Quantitative Model of Enterprise Financial Risk Management Based on Nonlinear Differential Equation

In order to accurately assess the financial risks of enterprises, a quantitative model of enterprise financial risk management based on nonlinear differential equations is designed. According to the hierarchical running track of enterprises, 30 evaluation indexes are selected, the index weights are determined, and the financial risk evaluation index system is constructed. Constructing allocation judgment matrix based on binary allocation scale value. Copula nonlinear differential equation is selected to comprehensively quantify the risk management of enterprise financial portfolio. Realize the quantitative model of enterprise financial risk management. The accuracy of the design model is verified by experiments. The results show that the upper quantile of the design model analysis is closer to the standard value, which is consistent with the actual situation and is effective
