Analysis of supply chain finance risk assessment based on numerical analysis algorithm

To promote the coordination and stability of supply chain finance improve financing environment small medium-sized enterprises, this paper designs a risk assessment analysis platform. Combining characteristics large amount data, numerical algorithm is introduced in process platform design, extrapolation method used to calculate assessment- related data. make calculation faster data more accurate, central difference quotient accelerate downtime mechanism introduced. Firstly, approximation formula for constructed, followed by construction sequence variable steps obtain approximations. Finally, obtained approximate values are construct an interpolating polynomial, constant term which final factor, through continuous iteration. verify effectiveness analysis-based financial assessment, simulation results show that accuracy as high 99% time required 17 seconds higher than other models, verifies can rapidity assessment.
