[0020] 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.

[0021] This application is based on the business process of the detailed design stage of aircraft products. Starting from different dimensions such as the professions involved in aircraft development, project management plan control, and time management, it analyzes the business data involved and the relationship between the data, and constructs a dimensional model for digital model progress monitoring in the detailed design stage of aircraft development. It describes the relationship between project control and R&D organization data, realizes the connection and integration of product digital models in different dimensions, and improves control efficiency.

[0022] like Figure 1 As shown, the method for constructing a dimensional model for monitoring the progress of aircraft product R&D digital simulation provided in this application includes the following process:

[0023] Step S10, convert the key indicators involved in the business process of digital model progress monitoring in the detailed design stage of product development into key indicators that can measure the execution progress. The key indicators that can measure the execution progress include the expected release quantity, the actual release quantity, the change compared with the previous day, the quantity in each state and the proportion of the quantity in each state.

[0024] The business process of digital model progress monitoring in the detailed design stage of product development is composed of a series of activities. The direct result of these activities is data. The data items generated by the business process at different stages are also changing. Therefore, in this application, the key indicators involved in the process are sorted out and precipitated into key indicators that can measure the execution progress, forming the results shown in Table 1.

[0025] Table 1 Key indicators

[0026]

[0027] Step S20: Determine the dimensions of the dimensional model according to the progress monitoring requirements of management and control personnel at different levels. The dimensions include at least the time dimension, the digital model status dimension, the professional dimension to which the digital model belongs, and the personnel dimension.

[0028] Dimensions generally refer to the process of business occurrence or analysis angle, describing the context of who, when, and what scope. This application starts from the needs of control personnel at different levels to monitor the progress of the work. It is necessary to meet the control personnel's control of the overall progress. Each technical leader must not only meet the project control requirements but also master the situation within the profession. Individuals must know their work efficiency and the comparison with the average efficiency. Therefore, the model should have time dimension, digital model status dimension, digital model professional dimension, personnel dimension, etc., and determine the granularity of each dimension.

[0031] Step S30: construct a data set according to the key indicators and the dimensions of the dimensional model.

[0032] By performing data analysis and fact confirmation on the key indicators of step one and the analysis dimensions of step two, the determined data sets include: time dimension data set (i.e. timetable 3), professional dimension data set (i.e. professional table 4), project dimension data set (i.e. project breakdown structure table 5), personnel dimension data set (i.e. personnel table 6), digital model dimension data set (i.e. digital model information table 7) and fact dimension data set (i.e. fact table 8).
