Applicability of risk identification methods.

Serial number	Recognition methods	Applicability
1	Expert survey method	It is suitable for initial risk identification from qualitative aspects.
2	Statistical method of historical records	It is applicable to predict the risks of new projects from qualitative aspects.
3	Field investigation method	It is suitable for identifying and forecasting some dynamic risk factors.
4	Fault tree analysis	It is applicable to risk identification with less direct experience.
5	Flowchart method	It is suitable for project risk identification in stages.
6	Cluster analysis	It is applicable to risk identification with similar or similar attributes.
7	Fuzzy recognition method	It is applicable to situations where risks are uncertain.
8	Artificial neural network	It is suitable for small sample risk classification and recognition.
