Zhe Yang · Microcomputer Information · 2012
Based on the theory of risk assessment,this paper firstly analyzed the risk from the asset influence and frequency of threat,set up risk level structure of overseas iron ore investment,and presented the membership matrices for judgment set.Then,the neural network and fuzzy reasoning theory were applied to evaluate the risk of overseas iron ore investment to obtain its risk grade. Finally,by calculating the market risk of overseas iron ore investment shown how the method works,and the error analysis was applied to detecting effectiveness and reliability of the model performance.
