Profitability prediction in thermal power enterprise based on the improved system dynamics model

Abstract

This paper tries to improve the system dynamics model and to establish the model of the thermal power enterprise profitability by using Newton interpolation method to optimize the nonlinear function, MATLAB to fitting equation and data analysis; and through the VENSIM to present a simulation. The model is dissertated and validated by some thermal power enterprise's financial data. This model can provide enterprises with management decision-making reference.
