Predictive application of GM(1,1)model in ultra high temperature field
In the actual measurement test process,ultra-high temperature equipment will be encountered,which cannot be direct-ly detected due to the limitations of the standard or the entire industry.In view of the above problems,this paper uses the gray system theory to establish the GM(1,1)model according to a small number of temperature measurement points and evaluates the error size of the tested equipment by comparing the theoretical value calculated by GM(1,1)with the display value of the instru-ment.Experiments show that the GM(1,1)model can be used to evaluate the magnitude of the error that cannot be directly de-tected,which provides an idea for the occurrence of equipment that is difficult to measure in future work.
