Abstract
To explore the influencing factors in financial investment, fuzzy logic theory was applied to the decision-making of financial risk investment. Using the methods of system analysis and empirical research, the influencing factors of investment projects were comprehensively analyzed. Based on the fuzzy matrix and fuzzy comprehensive evaluation model, the uncertain factors were analyzed. The analytic hierarchy process was introduced to determine the weight of each indicator. The results showed that in the decision-making of financial risk investment projects, fuzzy consistent matrix method and fuzzy multi-attribute comprehensive evaluation method made the decision more reasonable. In summary, the analytic hierarchy process and the fuzzy comprehensive evaluation method constitute a comprehensive evaluation model. It can effectively overcome the respective shortcomings of decision making by using the model of AHP or fuzzy evaluation alone. In the financial risk investment environment, a satisfactory portfolio of high-risk and high-yield dual goals is obtained.
