requirements at all levels, and the output layer technical requirement module is used to store the output layer technical requirements in the system technical requirements at all levels.

[0041] like Figure 2 The structure tree model of demand data management of a certain type of aviation equipment product in one embodiment of the present application is shown. The product decomposition structure tree of the aviation equipment product is divided into three levels, namely, equipment level, system level, and equipment level. In the early stage of development, a certain demand (number: 101) from a stakeholder is received and stored in the stakeholder demand module. When carrying out the equipment-level system design, demand No. 001 is received and stored in the input layer technical demand module. When carrying out the system design, demand No. 001 is transformed to form two demands 101 and 102, and stored in the technical demand module of this layer. After the system comprehensive design, it is determined that demand No. 101 should be assigned to system-level system A and system-level system B, and demand No. 102 should be assigned to system-level system A. Therefore, demand No. 101 is transformed into demand No. 201 and assigned to system-level system A, and stored in the technical demand module output to the lower-level system A, and demand No. 101 is transformed into demand No. 202 and assigned to system B, and stored in the technical demand module output to the lower-level system B. Transform requirement No. 102 into requirement No. 203 and requirement No. 204, assign them to aircraft system B, and store them in the technical requirement module output to the subordinate system B.

[0042] When designing system A, demand No. 201 is received and stored in the technical demand module of the input layer. After the system design is carried out, demand No. 201 is transformed to form two demands 301 and 302, which are stored in the technical demand module of this layer. After comprehensive system design, it is determined that demand No. 301 should be assigned to device A1, and demand No. 302 should be assigned to devices A1 and A2. Therefore, demand No. 301 is transformed into demand No. 401, which is assigned to device A1 and stored in the technical demand module output to the lower-level device A1. Requirement No. 302 is transformed into demand No. 402 and demand No. 403, which are assigned to device A2 and stored in the technical demand module output to the lower-level device A2.

[0043] After the design of equipment A1 is carried out, demand No. 401 is received and stored in the technical demand module of the input layer. After the system design is carried out, demand No. 401 is transformed into three requirements 501, 502, and 503 and stored in the technical demand module of this layer. Requirements No. 501, 502, and 503 are directly used as the basis for purchasing equipment A1 or continuing research and development.

[0044] The aviation equipment R&D demand data management method provided in this application stores and manages demand information in the form of a structure tree and establishes associations between data. This can improve the identifiability of key information on technical requirements in the aviation equipment product development process, and make its traceability and associations intuitively visualized; it is helpful to allocate development activities and output storage locations of product technical requirements by comparing with the organizational chart; it is helpful to clarify the organizational affiliation of data, and at the same time, it can clarify the data transmission relationship between organizations.

[0045] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
