The invention discloses a complex electronic equipment failure risk transfer relation analysis method based on a model system. The invention provides a failure risk transfer relationship analysis model and a failure risk transfer relationship automatic analysis algorithm of equipment, and realizes automatic establishment of failure risk transfer relationships between upper and lower layers of constituent units such as subsystems, modules and components of complex electronic equipment. Compared with an existing method for manually analyzing the failure risk transfer relation of the complex electronic equipment, the invention has the advantages that the problems of high complexity, poor efficiency, insufficient accuracy and the like caused by manual analysis in traditional failure risk transfer relation analysis work are solved, and the failure risk transfer relation analysis efficiency and the design quality are improved.
Description
technical field [0001] The invention relates to the technical field of transmission relationship of failure risk of complex electronic equipment, in particular to a method for analyzing the transmission relationship of failure risk of complex electronic equipment based on a model system. Background technique [0002] In the process of analyzing the failure risk transmission relationship of complex electronic equipment, the analysis is often carried out by relying on the experience and subjective knowledge of the design team. At present, there is no automatic failure risk transmission relationship analysis method that can be applied in actual engineering, and it can only rely on experienced research and development. Designers rely on experience and subjective judgment, which often leads to incomplete and incomprehensible failure mode analysis, and it is easy to miss the transmission relationship between failure mode and failure risk, and the analysis efficiency is low.
