Method and system for constructing component fault tree based on physics of failure

A system for constructing component fault tree based on physics of failure, comprising:

• a fault information database establishing module, configured to establish, based on common characteristics of component physics of failure and according to six layers based on physics of failure and category of the component, a component fault information database containing information of six layers based on physics of failure;
• a fault tree constructing module, configured to construct, based on the fault information database and according to the six layers based on physics of failure and logical relationship of physics of failure, a component fault tree of n levels of events of six layers based on physics of failure;
• and
• a fault tree simplifying module, configured to simplify the fault tree by means of common cause failure mechanism sub-tree transferring and common cause fault module sub-tree importing
• wherein the fault information database establishing module is further configured to determine, based on the common physical characteristics of component physics of failure, six information layers based on physics of failure, namely:
• information layer of fault mode, information layer of failure mode, information layer of failure site, information layer of failure mechanism, information layer of mechanism factor, and information layer of influencing factor;
• and
• to classify and organize failure cases and failure information to establish, according to six layers based on physics of failure, fault information database of the six layers based on physics of failure.
