Study on Multivariate Nonlinear Combination Prediction of Gas Emission

Considering source limitations and modeling form sensitivity of the existing monadic linear forecasting method,multivariate nonlinear combination prediction model of gas emission is built by induced ordered weighted geometric averaging(IOWGA) operator.The engineering examples show that this prediction model has various advantages such as high prediction accuracy,good data credibility and ideal prediction effect,etc.It can be applied to the coal mine safety production forecast.
