Variables in chemical process are mutually affected and chemical process failures are often caused by the chain effect of a number of variables, so some minor changes in variables can often lead to an unknown fault. In this paper, the multivariable correlations are studied from the perspective of the whole process, and PCC (Pearson Correlation Coefficient) is used to calculate the correlation coefficient...
Grey diagnosis method is introduced in this paper. Grey relation analysis is applied in model identification of the fault diagnosis. Take example for the fault diagnosis for shipboard chemical defense equipment. The grey diagnosis methods for shipboard chemical defense equipment are studied by applying grey system theory and database. The theory of fault diagnosis by grey relation degree is put forward...
