Evaluation criteria of the failure detectability ().

Quantitative score	Detectability description	Explain
5	Very high difficulty	Cannot be detected: it cannot be detected by any means.

3	Secondary difficulty	Normally detected: it is normally detected through complex disassembly, installation, and testing equipment in a long time.
2	Low difficulty	Easily detected: it is normally detected in a short time by simple disassembly.
1	Very low difficulty	Directly detected: it is normally detected directly and quickly.
