Research of reliability data analysis and optimization for interior system

In order to solve the hidden weaknesses in the design and manufacturing process, a method of reliability design optimization is established. Through the analysis of fault data, considering design and manufacturing process, it is likely to dig out the hidden causes of the fault. Then based on the results of the investigation, some effective methods can be carried out to fundamentally solve the problems, thereby improving the reliability and market competitiveness of the aircraft throughout its life cycle. In this paper, the research on reliability design optimization of interior system based on fault data is implemented.
