Abstract

The invention discloses a quality quantitative evaluation method for a large-scale complex aerospace system. The quality quantitative evaluation method comprises the steps of: firstly, extracting a plurality of elements from the aerospace system research and development process; secondly, establishing an incidence matrix C according to correlation between the elements; thirdly, establishing at least three levels of evaluation criteria separately for evaluation key points of the plurality of elements, and acquiring a quality level value matrix P of each element according to the evaluation criteria; and finally, calculating a quality comprehensive level value L of the aerospace system by adopting a formula shown in description. The quality quantitative evaluation method conducts preliminary evaluation on development quality of the plurality of elements of the aerospace system, calculates the more scientific and reasonable final quality comprehensive level value of the large-scale complex aerospace system according to the incidence matrix relation between the elements and utilizing a weighted average method of linear algebra, makes the final quality comprehensive level value closer to the real situation of overall quality of the aerospace system, and is conducive to research and improvement of the aerospace system.

Description

technical field [0001] The invention relates to the technical field of quality evaluation of large and complex aerospace systems, in particular to a quality quantitative evaluation method for large and complex aerospace systems. Background technique [0002] Large and complex aerospace systems refer to large-scale equipment such as launch vehicles, artificial satellites, space vehicles, and detectors that can complete complex tasks in a space environment. Large and complex aerospace systems have their own characteristics. First, system quality problems and defects cannot be fully detected through ground pre-tests, mainly because the space environment and mission status are difficult to fully simulate on the ground, and the production quantities of such systems are usually small and cannot be applied. Routine quality inspection methods such as sampling inspection; second, it is difficult to maintain and maintain such systems during the execution of tasks, mainly because most ...
