Abstract

Abstract

The prediction model is the premise and foundation of effectively dealing with sudden water pollution accidents.To improve the accuracy of the prediction model,a new parameters identification method was proposed in this paper.This paper first built a prediction model from the perspective of the inverse problem and Bayesian,and then designed a new identification method based on the chaos theory,particle swarm optimization,differential evolution and Metropolis-Hastings sampling method,i.e.IPSO-DE-MH.Finally,the effectiveness and accuracy of the designed method were verified by numerical analysis.The results showed that the new method could better identify the model parameters,and provide a new idea for the construction of an emergency prediction model.
- parameter identification,
- particle swarm optimization,
